CN202280740U - Bearing ring capable of limiting pin roller - Google Patents

Abstract

The utility model discloses a bearing ring capable of limiting a pin roller. A pin roller is contained in a limiting containing hole of a bearing ring body; the peripheral side of the limiting containing hole is deformed to form a limiting part capable of preventing the pin roller from separating out; therefore, the pin roller can be prevented from separating out even if the bearing ring body does not need to use other materials or structures so as to lower production and material cost; the bearing ring capable of limiting the pin roller is cooperated with other mechanisms to be assembled and used to avoid the situation that the pin roller is separated out, and the use convenience is improved.

Description

Can place restrictions on the bearer ring of roller

Technical field

The utility model relates to a kind of bearing, particularly relates to a kind of bearer ring of placing restrictions on roller.

Background technique

The roller bearing 10 of convention, as shown in Figure 1, normally constitute by 13 of a plurality of rollers of clamping between interior ring 11 and one outer shroud 12; And its normally in this ring offer a plurality of appearances hole 111 on 11 and supply those rollers 13 ccontaining, those hold the effect that does not place restrictions on for those rollers 13 in holes 111, therefore must organize by outer shroud 12 covers and in this, place restrictions on deviating from of roller 13 outside the ring 11; Even, except interior ring 11 and outer shroud 12, also can use a kind of retainer of roller 13; By roller 13 is positioned earlier behind this retainer again with this in ring 11 and outer shroud 12 assemblings, hence one can see that, for positioning roller 13 certainly will need in the cooperating of ring 11 and outer shroud 12; Or even cooperate retainer to use again, and also more need special tool just can assemble during assembling, simultaneously; Because roller 13 is not placed restrictions on during assembling, therefore also have roller 13 and come off, assemble the problem that is difficult for easily, in view of this; This creator conceives with great concentration and more further investigation, creates a kind of bearer ring of placing restrictions on roller finally.

The model utility content

The utility model technical problem to be solved provides a kind of bearer ring of placing restrictions on roller, its main purpose be by the material deformation of bearing ring body itself in order to place restrictions on roller, reduce production costs and promote convenience of use.

For solving the problems of the technologies described above, a kind of bearer ring of placing restrictions on roller of the utility model holds pore volume by placing restrictions on the bearing ring body and puts a plurality of rollers; Wherein, this bearing ring body is the loop configuration with relative an inner ring surface and an outer ring surface, a plurality of placing restrictions on is set on this bearing ring body at interval holds the hole; This is placed restrictions on and holds the hole and have to place restrictions in this inner ring surface and hold mouthful, and this is placed restrictions on and holds the hole and have a device in this outer ring surface and hold mouthful, and this device holds mouth and has a device appearance bore; This is placed restrictions on the appearance mouth and has the appearance of placing restrictions on bore, and this device holds bore and places restrictions on the appearance bore greater than this, and this each roller has a roller diameter; This roller diameter is placed restrictions on the appearance bore less than this device holds bore greater than this, and this roller is placed in this and places restrictions on and hold in the hole, and receives this to place restrictions on to hold and mouthful place restrictions on; And should each install the portion that places restrictions in both sides week integrally formed respectively one that holds mouth; This is placed restrictions on portion and places restrictions on to hold in the hole towards this and protrude out, and makes this two place restrictions on and form one between the portion and place restrictions on through hole, and this is placed restrictions on through hole and has the through hole of placing restrictions on footpath; This places restrictions on the through hole footpath roller diameter less than this roller, and this bearing ring body is connect by this outer ring surface and faces this each stop portion and do not form a depressed part.

The utility model roller by the integrally formed portion of placing restrictions on of bearing ring body and is deviate from; Can reduce and produce and cost of material; And when cooperating other mechanisms to use behind the positioning roller of bearing ring body own again, just can not produce the situation that roller is deviate from, promote the convenience of using.

Embodiment

The utility model can be placed restrictions on the preferred embodiment of bearer ring of roller shown in Fig. 2, Fig. 3 a, Fig. 3 b, and it is to place restrictions on 30 of a plurality of rollers by a bearing ring body 20 to constitute, wherein:

This bearing ring body 20 is a loop configuration; And this bearing ring body 20 has a relative inner ring surface 21 and an outer ring surface 22, a plurality of placing restrictions on is set at interval on this bearing ring body 20 holds holes 23, and this is placed restrictions on and holds hole 23 and have to place restrictions in this inner ring surface 21 and hold mouthfuls 231; This is placed restrictions on appearance hole 23 and has a device appearance mouth 232 in this outer ring surface 22; This device holds mouthfuls 232 to have a device and holds bore D1, and this is placed restrictions on and holds mouthfuls 23 and have to place restrictions on and hold bore D2, and this device holds bore D1 and places restrictions on appearance bore D2 greater than this; And this each roller 30 has a roller diameter D3; This roller diameter D3 places restrictions on greater than this less than this device holds bore D1 and holds bore D2, and then this each roller 30 just can hold mouthfuls 232 by this device and receive into this and place restrictions on and hold in the hole 23, and receives this and place restrictions on and hold placing restrictions on of mouth 231; And this bearing ring body 20 is placed restrictions on portion 24 in the another body shaping one of both sides week that device holds mouth 232; This is respectively placed restrictions on portion 24 and places restrictions on to hold in the hole 23 towards this and protrude out, and makes this two place restrictions on and form one between the portion 24 and place restrictions on through hole 241, and this is placed restrictions on through hole 241 and has the through hole of placing restrictions on footpath D4; This places restrictions on the roller diameter D3 of through hole footpath D4 less than this roller 30; So make this roller 30 receive into this place restrictions on hold receive after the hole 23 this place restrictions on hold mouthfuls 231 and this place restrictions on through hole 241 restrictions, and this bearing ring body 20 connects by this outer ring surface 22 and faces this and respectively place restrictions on portion 24 and form a depressed part 25 respectively, present embodiment is that the device to this bearing ring body 20 holds mouthful 232 peripheries and carries out riveting; Make outer ring surface 22 pressurizeds of this bearing ring body 20 this depressed part 25 that is shaped, make simultaneously by the material of outer ring surface 22 depressions to form those and place restrictions on portion 24 to placing restrictions on to hold to protrude out in the hole 23.

More than can place restrictions on the structural relation of the bearer ring of roller for the utility model, can be known by the said structure relation, the portion that places restrictions on 24 of one just can produce the effect of placing restrictions on roller 30 on the bearing ring body 20 of the utility model; And this is placed restrictions on portion 24 and is still formed by these bearing ring body 20 deformation own, does not need other material or member to reach the purpose of placing restrictions on roller 30 fully, has not only reduced cost of material; After this roller 30 is assembled into this bearing ring body 20; When this bearer ring will cooperate other mechanisms to use again, just need not worry that fully roller 30 has the problem that comes off, the assembly that can be more convenient for using; Promote the efficient that assembling is produced, and create higher economic benefit.
