Description

Bearing convenient to change inner shaft sleeve

Technical Field

The utility model relates to a bearing technical field specifically is a bearing convenient to change inner shaft cover.

Background

The bearing is an important part in the modern mechanical equipment. Its main function is to support the mechanical rotator, reduce the friction coefficient in its motion process and ensure its rotation precision. It should be a support in terms of its function, i.e. literally explained for bearing the shaft, but this is only a part of its function, the support being essentially capable of taking up radial loads. It is also understood that it is intended to fix the shaft. The bearing is fast, easy and excellent, and automatic selection is recorded. That is, the shaft is fixed so that it can only rotate, but controls its axial and radial movements. The motor cannot work at all without a bearing. Because the shaft may move in any direction, the motor requires only rotation of the shaft when operating. In order to reduce the influence, good lubrication must be realized on the bearings of the high-speed shaft, some bearings are already lubricated and are called pre-lubricated bearings, and most bearings must be provided with lubricating oil, so that the bearings are not only increased in energy consumption due to friction during high-speed operation, but also easily damaged. The statement that sliding friction is converted to rolling friction is one-sided because there is something called a sliding bearing.

Most of the conventional bearings can only be adapted to the shaft core of one specification, and have poor compatibility, and the bearings cannot be reused on other equipment without being damaged, thereby causing waste.
