Abstract
The utility model relates to a bearing, in particular to a quick-assembly needle roller bearing for a starting motor. The needle roller bearing with the requirement for location assembly in relative to a bearing base hole comprises a double-retaining-edge outer ring, a recessed and/or protruding location structure on the surface of the outer circle of the double-retaining-edge outer ring and matched with the bearing base hole, and at least one location groove or location bump uniformly distributed at the circumference of the inner circle of one retaining edge of the double-retaining-edge outer ring. The quick-assembly needle roller bearing solves the problem of quick assembly of a bearing with location assembly requirement, and a user can quickly find the location part during assembly, thereby improving the assembly speed, the assembly efficiency and the mounting accuracy.
Description
Technical field
The utility model relates to a kind of bearing, and the actuating motor needle bearing of the energy quick mounting of location matching requirements is arranged between particularly a kind of and bearing saddle bore.
Background technique
Some bearings are arranged for reaching and reasons such as bearing saddle bore reliably is connected, there are some concaveconvex structures to match in the outer ring of bearing surface design with corresponding structure on the bearing saddle bore inner headed face, so that bearing is connected with bearing saddle bore reliably, prevents to become flexible, axially locating is more accurate.For ease of assembling, those concaveconvex structures generally do not adopt ring-type, and the problem that just has a location to assemble between bearing and bearing saddle bore has like this increased the difficulty of Bearing Installation; Efficiency of assembling is low, and installation precision is not high.
The model utility content
The technical problems to be solved in the utility model is: the quick mounting problem that solves the bearing that the location matching requirements are arranged, the utility model provides a kind of actuating motor needle bearing of energy quick mounting, the client is in the installation process, can find position point fast, the effect that improves efficiency of assembling and improve installation precision is played in assembling fast.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of actuating motor needle bearing of energy quick mounting, has two ribs outer ring, the outer round surface of two ribs outer ring has position structure depression and/or projection, that match with bearing saddle bore, has at least one positioning groove or the positioning convex of circumference uniform distribution on the inner headed face of a wherein rib of two ribs outer ring.The client can pass through positioning groove or positioning convex in the installation process, find position point fast, the assembly fixture quick identification is to positioning groove or positioning convex on production line, the location assembles automatically apace, has improved efficiency of assembling and installation precision.
For further improving efficiency of assembling and installation precision, described positioning groove or positioning convex are three～five.
For ease of making, described positioning groove is the semicircular arc positioning groove; Described positioning convex semicircular arc positioning convex.
The beneficial effects of the utility model are, the actuating motor needle bearing of energy quick mounting of the present utility model, solved the quick mounting problem of the bearing that the location matching requirements are arranged, the client is in the installation process, can find position point fast, assembling has improved efficiency of assembling and installation precision fast.
