- What are the advantages of the pin output structure of BWY12-59-2.2KW cycloidal pinwheel reducer?The pin-type output structure of the BWY12-59-2.2KW cycloidal pinwheel reducer is the core force transmission component of the cycloidal transmission. It is suitable for 2.2kW power, 59 speed ratio, 12 The structural design of the No. 1 machine base fits the motion characteristics of the cycloidal pinwheel transmission under medium-load, medium- and low-speed conditions. Compared with the gear-type direct-connected output, it has significant advantages in torque transmission, operating stability, and working condition adaptability. The specific advantages are as follows: 1. Multi-pin load sharing, strong impact resistance: the output pins are evenly distributed around the circumference (the conventional configuration of the No. 12 machine base is 10-12 root) and the pin hole to transmit force, dispersing the torque of the cycloidal wheel to multiple pins to bear simultaneously, avoiding stress concentration at a single point, effectively buffering the impact load caused by equipment starting, braking and load fluctuations, adapting to working conditions with instantaneous impact such as transportation, mixing, and lifting, and meeting the actual use needs of 2.2KW medium-load equipment. 2. High transmission efficiency and torque transmission

Routine inspection (performed every shift/daily, the core inspection is the working condition of the pin shaft output end). Check the output end sealing part (oil seal, flange joint surface), there is no gear oil leakage, the connection between the pin-type output shaft and the load coupling is not loose, and the flat key/ The locking bolts do not slip or fall off; monitor the operating sound of the reducer, and the pin-type output structure transmits force without 'clicking' impact sounds or 'squeaking' Abnormal noise, the vibration amplitude of the whole machine is ≤0.15mm, and there is no abnormal jitter; touch the reducer housing and output shaft end, the temperature rise is ≤40℃ (when the ambient temperature is ≤40℃, the housing temperature is ≤80℃), there is no local overheating at the matching part of the pin and the pin hole; check the oil level window, the lubricating oil level is maintained at 1/2-2/3 of the oil level window, there is no emulsification, discoloration, and no metal debris floating; Confirm that the output end protective cover is intact and the pin-type transmission
- How to solve the problem of poor adaptability of the K97-27.9-15KW reducer splash lubrication system to the installation posture and working conditionsThe K97-27.9-15KW reducer is a hard-tooth surface model with medium to high power of 15kW and a transmission ratio of 27.9. The sensitivity of the splash lubrication system to the installation posture and working conditions is rooted in the passive structure that lubrication relies on gear oil. Based on the parameter characteristics of this model, the adaptability of the system can be improved through three types of measures: installation optimization, lubrication system modification, and working condition adaptation adjustment. The specific plans are as follows: 1. Adaptation optimization plan for installation attitude deviation. The splash lubrication of this model of reducer is adapted to horizontal installation by default. If non-standard installation such as tilted or vertical is required, the oil level and oil guide structure must be adjusted to ensure the gear oil and bearing lubrication effect. 1. Accurately check the oil level for non-horizontal installations (1) If inclined installation is used (inclination angle ≤ 15°): the immersion depth of the low-speed gear must be recalculated to ensure that the immersion depth of the tooth root is still 1/3~1/2 of the tooth height. Additional auxiliary equipment can be added to the side of the box
- How is the lubrication cycle of K67AM112-15.19-2.2KW gear reducer determined?The K67AM112-15.19-2.2KW gear reducer adopts a splash lubrication system. The determination of the lubrication cycle (oil change cycle) requires a comprehensive judgment based on three core factors: equipment design parameters, operating conditions, and lubricating oil performance. The core logic is to maintain the lubrication, heat dissipation, and cleaning capabilities of the lubricating oil through periodic oil changes, and avoid gear and bearing wear failures caused by oil deterioration and failure. The specific basis and method for determination are as follows: 1. Based on the basic cycle of equipment design parameters, the basic oil change cycle of this type of reducer can refer to the recommended value in the manufacturer's factory manual. Its design parameters determine the lubrication requirements under basic working conditions: 1. Power and speed characteristics: This model has a power of 2.2kW and a transmission ratio of 15.19. It is a small to medium power, medium and low speed reducer. The gear meshing impact is small and the lubricating oil deteriorates relatively slowly. Under ** rated working conditions (full load, continuous operation ≤8h/day, ambient temperature

