- What should be paid attention to during the use of hard tooth surface gear reducer?The hard tooth surface gear reducer must be located under the flat propulsion base, and the anchor bolts must be driven and frozen.TRANSMISSION - HARDENED SURFACE REDUCER - Each connecting shaft of the working machine, machine equipment must be precisely directed to the main working limit of the center line shaft end and the output end of the reducer manufactured according to h6.The internal threads of transmission components, such as couplings, pulleys and sprocket chains, must be manufactured in accordance with the corresponding public service restrictions to avoid installation.Too tight will destroy the rolling bearings, too loose a fit will jeopardize all normal drive transmission.When the transmission parts such as sprocket chain and transmission gear are installed on the shaft, the rolling bearings should be as close as possible to reduce the bending stress of the shaft.When installing the motor on the hardened gear reducer, unsalted butter should be modified on the hole wall and keyway at the top of the worm to avoid over-tight installation and long-term rusting of the hole shaft.When ordering various hard tooth surface reducers, if the electric
- Structural characteristics of cylindrical gear reducerCylindrical gear reducer is one of many reducers.For it, we must first analyze its structure.We may not yet know that its structural features can be divided into several levels.Let's take a look at it in detail.(1) According to the structural characteristics, it is divided into 1-stage reducer, 2-stage reducer, 3-stage reducer and multi-stage gear reducer.(2) The cylindrical gear reducer is mainly composed of parallel shaft gears, cylindrical gears, sealing rings, transmission shafts and boxes.(3) The first-stage transmission ratio is generally 8-10, mainly to avoid excessive contour.If I is required to be greater than 10 (I represents the transmission ratio), a two-stage cylindrical gear reducer is used.(4) The 2-stage gear reducer is suitable for the case where the transmission ratio is 8-50, and the total intermediate distance between the high and low speed stages is 250-400mm (5) The 3-stage is used for the use requirements that require larger transmission.cylinder
- What is the standard for installing a hardened gear reducer?Hard tooth surface reducers are widely used in industrial and large-scale transmission-related equipment, and parts that have not been inspected, accepted by the technical and inspection department, unprinted and wet-painted are prohibited from being equipped.The assembly, partial assembly and final assembly of the hardened gear reducer must be carried out in accordance with the equipped process sequence without process intervention.The parts of the hard tooth surface reducer should be cleaned before being equipped. The rolling bearings should be cleaned with gasoline or high-quality cleaning agent, and then dried with compressed air.When equipped, each mating surface shall not be corrected when equipped.Matching parts are required, except for repairing keys and keyways.Before the rolling bearing is installed on the shaft, the paint should be preheated and the thermal expansion should be calculated.The hard tooth surface reducer should be debugged after being equipped, and the debugging speed should be close to the rated working speed of the reducer.It is strictly forbidden to add abrasives and impurities to the lubricating oil during debugging, and the contact ratio of the tooth surface should meet the requirements.After passing the hard tooth surface reducer, the skill assessment part will be printed and identified.
- Whether the oil return of the cycloidal reducer is smooth? An important factor for the oil leakage of the cycloidal reducerOil leakage of cycloid reducer is one of the common faults of cycloid reducer, and it is a headache. How to effectively control oil leakage is of concern to people.Whether the oil return of the cycloid reducer is smooth is also an important factor for the oil leakage of the cycloid reducer.The smooth flow of oil return is to make the oil that may leak outside flow back into the tank relatively smoothly.For example, the oil splashed on the inner wall of the box needs to be made to flow back to the oil pool in the box as soon as possible, so the inner wall of the cycloid reducer box cover is made into an arc shape, in order to prevent the oil from staying at the shaft head sealing device , in order to prevent the oil from gradually leaking out of the box along the shaft head, the oil groove type sealing device is adopted at the shaft head, and there is an oil return essence at the lower end of the oil groove, so that the oil accumulated in the oil groove can flow back into the box to prevent leakage.The oil return tank with a rectangular section on the seat surface of the cycloidal pinwheel reducer box can make the oil splashed on the inner wall of the box cover drip along the inner wall, collect into the oil return tank, and then flow back to the oil pool.The size of the reflux tank is large
- What are the operating procedures for the servo planetary reducer?Everyone is quite familiar with the servo planetary reducer. Many users do not know the operation process when using the reducer, which leads to failure. Today, the servo planetary reducer manufacturer will give you a brief introduction based on years of experience: the servo planetary reducer is installed. In principle, the model of the reducer bracket is determined according to the size of the output shaft diameter of the servo planetary reducer. As long as the interface form and size match, the size of the output shaft of the servo planetary reducer can be adjusted up and down within a certain range for the model of the servo planetary reducer bracket. branch.If the servo planetary reducer bracket with connection plate is selected, if the installation size of the servo planetary reducer does not match the reducer bracket, within a certain range, our company can adjust the connection between the speed connection plate and the servo planetary reducer to meet user requirements.Bapman introduced the operating procedures of the servo planetary reducer: 1. Inspection before starting ①, the reliability of the fastening of each fastener; ②, whether the oil level of the lubricating oil meets the requirements; ③, whether the wiring of the oil supply pump is correct;
