1. Inspection of forging blanks First understand the material of the blank and the state after forging before processing. Secondly, it is necessary to check whether the blank has defects such as lamination and cracks. Measure the dimensions of the blank. Including the inner and outer diameter of the blank, the height dimension, calculating the […]
Definition and operation principle of crossed cylindrical roller slewing bearing Definition: Cross-roller type slewing bearing consists of two races. It is compact in structure, light in weight, high in manufacturing precision, small in assembly clearance, high in installation accuracy, and 1:1 cross-arrangement of rollers. The force, tipping moment and large radial force are widely used […]
With the advancement of technology, the application of slewing bearings in construction machinery is more and more extensive. If we find that the slewing bearing can’t move, how can we deal with it? The following methods can help you to eliminate this problem. 1. The newly purchased products are not flexible. Please check the production […]
1. Which carriers use slewing rings to operate in high temperature environments The slewing bearing of the ladle turret has a relatively poor working condition and is subject to high axial load and overturning moment. These loads are transmitted and received by the ring gear, the raceway of the raceway and the gear, so the […]
Slewing bearings are a common mechanical part in industrial equipment. They have many good properties and advantages that can increase productivity in industrial production. However, in the long-term use of the slewing bearing, various failures will inevitably occur. The methods for solving various failures are as follows: 1.
