Description
Technical field
The utility model relates to bearing detecting device, is specifically related to a kind of load detection device that carries that is applied to single-row tapered roller bearing.
Background technology
As shown in Figure 1, when the bearing assembling was used, the two cover single-row tapered roller bearings of arranging in pairs back-to-back were to adjust end-play to realize needed starting torque through being configured in two spacer rings between the bearing inner race narrow end surface.This configuration is preset supporting collocation form, i.e. supporting has limited the axial displacement of axial both direction, and another supporting, after given prefastening torque (required end-play) lock nut, revolving shell will reach the starting torque of regulation.It is thus clear that cone spacer height dimension between two bearing inner race narrow end surfaces has determined the end-play of whole device, and then determine the starting torque size.
In conjunction with Fig. 2, generally, after required end-play is given; Obtain the spacer ring height dimension through following computing method, that is: rotate each row roller and lasso respectively earlier before measuring, after part all is in the normal position; Press certain load G; And guarantee rolling body and raceway uniform contact, measurement axis bearing outer-ring narrow end surface repeats above method measuring h 2 (position II) to the distance h 1 between the inner ring narrow end surface (position I); Through calculating B-B=h1+h2-C; B-B is required spacer ring height dimension.It is thus clear that prior art realizes end-play through the grinding-in spacer ring.
And in the practice, when the height dimension of spacer ring B-B is given, need to realize end-play through the apolegamy spacer ring, above match grinding method is obviously not all right.And need adorn support in the erecting stage, join spacer ring, realize starting torque, there is following requirement at the configuration scene simultaneously:
1), two outer ring room temperature cold settings, with the housing interference fit
2), the heating assembling of two inner rings, with the axle interference fit
3), set nut uses torque spanner to be worth pinning on request
4), the spacer ring between two outer ring wide end surfaces melts with housing mutually on the housing
More than install owing to exist the amount of interference, cold and hot installation radial dimension changes greatly, and the deviation between each cooperates is inconsistent, causes starting torque to be difficult to reach between the 50N.M-60N.M, and this problem is perplexing manufacturer always.
Summary of the invention
In order to solve the problem in the background technology, the utility model technical matters to be solved is to disclose a kind of load measurement platform that carries; This test desk can be matched qualified spacer ring and satisfy installation requirement through the result of one-shot measurement.
When measuring, at first to solve be exactly the bearing outer ring wide end surface to the size accuracy between the inner ring narrow end surface, in conjunction with the characteristics of single-row tapered roller bearing, invented this test desk from on-load, specifically adopt following technical scheme:
A kind of load measurement platform that carries comprises instrument, surveys ring and load, and said load is made up of loam cake and outer ring, the weight of loam cake and outer ring and assemble load required when high for the check taper roll bearing of national Specification; Loam cake middle part has the hole, and the instrument gauge rod passes loam cake through this hole, and instrument is positioned at through the holding screw that is arranged on middle part, loam cake upper surface boss and covers; Middle part, loam cake lower surface is provided with groove; Be provided with in the outer ring and survey ring, survey middle part, ring upper surface and be provided with convexity, sheathed spring on the boss, the projection diameter size of said sheathed spring is corresponding to the groove size at middle part, loam cake lower surface; Said outer ring inwall is provided with raised step near the place, lower surface.
Be better implement the invention, middle part, said survey ring lower surface is provided with groove, makes to survey ring lower surface formation thin-walled ring.
Be better implement the invention, said survey ring maximum outside diameter place and outer ring inwall are clearance fit.
Be better implement the invention, said loam cake screws through external thread and outer ring internal thread.
Instrument is to after zero; Through inwall raised step lower surface, outer ring is put on the wide end surface of taper roll bearing outer ring stably; Rotating slightly fully fits the wide end surface of step lower surface and bearing outer ring, then surveys ring and can under the effect of spring, be close to the narrow end surface of bearing inner race; Read table again and go up pointer, just for the outer ring wide end surface to the actual deviation h value between the inner ring narrow end surface.Measure simply, easy to use, the accuracy of apolegamy spacer ring is high.
Description of drawings
Fig. 1 is the existing single-row tapered roller bearing assembly structure synoptic diagram of arranging in pairs back-to-back;
Fig. 2 is the structural representation of existing grinding-in spacer ring method;
Fig. 3 is the structural representation that load measurement platform instrument is matched single-row tapered roller bearing spacer ring height zero back that carries of the invention;
Among the figure: 1, outer ring; 2, survey ring; 3, loam cake; 4, spring; 5, holding screw; 6, instrument; 7, convexity; 8, gauge rod; 9, groove; 10, convexity; 11, raised step; 12, groove; 13, single-row tapered roller bearing; 14, to zero platform.
Embodiment
In conjunction with Fig. 3, present embodiment carry the load measurement platform, comprise instrument 6, survey ring 2 and load, wherein, load is made up of loam cake 3 and outer ring 1, loam cake 3 screws through external thread and outer ring 1 internal thread; The weight of loam cake and outer ring and assemble load required when high for the check taper roll bearing of national Specification; Loam cake 3 middle parts have the hole, and instrument 6 gauge rods pass loam cake 3 through this hole, and instrument 6 is positioned on the loam cake 3 through the holding screw 5 that is arranged on protruding 7 positions, middle part, loam cake upper surface; Middle part, loam cake lower surface is provided with groove 9; Be provided with in the outer ring 1 and survey ring 2, surveying ring maximum outside diameter place and outer ring inwall is clearance fit; Survey middle part, ring upper surface and be provided with convexity 10, sheathed spring 4 on protruding 10 positions, the projection diameter size of said sheathed spring is corresponding to groove 9 sizes at middle part, loam cake lower surface; The outer ring inwall is provided with raised step 11 near the place, lower surface.
Wherein, survey middle part, ring 2 lower surfaces and be provided with groove 12, make and survey the ring lower surface and form the thin-walled ring, so that better control accuracy when measuring.
During use, follow national standard, detecting taper roll bearing assembling height is under certain load, to carry out.Because the weight of loam cake and outer ring and for the check taper roll bearing of national Specification assembles load required when high promptly satisfies this condition.The load measurement platform is placed on zero platform 14 at present, the littler dial plate of instrument is transferred to required basic size h, this moment, big dial plate pointer was to zero.After good, whole device is put on the wide end surface of bearing outer ring stably; The wide end surface that is inwall raised step lower surface, outer ring and taper roll bearing outer ring is fitted; Rotating slightly fully fits both, and then surveying ring can be under the effect of spring, and its lower surface thin-walled is close to the narrow end surface of inner ring; Read table again and go up pointer, just can draw the bearing outer ring wide end surface to the actual deviation h value between the inner ring narrow end surface.
Through putting into practice joining spacer ring many, it is higher once to reach qualification rate, has economized manpower and materials to manufacturer.
The indication bearing is single-row tapered roller bearing in the literary composition.
