Fang Yuan supports a new generation of products: drum tooth slewing ring

At present, most of the traditional slewing bearing gears are involute cylindrical spur gears. With the increasing requirements of customers on product bearing, service life and transmission efficiency, traditional cylindrical spur gears can no longer meet customer requirements.

Fang Yuan supports a new generation of products: drum tooth slewing ring

The researchers of Maanshan Fangyuan Slewing Ring Co., Ltd. have designed and developed rotary gear slewing bearings after many years of research and development according to the relevant host operating conditions. Drum-shaped slewing bearing is divided into outer gear type and inner gear type, and the ring gear teeth are all drum-shaped. Compared with the traditional cylindrical spur gear slewing ring, the slewing ring of the spur tooth has increased the transmission torque by more than 30%, and can withstand medium and heavy loads and impact loads. Because the teeth are drum-shaped, the meshing contact area is large and the contact stress is low. Therefore, it has long service life, smooth transmission, low noise, and transmission efficiency of 99.7%. At the same time, it can effectively eliminate the influence of angular displacement and avoid the tooth-to-edge phenomenon caused by stress concentration due to extrusion of the straight tooth edge. In addition, compared with the traditional spur type slewing ring, the use of the slewing ring is more reliable, easy to maintain, convenient assembly and disassembly, and the cost is greatly reduced.
At present, drum-shaped slewing bearings have been used in excavators, truck cranes, tower cranes and other types of construction machinery, and their product performance is stable and reliable.
The design and production of drum-shaped slewing bearings will push China's construction machinery parts industry to a new level. (This article comes from Fangyuan support)
