Abstract
The utility model relates to a special-shaped bearing, which is characterized in that the utility model is composed of a stationary ring and a moving ring, wherein, the stationary ring is a circular concave member; a through hole is processed on a concave surface; the moving ring is assembled in the concave part of the stationary ring; the center position of a moving ring is provided with a special-shaped shaft hole. The utility model has the advantages of simple structure, convenient manufacture, high precision high productive efficiency low cost and convenient assembly and maintenance, and is suitable for various truncated special-shaped transmission shafts.
Description
The utility model relates to bearing, specifically is used for a kind of Special-shaped bearing of electrical installations.
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, i.e. special-shaped axis.Clapping type contactor, air-break switch, on-load switch, cam controller etc. all are to adopt abnormity side to take out 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 also for manufacturing, maintenance, the cost of electrical installations:
1, behind the axis body single forming, secondary deformation processing also must be carried out in an axle two supports position, and will guarantee the precision of size and position, causes that the axis processing technique difficulty is big, manufacturing efficiency is low.
2, bearing and rack will adopt fixed connecting piece and corresponding technological measure to realize that assembling and maintenance are wasted time and energy.
3, complex manufacturing and rolling bearing valency height cause the product cost height.
The purpose of this utility model provide a kind of simple in structure, precision is high, make assembling Special-shaped bearing easy to maintenance.
The purpose of this utility model is achieved in that and it is characterized in that being made up of stationary ring and rotating ring that stationary ring is the round concave shape companion, is processed with through hole on the concave surface, and rotating ring is assemblied in the spill of stationary ring, and the rotating ring center is shaped on special-shaped axis hole.
Be processed with the retaining platform on the stationary ring excircle, be processed with seam on the rotating ring end face.
The utility model has the advantages that:
1, simple in structure, easily manufactured, the precision height.
2, can be applicable to the special-shaped transmission shaft of various sections shapes, and can simplify with rack and be connected technology and transmission shaft processing technology, improve transmission accuracy.
3, can adopt the once-through processing technology, the manufacturing efficiency height, cost is low, assembles easy to maintenance.
The utility model is described in further detail below in conjunction with accompanying drawing.
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 along the sectional view of B-B line among Fig. 3.
Fig. 5 is the rotating ring structural representation.
Fig. 6 is along the sectional view of C-C line among Fig. 5.
Referring to Fig. 1-6,1st, stationary ring of the present utility model, the 2nd, rotating ring of the present utility model, stationary ring 1 and rotating ring 2 can adopt high-strength engineering plastic, use the one-shot forming technique manufacturing and finish.Stationary ring 1 is a round concave shape spare, is processed with through hole 1a on the concave surface, is processed with retaining platform 1b on the excircle, and stationary ring 1 is assemblied on the axis hole of frame, and retaining platform 1b plays the axially locating effect.Rotating ring 2 is assemblied in the spill of stationary ring 1, is processed with seam 2b on its end face, and the center is processed with special-shaped axis hole 2a, and special-shaped axis hole 2a takes out the corresponding cooperation of odd-shaped cross section with transmission, and rotating ring 2 supporting drive shafts rotate synchronously with axle in stationary ring 1 spill during work.
Claims (2)
1, a kind of Special-shaped bearing is characterized in that being made up of stationary ring and rotating ring, and stationary ring is processed with through hole for solid female part on the concave surface, and rotating ring is assemblied in the spill of stationary ring, and the rotating ring center is shaped on special-shaped axis hole.
2, Special-shaped bearing according to claim 1 is characterized in that: be processed with the retaining platform on the stationary ring excircle, be processed with seam on the rotating ring end face.
