How to improve the slewing bearing’s gear processing efficiency?

Slewing bearing is a kind of large bearing that runs at low speed and at the same time bear heavy load, usually with gears on the inner ring or outer ring, used to connect large parts that require relative rotation. It is widely used in construction machinery, wind power equipment, port machinery and other fields.

The gear machining process takes up a lot of time during the entire cycle from forging to finished product to delivery to the user, the length of the delivery period largely depends on the slewing bearing gear machining efficiency.

In recent years, due to the country’s strong investment in infrastructure, new energy equipment and other fields, the market demand for slewing bearings has also increased sharply and there is often a shortage of supply. On the other hand, there are many domestic slewing bearing manufacturers. They can minimize the cost while ensuring product quality, which is the key for the company to stand out in the fierce market competition.

Gear machining is the longest time-consuming process in the production of slewing bearings and it is also one of the most important factors that have restricted the production efficiency of slewing bearings. Traditional slewing bearing gear machining usually has two methods: gear shaping and gear hobbing. In order to meet the increasing requirements for machining accuracy and production efficiency, Gear hobbing and gear shaping technology is constantly developing towards full numerical control, high speed, high precision, intelligence, etc.

However, the processing efficiency is still not up to the ideal state, especially for the processing of internal gears, only gear shaper can be used. The cutting amount of each feed is small, the processing efficiency is low.

In recent years, a CNC high-speed gear milling method has been gradually promoted in the slewing bearing industry. There are two models of internal gear machines and external gear machines. The machining is based on the profiling principle, the machining efficiency is high and the feed rate is large.

It is suitable for large diameter slewing bearings and large modulus slewing bearing processing, especially internal gear machining, is 5-8 times more efficient than traditional gear shaping, which greatly shortens the of slewing bearing’s production cycle.

Gear milling, gear hobbing and gear shaping have their own advantages and disadvantages in terms of processing efficiency and equipment cost. In the case of sufficient market demand, the gear milling efficiency is better than gear hobbing and gear shaping, the gear milling cost is also lower than gear hobbing and gear shaping.
