There is a certain gap between the inner ring, the outer ring and the rolling elements of the rolling bearing, so there may be a relative displacement between the inner ring and the outer ring.When there is no load, one ring is fixed and the other ring moves radially from one limit section to the other limit Read More

The gear reducer can rotate, but the operating current exceeds the rated value, which is called overload.The basic reflection of the overload of the reducer is: although the current exceeds the rated value, the extent of the excess is not large, and usually does not generate a large inrush current.If the gear reducer is overloaded, we need to find out the cause of its overload, and then use the correct method to solve the overload problem of the gear reducer.Analysis of the specific reasons for the overload of the gear reducer: 1. The mechanical load is heavy, and the specific characteristic of the heavy load is that the motor generates heat, which can be found by reading the operating current from the display.2. The three-phase voltage is unbalanced, causing the operating current of a certain phase to be too large, resulting in an overload trip. The characteristic is that the gear reducer generates heat unbalanced. phase current).3. Misoperation, the current detection part inside the inverter fails, and the detected current signal is too large, causing tripping.gear Read More

For the maintenance of improper gear meshing of the geared motor, first of all, try to use the pinion bearing for adjustment.Check whether the center distance is correct, and whether the large gear shaft is parallel to the pinion shaft.If it is found that the axes are not parallel or the center distance is not consistent with the parameter display, the bearing should be adjusted to adjust the found defects.If the bearings are installed correctly, the meshing of the reducer can be repaired by grinding.If the contact surface of the tooth is not suitable, scraping and grinding must be carried out first.Scraping and grinding is to reduce the grinding time, but the scraping and grinding work requires skilled fitters.Apply a thin layer of red lead oil on both sides of the teeth of the small gear, and then turn the large gear forward and backward for a week or two. The places with red lead oil marks on the teeth of the large gear need to be scraped. The red lead oil imprint exceeds the cut-off of 50~55% of the tooth length.To further improve the meshing condition of the teeth, the grinding method must be used.When grinding, the peripheral speed of the large gear should be 2~2.5 feet per second, and the load machine should be unloaded Read More

1. Rolling bearing assembly is unreasonable, and the fit tolerance is too tight or too loose. degree, the fit chosen and its correct assembly.Usually, in a horizontal motor, a well-assembled rolling bearing only bears radial stress, but if the fit between the inner ring of the bearing and the shaft is too tight, or the fit between the outer ring of the bearing and the end cover is too tight, that is, when the tolerance is too large, then after assembly The bearing clearance will become too small, sometimes even close to zero.In this way, the rotation is not flexible, and it will generate heat during operation.If the fit between the bearing inner ring and the shaft is too loose, or the bearing outer ring and the end cover are too loose, then the bearing inner ring and the shaft, or the bearing outer ring and the end cover, will rotate relative to each other, resulting in friction and heat, resulting in bearing failure. overheat.Usually, the tolerance zone of the inner diameter of the bearing inner ring as the reference part is moved below the zero line in the standard, which is beneficial to the same Read More

Whether it is a military enterprise or a general civilian enterprise, they will use various machines in the process of producing products, and the reducer is one of them.When using a reducer, it is better to match the motor frequency to produce the product.In many reducers, many manufacturers will Read More
