Abstract

The utility model relates to an irregular slide bearing for electrical installations, which is characterized in that: the irregular slide bearing consists of a movable ring and a static ring, wherein the static ring is a circular concave member, a through hole is formed on the concave surface, a shielding slab is formed on the circumference, a rabbet is formed on the end face of the movable ring, an oil groove is formed on the external circumference face, a square hole is formed in the center of the movable ring, and the movable ring is arranged in the concave part of the static ring. The utility model has the advantages of simple structure, easy manufacture, high precision, adaptation to various square shafts, high production efficiency, low cost, convenient assembly and maintenance.

Description

Special-shaped sliding bearing

Technical field

The utility model relates to bearing, is applied to a kind of special-shaped sliding bearing on the electrical installations specifically.

Background technique

Bearing is an indispensable supporting member in the shaft drive, and it is directly connected to axle output transmission effect, and electrical installations overall work quality.The transmission shaft of present most electrical installationss all is to adopt driving torque big, the square shaft that transmission is effective, as clapping type contactor, air-break switch, on-load switch, cam controller etc. all is to adopt the square shaft transmission, and its bearing is employing standard rolling bearing or circle shell type sliding bearing.Owing to adopt these two kinds of bearings, bring a lot of deficiencys for manufacturing, maintenance, the cost of electrical installations:

1. behind the drive shaft body single forming, secondary deformation processing also must be carried out in axle two supports position, and requires to guarantee the higher size and the precision of position, causes transmission shaft processing technology difficulty to increase, and manufacturing efficiency is low.

2. bearing and rack will adopt fixed connecting piece and corresponding technological measure to realize, the bothersome effort of assembling and maintenance.

3. complex manufacturing and rolling bearing price height cause the product cost height.

The model utility content

The purpose of this utility model provides a kind of special-shaped sliding bearing, it is simple in structure, precision is high, it is easy to maintenance to make assembling, has overcome the many deficiencys that adopt standard rolling bearing and circle shell type sliding bearing to bring for manufacturing, maintenance, the cost of electrical installations.

The purpose of this utility model is achieved in that and it is characterized in that: be made up of rotating ring and stationary ring, stationary ring is a round concave shape spare, be processed with through hole on the concave surface, be processed with the retaining platform on the circumference, be processed with seam on the rotating ring end face, be processed with on the outer peripheral surface and contain oil groove, the center is processed with square hole, and rotating ring is assemblied in the spill of stationary ring.

The utility model has the advantages that:

1. simple in structure, easily manufactured, the precision height.

2. can be applicable to various square square shafts, and can simplify and be connected technology and transmission shaft with rack

Processing technology improves transmission accuracy.

3. can adopt single forming technology, manufacturing efficiency is improved, cost reduces, and assembles easy to maintenance.

Description of drawings

Fig. 1 is a kind of embodiment's of the utility model a structural representation.

Fig. 2 is along the sectional view of A-A line among Fig. 1.

Fig. 3 is the stationary ring structural representation.

Fig. 4 is the rotating ring structural representation.

Embodiment

Referring to Fig. 1-Fig. 4,1 is stationary ring in the utility model accompanying drawing, the 2nd, and rotating ring, stationary ring 1 and rotating ring 2 all can adopt powdered metallurgical material and engineering plastics, use single forming technology and make.Stationary ring 1 is a round concave shape spare, be processed with through hole 1A on the concave surface, be processed with retaining platform 1B on the excircle, rotating ring 2 is assemblied in the spill of stationary ring 1, be processed with seam 2B on its end face, be processed with on the circumferential surface and contain oil groove 2C, contain oil groove 2C during assembling and contain lubricant oil, the center is processed with square hole 2A, the corresponding cooperation with transmission shaft of square hole 2A.During work, stationary ring 1 is assemblied in the axis hole of frame, and retaining platform 1B plays the axially locating effect, and rotating ring 2 supporting drive shafts rotate synchronously with axle in stationary ring 1 spill.

Claims

1, a kind of special-shaped sliding bearing, feature is: be made up of rotating ring and stationary ring, stationary ring is a round concave shape spare, be processed with through hole on the concave surface, be processed with the retaining platform on the circumference, be processed with seam on the rotating ring end face, be processed with on the outer peripheral surface and contain oil groove, the center is processed with square hole, and rotating ring is assemblied in the spill of stationary ring.
