when you put your hands on pinion bearings, you can feel intermittent periodic impact.
(1) Caused by bending of rotary kiln (for rotary kin girth gear). Improve the temperature when starting kiln, and and the internal shock will be eliminated in a short time.
(2) Wear of connecting parts. Replace (or tighten) the connecting screws.
In order to ensure the machining quality and the durability of girth gear, CHAENG suggested that large manufacturers are much better when choosing girth gear manufacturers, because the requirements of girth gear accuracy / hardness / wear / stability are very high, experienced large manufacturers with good reputation, high credibility have the processing capacity, heat treatment technology and material selecting ability, to ensure the quality of girth gear for ball mill and rotary kiln.
CHAENG has its own large casting base, and employs the top talents of casting technology to serve as the senior manager and its technical team. Now, CHAENG casting base already has the comprehensive ability to provide users a series services from semi-finished products casting to finished products and a complete solution to the key assembly parts.2. Lubrication is an important maintenance measure to reduce the wear of girth gear, and save energy of production, then how to choose lubricants?
Answer:
(1) suitable viscosity and viscosity index.
(2) improve extreme pressure performance of oil film strength.
(3) excellent oxidation resistance.
(4) excellent rust resistance and moisture separation.
