From December 15th, 2015 to January 6th, 2016, Wilt Company carried out maintenance work on KMP710 vertical grinding reducer for a group company.

The reducer was put into use in 2004. In 2011, the domestically produced high-speed shaft and spiral bevel gear were used for the maintenance of the reducer. In August 2015, the high-speed pinion was damaged. Therefore, Wilt was commissioned to do the whole machine maintenance service.

After disassembling the reducer, it was found that the pinion has three teeth broken. From the current situation of the fracture, the possible reason may be that the pinion material defect or the material strength cannot meet the working condition requirements. And the spiral bevel gear used in 2011 is very different from the Flemish original. The Ø44 bolt hole of the spiral bevel gear flange is expanded to Ø45, which is not interchangeable. This problem brings great difficulties and uncertainties to the maintenance work without pre-preparation. After analyzing and comparing the Wilt reducer maintenance technicians, the solution of re-boring on the flange was selected to successfully solve this problem.

On January 8, 2016, the reducer was installed and operated smoothly at the customer site. Wilt arranged the vibration reducer maintenance professional to carry out the vibration spectrum test, and all the performance indicators are very superior.

The industrial reducer is a function of matching the rotational speed and transmitting torque between the prime mover and the actuator. It is a reduction transmission device and is widely used in mechanical equipment. The hardened surface reducer has been in use for a long time. Usually, abnormal sounds are generated during the use process. After opening the hardened surface reduction casing, it is found that there are different programs in the pinion teeth. The teeth of the large gear also have a certain degree of tooth edge. Damage, the reason for the damage is that the bearing steel ball is broken due to overload, and the bearing residue falls into the gear gap and causes the gear to bite. Reducer maintenance - please find Wilt Gear Wilt Gear (Nanjing) Co., Ltd.