According to JB/T 8853-2015 standard, it has a total of 5 assembly forms (Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ). The core difference lies in the input/ The position, rotation and installation orientation of the output shaft are as follows: 1. Assembly form I input shaft and output shaft are in the same direction (both on the same side of the reducer box), with the input shaft at the top and the output shaft at the bottom; installation method: horizontal foot installation (fixed base), the input shaft can be clockwise/counterclockwise (according to motor rotation); applicable scenarios: equipment with compact space and input and output that need to be arranged on the same side (such as small conveyors and mixers). 2. Assembly form Ⅱ input shaft and output shaft are reversed (separated on both sides of the box), the input shaft is on top, and the output shaft is on the bottom; installation method: horizontal foot installation, input shaft and output shaft rotate in opposite directions; applicable field
- What effect does the working environment temperature of ZL35-12-I gear reducer have on the motor power?The working environment temperature of the ZL35-12-I gear reducer mainly changes the effective output power of the motor indirectly or directly by affecting the motor heat dissipation efficiency and the performance of the reducer lubricating oil. The specific effects are as follows: 1. The impact of high temperature environment (ambient temperature > 45°C) on motor power 1. The heat dissipation efficiency of the motor decreases and the effective power attenuates. The rated power of the motor is based on the standard ambient temperature (25°C) Calibrated, when the ambient temperature exceeds 45°C, the temperature difference between the motor shell and the environment decreases, the heat dissipation speed slows down, and the winding temperature rises rapidly. In order to prevent the winding insulation layer from aging due to high temperature, the allowable output power of the motor will be forced to be reduced. (1) Empirical rule: for every 10°C increase in ambient temperature, the effective output power of the motor will decrease by 8% to 12%; when the temperature reaches 60°C, the power attenuation can reach 20% to 30%. (2) Impact on ZL35-12-Ⅰ
- How to adjust the meshing gap between the cycloidal wheel and the pin gear shell of the BLEY3922-5133-0.55KW reducerAdjust BLEY3922-5133-0.55kW The meshing gap between the cycloid wheel and the pin gear shell of the cycloidal pin wheel reducer is a key operation to ensure smooth transmission, reduce noise, and extend the service life. The standard range of the meshing gap of this model is 0.15~0.30mm. The specific adjustment steps are as follows: 1. Gap measurement and marking before disassembly. First, manually rotate the input shaft, feel the rotation resistance and record the abnormal position; then use a feeler gauge to measure the gap between the cycloidal wheel tooth top and the pin tooth pin, and mark the area where the gap is too large or too small to provide reference for subsequent adjustments. If the reducer has a double cycloid structure, alignment marks must be made on the two cycloid wheels, eccentric sleeve, and output flange to avoid assembly phase errors after disassembly and affecting the gap adjustment accuracy. 2. Disassemble the core components and clean and inspect them. Remove the motor, input shaft end cover, output flange, pin bushing and pins in sequence, and take out the two cycloid wheels. Please note that it is forbidden to knock the cycloidal wheel and pin teeth during disassembly.
- How to control the start, stop and operating load of the motor supporting the BLEY4527-595-4KW cycloidal reducerThe core of controlling the start, stop and operating load of the motor supporting the BLEY4527-595-4kW cycloidal pinwheel reducer is to match the motor characteristics and the working condition requirements of the reducer to avoid start-stop impact damage to transmission components and overload operation to shorten the life of the equipment. Specifically, precise control can be achieved through the three dimensions of electrical control, mechanical protection, and working condition optimization. The operation method is as follows: 1. Smooth control of motor start and stop (reduce impact load). The reducer has a reduction ratio of 595. It is a large reduction ratio and low-speed model. The instantaneous impact when the motor starts and stops will be amplified, which can easily cause the cycloid wheel and pin tooth pin to break. The following electrical and operating methods need to be used to buffer the impact: 1. Electrical control scheme (preferred) (1) Install a frequency converter for speed control starting with a matching 4kW motor. Use a general-purpose frequency converter (adaptive motor power ≥5.5kW to avoid overload), and set a soft start/ Soft stop parameters: Set the start time to 5~10s and stop
