Abstract
The embodiment of the invention discloses a multi-wedge-tooth bearing with a radial flange, which is applied to an elevator without a machine room. The multi-wedge-tooth bearing at least comprises an outer ring, an inner ring and a rolling body which is arranged between the outer ring and the inner ring, wherein the outer circumferential surface of the outer ring is provided with a plurality of parallel V-shaped teeth which can be matched with a toothed steel band of an elevator tractor, the left side and the right side of the outer surface of the outer ring are axially and respectively provided with a left flange and a right flange protruded outwards in the radial direction, the plurality of parallel V-shaped teeth are arranged between the left flange and the right flange, the left flange, the plurality of parallel V-shaped teeth and the right flange are collectively encircled to form a steel band drop-proof structure, and when the outer ring is matched with the toothed steel band, one surface, opposite to the toothed steel band, of the left flange and the right flange at least partially pushes against the toothed steel band. By adopting the multi-wedge-tooth bearing with the radial flange, the toothed steel band can be effectively prevented from dropping off from the bearing outer ring in the rotation process, so that more safety and reliability can be realized. In addition, the parallel V-shaped teeth on the outer ring can be protected, and the damage probability of the parallel V-shaped teeth on the outer ring of the bearing can be reduced.
Description
Technical field:
The present invention relates to a kind of many wedges tooth bearing with radial flange, especially a kind of many wedges tooth bearing of the band radial flange be applied on Machine room-less elevator.
Background technique:
The existing many wedges tooth bearing be applied on Machine room-less elevator, as shown in Figure 1, its rolling element 03 generally comprising outer ring 01, inner ring 02 and be located between outer ring 01 and inner ring 02, the outer circumferential face of described outer ring 01 is provided with the some parallel V-type tooth 011 that can match with the profile of tooth steel band of lift machine.In use, some parallel V-type teeth are identical with the profile of tooth steel band of lift machine, steadily contact, larger surface of contact and less occupy-place volume is had than traditional traction steel-cable formula belt wheel, effectively can improve transmission efficiency, can eliminate when dragging elevator cab lifting and rock and noise, energy-conserving and environment-protective.But there is following defect in it: 1, can not effectively prevent profile of tooth steel band from coming off from bearing outer ring in operation process.2, in Production of bearing flow process, parallel V-type tooth on outer ring cannot be reduced by the probability of gouge.
Summary of the invention:
For overcoming the problem that existing many wedges tooth bearing can not effectively prevent profile of tooth steel band from coming off from bearing outer ring in operation process, embodiments provide a kind of many wedges tooth bearing of the band radial flange be applied on Machine room-less elevator.
A kind of many wedges tooth bearing with radial flange, be applied on Machine room-less elevator, it at least comprises outer ring, inner ring, and the rolling element be located between outer ring and inner ring, the outer circumferential face of described outer ring is provided with the some parallel V-type tooth that can match with the profile of tooth steel band of lift machine, on the outer surface of described outer ring, in its axial left and right sides, radially outward is convexly equipped with left flange and right flange respectively, described some parallel V-type teeth are located between left flange and right flange, left flange, some parallel V-type teeth, and between right flange, jointly surround profile of tooth steel band disconnecting prevention structure, and outer ring is when mating with profile of tooth steel band, its left flange and one side relative with profile of tooth steel band in right flange at least partly and profile of tooth steel band offset.
The embodiment of the present invention, by arranging left flange and right flange on the outer surface of outer ring, make jointly to surround profile of tooth steel band disconnecting prevention structure between left flange, some parallel V-type teeth and right flange, can effectively prevent profile of tooth steel band from coming off from bearing outer ring in operation process; And outer ring is when mating with profile of tooth steel band, its left flange and one side relative with profile of tooth steel band in right flange at least partly and profile of tooth steel band offset, increase the area of contact of profile of tooth steel band disconnecting prevention structure and profile of tooth steel band, reduce the possibility that profile of tooth steel band comes off further, more safe and reliable.In addition; the setting of described left flange and right flange; also can protect the parallel V-type tooth on outer ring; in Production of bearing flow process; even if collide along the adjacent bearing of production line conveying; this collision is also only confined to, between the flange of adjacent bearing, can not injure parallel V-type tooth, thus the parallel V-type tooth that can reduce on bearing outer ring is by the probability of gouge.

Embodiment:
In order to make technical problem solved by the invention, technological scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Embodiment one: as Fig. 2, shown in Fig. 3, a kind of many wedges tooth bearing with radial flange, be applied on Machine room-less elevator, it at least comprises outer ring 1, inner ring 2, and the rolling element 3 be located between outer ring 1 and inner ring 2, the outer circumferential face of described outer ring 1 is provided with the some parallel V-type tooth 11 that can match with the profile of tooth steel band 4 of lift machine, on the outer surface of described outer ring 1, in its axial left and right sides, radially outward is convexly equipped with left flange 12 and right flange 13 respectively, described some parallel V-type teeth 11 are located between left flange 12 and right flange 13, left flange 12, some parallel V-type teeth 11, and jointly surround profile of tooth steel band disconnecting prevention structure between right flange 13, and outer ring 1 is when mating with profile of tooth steel band 4, its left flange 12 and one side relative with profile of tooth steel band 4 in right flange 13 at least partly and profile of tooth steel band 4 offset.
The embodiment of the present invention, by arranging left flange 12 and right flange 13 on the outer surface of outer ring 1, make jointly to surround profile of tooth steel band disconnecting prevention structure between left flange 12, some parallel V-type teeth 11 and right flange 13, can effectively prevent profile of tooth steel band 4 from coming off from bearing outer ring in operation process; And outer ring 1 is when mating with profile of tooth steel band 4, its left flange 12 and one side relative with profile of tooth steel band 4 in right flange 13 at least partly and profile of tooth steel band 4 offset, increase the area of contact of profile of tooth steel band disconnecting prevention structure and profile of tooth steel band 4, the possibility that further reduction profile of tooth steel band 4 comes off, more safe and reliable.In addition; the setting of described left flange 12 and right flange 13; also can protect the parallel V-type tooth 11 on outer ring 1; in Production of bearing flow process; even if collide along the adjacent bearing of production line conveying; this collision is also only confined to, between the flange of adjacent bearing, can not injure parallel V-type tooth 11, thus the parallel V-type tooth 11 that can reduce on bearing outer ring is by the probability of gouge.
Further, the sectional shape radially outward of described profile of tooth steel band disconnecting prevention structure is by large gradually little.Further profile of tooth steel band 4 can be limited between left flange 12 and right flange 13, prevent profile of tooth steel band 4 from coming off from bearing outer ring 1 in operation process, improve Security.
