A composite bearing

Abstract

The invention relates to a combined bearing. The combined bearing comprises a bearing body. An annular cover plate and a closed cover plate are correspondingly arranged at the upper end and the lowerend of the bearing body in a detachable manner. By the adoption of the combined bearing, the problems that in the using process of an existing linear bearing, a common linear bearing in the existing market is a standard part, when the length of the motion track exceeds the motion range of the linear bearing, a plurality of linear bearings need to be installed in a side-by-side manner and cooperatively used, a plurality of bearings need to be fixed, the operation is complex, the installation positions of the linear bearings cannot be accurately controlled, the error exists, and the stability ofthe use of the linear bearings is influenced are solved; and the upper portion and the lower portion of the existing linear bearing are of an opening structure and cannot be used in a deformed mannerin use, the structure of an upper end cover of the bearing cannot be replaced, when one end of the bearing needs to be sealed in use, the bearing needs to be fixed by other parts by the working personnel, and the applicability is poor.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a combined bearing. Background technique [0002] Linear bearing is a kind of linear motion system, which is used in conjunction with a cylindrical shaft for linear travel. Linear bearings are widely used in sliding parts of industrial machinery such as precision machine tools, textile machinery, food packaging machinery, and printing machinery. [0003] However, the following problems exist in the use of existing linear bearings. a. The common linear bearings in the existing market are all standard components. When the length of the motion track exceeds the range of motion of the linear bearing, multiple linear bearings need to be installed side by side. In use, multiple bearings need to be fixed separately, the operation is complicated, and the installation position of the linear bearing cannot be accurately controlled, and there is an error, which affects the stability of the...

Problems solved by technology

[0003] However, the following problems exist in the use of existing linear bearings. a. The common linear bearings in the existing market are all standard components. When the length of the motion track exceeds the range of motion of the linear bearing, multiple linear bearings need to be installed side by side. In use, multiple bearings need to be fixed separately, the operation is complicated, and the installation position of the linear bearing cannot be accurately controlled. There is an error, which affects the stability of the linear bearing.

b. The upper and lower sides of the existing linear bearings have an open structure, which cannot be deformed during use, and the structure of the upper end cover of the bearing cannot be replaced. When one end of the bearing needs to be sealed during use, the staff needs to use other parts to fix it. Applicable poor sex

[0004] For the technical problems existing in the use of bearings, personnel in the related technical fields have made adaptation improvements after research, such as patent No. 2018212786216, a combination bearing improves the accuracy of bearing rotation, but for the above-mentioned The problems existing in the use of the mentioned existing linear bearings need to be solved urgently
