Abstract
The utility model relates to a conical roller bearing pre-tightening and gap adjusting device. The conical roller bearing pre-tightening and gap adjusting device resolves the problems that a conical roller beating is not convenient to adjust and operate at present. The conical roller bearing pre-tightening and gap adjusting device comprises a pull rod, a positioning plate, a tool body, a limiting nut, and a spring-loaded thrust meter, wherein the center of the tool body is provided with a circular through hole, the head portion in a circular truncated cone shape, of the positioning plate is placed inside the through hole of the tool body and is tightly fixed with the tool body, and the other side of the positioning plate is a shaft portion which is used for installing a bearing, a bearing space ring, and a bearing seat. Besides, the pull rod is arranged inside a cavity of the positioning plate, one end of the pull rod is an unthreaded shaft, the other end of the pull rod is a threaded shaft, one end of the unthreaded shaft is provided with a disc-shaped head portion used for compressing a bearing end face, the threaded shaft is provided with the limiting nut, and the spring-loaded thrust meter is connected with the end portion of the threaded shaft of the pull rod. The conical roller bearing pre-tightening and gap adjusting device is convenient and simple to operate, high in efficiency, low in manufacture cost, capable of conveniently conducting conical roller bearing pre-tightening and gap adjustment.
Description
Technical field:
The utility model relates to a kind of taper roll bearing pretension and lash adjusting device.
Background technology:
The general paired use of taper roll bearing, the adjustment in gap is extremely important, excesssive gap or the too small life-span that all can have a strong impact on bearing.Method of adjustment and the detection means in general gap have two kinds: 1, trail and error procedure.Namely adopt and adjust pad, the pad of milled series is selected during for assembling in advance; 2, match grinding method.Namely pass through repeatedly match grinding bearing spacer.It all is to force to add an axial force (power value or moment), front and back to adopt dial gauge or the amesdial measurement realization of beating that these two kinds of methods detect.When taper roll bearing being carried out the gap adjustment, though trail and error procedure is more easy to operate, need in the system that whole product component forms, carry out operation inconvenience at present; And with the match grinding method taper roll bearing is carried out the gap when adjusting, need to adjust with the parts of product, bearing pre-tightened is difficult the realization, bearing is hot-pressed onto on the gear shaft simultaneously, need repeatedly dismounting bearing from the gear shaft when wanting the match grinding bearing spacer, the adjustment process complexity is lengthy and tedious, wastes time and energy, and regulated efficiency is low, cost is high.
Summary of the invention:
The utility model has solved the problem of present taper roll bearing adjusting operation inconvenience by a kind of device that can conveniently carry out pretension and gap adjustment to taper roll bearing is provided.
The utility model is realized by following technical scheme:
A kind of taper roll bearing pretension and lash adjusting device, comprise pull bar, positioning disk, body of tool, stop nut and weight beam, the body of tool center is provided with a manhole, the round table-like head of positioning disk is installed in the circular hole of body of tool and is fastening with body of tool, the opposite side of positioning disk is for being used for installing bearing, the axial region of bearing spacer and bearing block, be provided with pull bar in the positioning disk inner chamber, pull bar one end is optical axis, the other end is thread spindle, optical axis one end band is useful on the discoid head of compression axis socket end face, with stop nut, weight beam is connected with the end of pull rod screw axle on the thread spindle.
The utility model is easy and simple to handle, efficient is high, low cost of manufacture, can conveniently carry out pretension and gap adjustment to taper roll bearing.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment:
Below in conjunction with accompanying drawing this utility model is further described:
As shown in Figure 1, a kind of taper roll bearing pretension and lash adjusting device, by pull bar 1, positioning disk 2, body of tool 3, stop nut 4, screw 5 and weight beam 6 form, described body of tool 3 centers are provided with a manhole, the round table-like head of positioning disk 2 is installed in the circular hole of body of tool 3 and is fastening with body of tool 3 usefulness screws 5, positioning disk 2 opposite side axial regions are installed bearing 7, bearing spacer 8, bearing block 9, be provided with pull bar 1 in positioning disk 2 inner chambers, pull bar 1 one ends are optical axis, the other end is thread spindle, optical axis one end band is useful on the discoid head that compression axis holds 7 end faces, with stop nut 4, weight beam 6 is connected with the hole of pull bar 1 thread spindle one end on the thread spindle.Owing to adopt weight beam 6 reinforcings, they can Measurement accuracy bearing 7 pretightning forces, at pull bar stop screw 4 are set simultaneously, and it can guarantee that the bearing clearance measuring process conveniently carries out, and measurement data accurately and reliably.
When pretension and gap are adjusted, at first bearing 7, bearing spacer 8, bearing block 9 all are contained in the axial region of positioning disk 2 opposite sides on pretension and the lash adjusting device, weight beam 6 is applied to desired pretightning force on bearing 7 inner rings by pull bar 1 discoid head, then spacing by stop nut 4, measure beating of bearing block 9 end faces with dial gauge or amesdial 10 again, calculate the difference with actual requirement end play, bearing spacer 8 can be pulled down match grinding according to measured value, adjust rear do pairing mark and get final product in order to follow-up assembling use.For the bearing 7 of different size, the positioning disk 2 in replaceable taper roll bearing pretension and the lash adjusting device is realized pretension and gap adjustment.
