Abstract
The utility model relates to an eccentricity adjustable type eccentric bearing whose bearing body comprises an inner ring body, a middle ring body and an outer ring body. The inner ring body is arranged in the middle ring body which is arranged in the outer ring body. A rolling body is arranged between the inner ring body or the outer ring body and the middle ring body. The outer ring body or the inner ring body and the middle ring body are fixed by using splines. The axle centers of the outer column face of the middle ring body and the inner column face of the outer ring body or the axle centers of the outer column face of the inner ring body and the inner column face of the middle ring body are eccentric with the central axle of the inner ring body. The utility model has the advantages of simple structure, compact design, low cost and easy adjustment of eccentric quantity, and realizes fine adjustment of the eccentric quantity.
Description
The utility model relates to the capacity eccentric bearing technical field, is the adjustable capacity eccentric bearing of a kind of offset.
Existing capacity eccentric bearing just utilizes the off-centre (as installing eccentric bushing etc.) of two component location guide cylinders between the bearing enclose body usually, realize eccentric requirement, offset can not change, unless change the different bearing of offset, dismantles and install all time-consuming taking a lot of work like this.
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and the adjustable capacity eccentric bearing of offset that designs a kind of easy adjustment offset.
The purpose of this utility model realizes by following measure: the bearing support of the adjustable capacity eccentric bearing of this offset comprises inner ring body, middle circle body and outer ring body, inner ring body is installed in the middle circle body, and middle circle body is installed in the outer ring body, between inner ring body or outer ring body and the middle circle body rolling element is housed, between outer ring body or inner ring body and middle circle body, adopt to spend to be good for and fix the axle center of the axle center of external cylinder of centre circle and outer ring body inner cylinder or inner ring body outer cylinder and middle circle body inner cylinder and inner ring body eccentricity of central axis; Between inner ring body and the middle circle body rolling element is housed, adopts between outer ring body and the middle circle body to spend to be good for and fix the axle center of external cylinder of centre circle and outer ring body inner cylinder and inner ring body eccentricity of central axis; Between outer ring body and the middle circle body rolling element is housed, adopts between inner ring body and the middle circle body to spend to be good for and fix the axle center of inner ring body outer cylinder and middle circle body inner cylinder and inner ring body eccentricity of central axis; Rolling element is columniform or spherical or truncated cone; Hua Jian is leg-of-mutton or involute profile or cycloidal tooth profile; Be carved with the offset scale on eccentric inner ring body or middle circle body or the outer ring body.
Accompanying drawing 1 is the side view cutaway drawing of accompanying drawing 2, and accompanying drawing 2 is the utility model embodiment 1 a plan view;
Accompanying drawing 3 is the side view cutaway drawing of accompanying drawing 4, and accompanying drawing 4 is the utility model embodiment 2 a plan view;
Accompanying drawing 6 is the side view cutaway drawing of accompanying drawing 5, and accompanying drawing 6 is the utility model embodiment 3 a plan view;
Coding is respectively in the accompanying drawing: 1 is outer ring body, and 2 is middle circle body, and 3 is inner ring body, and 4 is strong for spending, and 5 is rolling element, and 6 is bearing support.
Below in conjunction with embodiment and accompanying drawing the utility model is further described:
Shown in attached Fig. 1 and 2, this embodiment's 1 bearing support 6 comprises inner ring body 3, middle circle body 3 and outer ring body 1, and inner ring body 3 is installed in the middle circle body 3, and middle circle body 2 is installed in the outer ring body 1, between inner ring body 3 and the middle circle body 3 rolling element 5 is housed, and rolling element 5 employings are columniform; Between outer ring body 1 and middle circle body 2, adopt spend strong 4 fixing, spend strong 4 can adopt leg-of-mutton or involute profile or cycloidal tooth profile, the axle center of middle circle body 2 outer cylinders and outer ring body 1 inner cylinder and inner ring body 3 eccentricity of central axis.
Shown in accompanying drawing 3 and 4, this embodiment 2 is with embodiment 1 difference: rolling element 5 is spherical.
Shown in accompanying drawing 5 and 6, this embodiment 3 and embodiment's 1 difference is: between outer ring body 1 and the middle circle body 2 rolling element 5 is housed, and rolling element 5 can be columniform or spherical or truncated cone, be preferably spherical, adopt between inner ring body 3 and the middle circle body 2 and spend strong 4 to fix the axle center of inner ring body 3 outer cylinders and middle circle body 3 inner cylinder and inner ring body 3 eccentricity of central axis.
Shown in accompanying drawing 1,2,3,4,5 and 6, have keyway in the inboard, thick round position of inner ring body 3 or the outside, thick round position of outer ring body 1, the inner ring body 3 of the adjustable capacity eccentric bearing of this offset or outer ring body 1 are installed firmly.
For the ease of regulating offset, on the inner ring body 3 of off-centre or middle circle body 3 or outer ring body 1, be carved with the offset scale, so also be convenient to accurate display eccentric amount.
When needs are adjusted offset, at first will spend strong 4 to throw off, and just can adjust offset then, and can realize the small adjustment of offset, for embodiment 1 and 2, adjust the assembling orientation between outer ring body 1 and the middle circle body 2, just can realize the adjustment of offset, and for embodiment 3, adjust the assembling orientation between inner ring body 3 and the middle circle body 3, can realize the adjustment of offset equally, will spend strong 4 to install at last again after, just can use the adjustable capacity eccentric bearing of this offset.
The utility model is simple in structure, and is compact to design, and cost is low, and offset is easy to adjust, and can realize the small adjustment of offset.
