Description

Technical Field

[0001] The utility model relates to the technical field of speed reducer processing, in particular to a speed reducer gear surface grinding device. Background Art

[0002] Reducer gear is a kind of mechanical transmission device, which is mainly used to slow down the rotation speed of high-speed rotating motors or engines to the required speed to meet the needs of mechanical equipment. It is mainly composed of gears, bearings, sealing devices and other components, and can be divided into two types: single-stage reducer and multi-stage reducer. Different types of reducer gears are suitable for different industrial fields. In industrial fields such as power generation, steel, petrochemical, etc., they are often used to slow down the speed of shaft-driven devices. In the construction of infrastructure such as subways, roads, bridges, etc., reducer gears also play an important role, which can output torque and convert speed. In the prior art, when grinding the reducer gear, the gear is limited only by a limit rod. During grinding, the gear may move axially, affecting the grinding progress. In addition, when collecting the debris, it is difficult to screen the debris according to the specifications, which makes the subsequent recovery of the debris inconvenient.

[0003] In order to solve the above problems, the prior art patent number CN219725640U discloses a grinding device for processing reducer gears, which can achieve the effect of facilitating the rapid grinding of reducer gears during use, effectively limit the gears during the grinding process, and can screen and collect the debris generated by grinding, making subsequent debris recovery more convenient. However, the prior art still has shortcomings in actual use. When grinding the reducer gears, the effect of clamping and fixing the gears is usually weak, which makes it easy to offset during grinding, reduces the stability of the gears when being ground, reduces the grinding quality, and easily causes gear damage, thereby reducing work efficiency and extending working time. If the gears are displaced, it may not only damage the grinding equipment, but also pose a safety threat to the operator, thereby increasing the danger of grinding gears. Utility Model Content