- How to solve the vibration of the planetary reducer(1) Choice of vibration measurement method: There are two measurement methods for the vibration of the planetary reducer gear unit, one is to measure the vibration of the box and the other is to measure the vibration of the shaft.It is also often more effective to combine these two measurement methods to obtain the absolute movement of the shaft in the gear unit.For planetary reducer gear units supported by rolling bearings, the radial clearance of the bearings is small, and the relative movement between the bearings and the box is also small, so the vibration measurement of the box should be used.For gear units supported by ordinary sliding bearings, shaft vibration measurement or box vibration measurement can be used.However, when the frequency is in the range of 0-500Hz, it is not easy to measure small vibrations due to the insensitivity of the box vibration measurement, and the shaft vibration measurement should be used.The vibration measurement of the box can obtain a wide frequency range and its dynamic characteristics, which can provide the necessary basis for the analysis of the meshing frequency of the gear teeth.(2) Shaft vibration measurement: http://www
- How do planetary reducer manufacturers solve the problem of water immersionThe application range of planetary reducer is more and more extensive, and it is used in various automatic mechanical equipment, so its working environment is also different.For example: the planetary reducer used by the manipulator, some of its working environments are high-frequency repeated operations, some of which are intensive impact operations; bumpy and vibration operating environments, etc.Planetary reducers are used in different environments, and various glitches may occur due to certain reasons or accidents.Among them is the flooding failure of the planetary reducer, and the operation has stopped. What should I do?The following planetary reducer manufacturers will provide you with quick solutions to make the planetary reducer work again.1. First of all, the planetary reducer manufacturer should observe the external conditions, first do cleaning work, and wipe off the sludge and impurities on the surface of the servo planetary reducer.What needs to be paid attention to during the process is to handle it with care, do not damage the surface of the planetary reducer, let alone rotate the motor shaft.Because at the moment we don't know what the internal failure is.2. Next
- How to choose the gear of the planetary reducerThere are many factors to be considered in the use of planetary reducers. The most important thing is how to choose the appropriate gear. Choosing the appropriate gear can not only reduce the noise of the reducer, but also make the equipment work more efficiently. Otherwise, if the gears do not match and do not Reasonably, the reducer won't work.So, how to choose the gear of the planetary gear reducer?When selecting gears, in addition to paying attention to the fact that the hardness of the working tooth surface of the pinion is slightly higher than that of the working tooth surface of the large gear, the following should also be noted.1. On the premise of satisfying the bending fatigue strength, when the center distance of the reducer is fixed, more gears should be selected to improve the coincidence degree of the gears, make the transmission stable and reduce noise.Under the premise of meeting the transmission requirements, the teeth of the large and small gears should be interlocked as much as possible to disperse and eliminate the influence of gear machining errors on the transmission, and avoid periodic meshing of the teeth of the large and small gears, so that the transmission is stable.
- What are the measures to reduce the return error of the planetary reducer?The relationship between planetary gear backlash and return error: The planetary gear reducer is composed of multiple planetary gears, the inner ring gear of the sun gear and the transmission shaft, and the return error of each planetary gear is converted into a sun gear, and then calculated uniformly.The calculation of the return error of the planetary reducer can be summarized as two comprehensive calculations: 1. The comprehensive formula of the return error of the planetary gear: when the sun gear is used as the output, the ring gear is fixed, and the planetary gear is used as the output, the return error is generally converted into the return of the sun gear Error, after calculating the return stroke error of the sun gear, consider the temperature rise and torque deformation of the shaft.2. The comprehensive formula of the return error of the planetary gear transmission chain: the return error problem is actually the sum of the return errors of the planetary gears at all levels. In the calculation process, the actual situation of the planetary gears at all levels should be considered. According to its inherent characteristic parameters , the calculation resource allocation provides the corresponding correction model coefficients, and the planetary gears at all levels are adjusted through continuous correction coefficients
- How to maintain the long-lasting service life of the planetary reducerHow to maintain a long service life of the planetary reducer?This is a problem for every planetary reducer user.It is not difficult to realize its value and long-term service life by strictly following the use requirements of the reducer and carefully maintaining it.The debugging time of the reducer should not be less than two hours.The standard of normal operation is smooth operation, no vibration, no noise, no leakage, no impact.If there is any abnormality, it should be cleaned up in time.After the reducer is aligned according to the market demand, a more ideal transmission system effect and a longer service life can be obtained.When the reducer is installed, special attention must be paid to the alignment of the transmission center axis, and the alignment error must not exceed the use compensation of the coupling used by the reducer.There are many types of couplings that can be selected for the reducer, but do not use steel fixed couplings. The installation of this type of coupling is difficult. Once the installation is not suitable, the load will increase and the bearing will be easily damaged.The output shaft may even break.
