Abstract
The utility model relates to a design scheme for a cutting sleeve type needle bearing composed of an inner sleeve, an outer sleeve and a rolling needle bracket on which a rolling needle is inlaid. The utility model is characterized in that the inner and the outer sleeves are respectively formed by the assembly of two corresponding sleeve bodies, and the rolling needle bracket is formed by the assembly of three equal brackets. The utility model changes the traditional condition that crank shafts can only be supported by bearing liners, raises the transmission efficiency, also solves the defect that when one shaft is used for support at a plurality of positions, the maintenance can be carried out only by detaching the shafts one by one from outside to inside, and raises the efficiency.
Description
The utility model relates to a kind of needle bearing, relates in particular to the combined needle bearing of a kind of FERRULETYPE.
At present, the motion of bent axle is supported and can only be realized with bearing shell, and the friction of bearing shell and between centers belongs to sliding friction.Because friction factor is bigger, reduced efficiency of transmission on the one hand, on the one hand because temperature rise is too high, usually occur " axis tile ", so that cause the mill axle, loss such as change watt.And concerning one multidigit support, because the diameter of axle is the same, the bearing that needs must be installed one by one in proper order.When damage of bearings that one of them particularly mediates, all bearings that just need unloading one by one of ecto-entad to be in its outer end, this certainly will increase engineering time, causes unnecessary loss.
The purpose of this utility model is to provide a kind of FERRULETYPE needle bearing design proposal at the deficiency of above-mentioned prior art existence, makes the assembly unit of needle bearing realization to axle, and bent axle supports and the drawback of coaxial multidigit support existence in the hope of solving.
Task of the present utility model is finished by following design proposal.Be the FERRULETYPE needle bearing by interior cover, overcoat and needle roller and be configured to that be characterised in that cover and overcoat are assembled by two corresponding bodies respectively in it, the needle roller support is assembled by third-class support.
Design proposal can further be done following perfect: promptly in the cover and overcoat separately wherein be respectively equipped with locating stud on a body, the place is provided with oilhole at locating stud.
According to the FERRULETYPE needle bearing that this programme is made, compare with the bearing shell that supports bent axle, owing to adopted the needle bearing structure, friction factor greatly reduces, can not produce " axis tile " phenomenon, improve efficiency of transmission, and the occasion that supports multidigit, the closo bearing that it is more traditional, installation, convenient disassembly, installation or removal have successively improved efficient, shorten maintenance time, reduced expense.
In the accompanying drawing, Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an assembling schematic representation of the present utility model.
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
Embodiment: the FERRULETYPE needle bearing is made of interior overcoat, needle roller support and the needle roller that is embedded on the support.In cover assembled by two the card bodies (3,3 ') that adapt with the diameter of axle.Its splicing position preferably is triangular shape, and the point of contact that can keep needle roller rolling surface and splicing line like this guarantees to roll steadily for minimum.Be embedded with needle roller (4) the needle roller support (2,2 ', 2 ") are that sub-stents such as three constitute, so that assembly unit.Overcoat is also assembled by two cutting ferrule bodies (1,1 ').Its splicing position and interior cover are equally preferably triangular in shape.On a cutting ferrule body (3 ') of interior cover, be provided with a locating stud (6) that is connected with axle, on a cutting ferrule body (1 ') of overcoat, be provided with a locating stud that links to each other with bearing support (5), and two locating stud centers be provided with oilhole.
During assembling, utilize the elasticity of bearing inner sleeve, aim at positioning pin hole, interior cutting ferrule body is loaded on the axle, put in again half body that is tip of overcoat being placed in, the two packaged needle roller supports that prepare are filled in along inside and outside cover gap, put in again last piece needle roller support assembly being buckled in, piece together embedding with another piece wild card body and become overcoat integral body, thereby constitute the FERRULETYPE needle bearing.
Claims (2)
1. by interior cover, overcoat and needle roller and a FERRULETYPE needle bearing that is configured to thereof, it is characterized in that said interior cover and overcoat are assembled by two corresponding bodies respectively, the needle roller support is assembled by third-class support.
2. by the described FERRULETYPE needle bearing of claim 1, in it is characterized in that cover and overcoat separately wherein be respectively equipped with locating stud on a body, be provided with oilhole in the locating stud center.
