The inner gear ring tapered roller bearing with the above structure can effectively provide axial loading force and radial loading force and meet more using requirements.
Description
Technical field
The utility model relates to mechanical parts field, relates in particular to a kind of external toothing tapered roller bearing.
Background technique
Bearing is as basic mechanical parts, every kind of bearing has different functions in use, for example axial load resistant, anti-radial load or anti-axial-radial connected load, or sliding friction is changed into rolling friction, people need to select size and the type of bearing according to different working environments.The most frequently used bearing has tapered roller bearing, roller bearing and this three class of ball series bearing, wherein roller bearing can only bear radial load, ball series bearing mainly bears radial load, only bear a part of thrust load, but in actual use, axial load ability and radial load ability to bearing have various requirements as required, are generally to adopt roller bearing and ball series bearing to be used in conjunction with to reach usage requirement.But the increase of number of bearings inevitably causes cost to increase, and two kinds of different bearings are used in combination the complexity that can increase mechanism, improve rate of fault, and mechanism is declined working life.
Model utility content
In order to address the above problem, the utility model provides a kind of external toothing tapered roller bearing, and it can effectively provide axial load power and radial load power, and sound construction, not fragile.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of external toothing tapered roller bearing, comprise outer ring, it also comprises two inner rings, spacer ring, two row tapered rollers, between described two inner rings, be provided with spacer ring, between described two inner rings and outer ring, form conical raceway, described two row tapered rollers are arranged in described conical raceway by retainer, between described two row tapered rollers and the axial direction of outer ring, there is angle, the less end face of external diameter of described two row tapered rollers is oppositely arranged, the axial height of described outer ring is less than the axial height sum of described two inner rings, and the outer radial of described outer ring is provided with tooth.
Described two row tapered rollers are with respect to the radial symmetric setting of outer ring.
The tooth in outside, described outer ring is straight-tooth.
Described retainer comprises support body, is radially provided with mounting hole on described support body along outer ring, and described tapered roller is placed in mounting hole.
Described support body comprises the assembly department and the kink that interlink, and described mounting hole is located at assembly department, and kink contacts described spacer ring outside.
Described assembly department and kink are formed in one.
The joint of described assembly department and kink is arc.
Described mounting hole is corresponding with tapered roller quantity.
Owing to thering is said structure, the utlity model has following advantage:
1, the utility model external toothing tapered roller bearing, two row tapered rollers can regulate, thereby axial load power and radial load power are provided effectively, meet actual demand.
2, the utility model external toothing tapered roller bearing, retainer is formed in one, firm in structure, not fragile.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model external toothing tapered roller bearing.
Fig. 2 is the structural representation of retainer.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail, to understand better the utility model:
As shown in Figure 1, the external toothing tapered roller bearing that the utility model provides, comprises outer ring 1, it also comprises two inner rings 2, spacer ring 3, two row tapered rollers 4, the outer radial of described outer ring 1 is provided with tooth 5, is provided with 3, two inner rings 2 of spacer ring and is fixed on spacer ring 3 by screw between described two inner rings 2; Every row tapered roller 4 is along the circumferential direction around inner ring 2, and every row tapered roller 4 has 3 at least, is preferably 31, and 31 tapered rollers make this bearing have larger anti-load carrying capacity, adapts to use on heavy slow-speed of revolution equipment.Outer ring 1 and be fixed between two inner rings 2 of spacer ring 3 and form conical raceway, the internal diameter of described conical raceway matches with the external diameter of tapered roller, is preferably the external diameter that is slightly larger than tapered roller, is difficult for again loosening being as the criterion can ensure that tapered roller rotates.The axial height of described outer ring 1 is less than the axial height sum of described two inner rings 2, and two row tapered rollers 4 are arranged between described two inner rings 2 and outer ring 1 by retainer 6.Between described two row tapered rollers 4 and the axial direction of outer ring 1, there is angle, angle between tapered roller 4 described in every row and described outer ring 1 are axial is greater than 0 ° and is less than 90 °, regulate the axial anti-load carrying capacity of bearing and the radially distribution of anti-load carrying capacity by the variation of angle, to make bearing can reach best performance in Environmental Conditions, so just can significantly extend the working life of bearing.The less end face of external diameter of described two row tapered rollers 4 is oppositely arranged, and described two row tapered rollers 4 are with respect to the radial symmetric setting of outer ring 1.Two row tapered rollers 4 relatively and be symmetrical arranged and can not only strengthen the load that the load-carrying ability of bearing can also make bearing bear simultaneously and be distributed on whole bearing, avoid because localised load is crossed the situation generation that causes by force whole bearing to be scrapped, further improve the working life of bearing, can be by regulating the thickness of cone spacer 2 to adjust the axial distance of play and two row rollers 4.
The tooth 5 in 1 outside, described outer ring can better adapt to the needs in the actual use of bearing, is straight-tooth in the present embodiment, certainly other profile of tooth such as helical teeth all can, set according to the actual requirements.
As shown in Figure 2, this retainer 6 comprises support body 7, and described support body 7 comprises the assembly department 8 and kink 9 that interlink, and described assembly department 8 is radially provided with mounting hole 10 along outer ring 1, kink 9 contacts described spacer ring 3 outsides, and described tapered roller 4 is placed in mounting hole 10.When the tooth 5 of the outer ring 1 of this bearing is subject to rubbing, can produce a large amount of load, the retainer of this structure, because the more therefore sound construction of support body entity part is not easy to damage because of large load, improves bearing working life.
In order further to increase the fastness of retainer, can, by one-body molded with kink 9 described assembly department 8, be processed by a monoblock sheet material.
Can also be set to arc with the joint of kink 9 by described assembly department 8, to reduce the difficulty of processing of sheet material.
Above-described embodiment is only for the utility model creation example is clearly described, and not the utility model is created the restriction of embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also giving exhaustive to all mode of executions.All any apparent variations of being extended out within spirit of the present utility model and principle or variation are still among the utility model is created the protection domain of claim.
