Embodiment Construction

[0029] The implementation mode of the present invention is illustrated by specific specific examples below, and those who are familiar with this technology can easily understand other advantages and effects of the present invention from the contents disclosed in this description. Obviously, the described embodiments are a part of the present invention. , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] Refer to attached Figure 1-7 , a preload adjustable precision combined bearing provided by the present invention includes a bearing outer ring 1, a bearing inner ring 2 is coaxially arranged on the inner side of the bearing outer ring 1, and multiple bearings are arranged between the bearing outer ring 1 and the bearing inner ring 2. A ball 3, a plurality of balls 3 are distributed in a ...

Abstract

According to the technical scheme, the pretightening force adjustable precise combination bearing comprises a bearing outer ring, a bearing inner ring is coaxially arranged on the inner side of the bearing outer ring, a plurality of balls are arranged between the bearing outer ring and the bearing inner ring and distributed in a circumferential array mode, retainers are arranged on the two sides between the bearing outer ring and the bearing inner ring, and the retainers are arranged on the two sides between the bearing outer ring and the bearing inner ring. The precise combination bearing with the adjustable pretightening force has the beneficial effects that the pretightening adjusting mechanism is arranged, the adjusting bolt is limited through the locking nut, so that the spacing distance between the two retainers can be adjusted, and the pretightening force is adjusted through elastic extrusion of the first spring, so that the pretightening force is adjusted, and the precision of the pretightening force is improved. According to the retainer for the ball bearing, by arranging the arc-shaped plates, every two opposite arc-shaped plates can clamp the balls to different degrees, so that pre-tightening force adjustment is achieved, and the problems that the pre-tightening force of an existing retainer for the ball bearing is fixed during installation, adjustment cannot be conducted according to the sizes of the balls or actual situation needs, and use is inconvenient during combination and assembly are effectively solved.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a precision combined bearing with adjustable pretightening force. Background technique [0002] The general description of the pretightening force is: in the connection (connection methods and uses are diverse), before being subjected to the working load, in order to enhance the reliability and tightness of the connection, in order to prevent the connection between the connected parts after being loaded. Gap or pre-applied force relative to slippage. Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. [0003] When the existing ball bearings are installed, most of the internal balls are limited by the cage. The pre-tightening force of this method is fixed and cannot be adjusted according to the size of the balls or t...
