Abstract
The invention relates to a novel nylon bracket with controllable sagging amount, belonging to the centripetal cylindrical roller bearing retaining bracket and aiming at solving the problem that the sagging amount and the locking amount of the traditional nylon retaining bracket are not easy to control. The pocket holes of the novel nylon bracket are connected by circular arcs, oblique lines and straight lines instead of circular arcs and oblique lines. The conflict between the sagging amount and the locking amount is thoroughly solved due to the change of the shape of the locking points of the pocket holes. A bearing rotates flexibly and is convenient to install, and the sagging amount of the novel nylon bracket is controlled.
Description
Technical field
The invention belongs to technical field of bearings, the particularly a kind of novel nylon bracket that can control sag of chain is mainly used in motor, air compressor screw rod industry.
Background technique
At present, customer requirements when installation inner ring and the axle outer ring of will packing into smoothly, promptly require retainer that the sag of chain requirement is arranged, the most of copper cage that adopts of retainer of sag of chain requirement is generally arranged, and the pocket hole guarantees by machining, the bad control of nylon bracket sag of chain, because of roller will be installed in the retainer through the pocket hole, hold depth is little, and is easy to assembly, but sag of chain is big; When the control sag of chain, hold depth must strengthen, and both are contradiction very, is badly in need of a kind of roller of both easily having adorned of design, and the retainer that sag of chain is again little is satisfied the demand.
Summary of the invention
At above deficiency, the objective of the invention is to propose a kind of novel nylon bracket that can control sag of chain, both adorned roller easily, sag of chain is again little.
Technological scheme of the present invention is: nylon cages 3 pocket bore portions change circular arc, oblique line, straight line connection into by traditional circular arc, straight line.Circular arc is nylon cages 3 pocket hole circle arcs; Oblique line is pocket hole and fore shaft transition straight line, and is tangent with the pocket hole; Straight line is a fore shaft.The change of lock point place, pocket hole shape has thoroughly solved the contradiction of sag of chain and hold depth.The bearing revolution is easy to assembly flexibly, promptly guarantees to turn round to have controlled sag of chain flexibly again.
The invention has the beneficial effects as follows: the change of pocket hole lock point place shape has thoroughly solved the contradiction of sag of chain and hold depth.The bearing revolution is easy to assembly flexibly, promptly guarantees to turn round to have controlled sag of chain flexibly again.And the nylon bracket cost after improving does not increase.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the present invention is elaborated:
Fig. 1 is an entad roller bearing structure assembling schematic representation of band nylon bracket;
Wherein, 1, the outer ring, 2, roller, 3, nylon cages, 4, inner ring.
Fig. 2 is a conventional nylon retainer structural representation;
Fig. 3 is this novel nylon retainer structural representation.
Embodiment
As shown in Figure 1, this bearing is made up of outer ring 1, roller 2, nylon cages 3 and inner ring 4.The present invention be directed to the improvement that nylon cages 3 is done.As Fig. 2,3, nylon cages 3 pocket bore portions change circular arc shown in Figure 3, oblique line, straight line connection into by traditional circular arc, straight line shown in Figure 2.Circular arc is nylon cages 3 pocket hole circle arcs; Oblique line is pocket hole and fore shaft transition straight line, and is tangent with the pocket hole; Straight line is a fore shaft.
Claims (1)
1. can control the novel nylon bracket of sag of chain, it is characterized in that, nylon cages (3) pocket bore portion is circular arc, oblique line, straight line connection; Described circular arc is nylon cages (a 3) pocket hole circle arc, and described oblique line is the transition straight line of pocket hole circle arc and fore shaft, and tangent with pocket hole circle arc, and described straight line is a fore shaft.
