Description
Technical field
The present invention relates to bearing detecting device, be 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 bearing assemble 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 by 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.As seen, cone spacer height dimension between two bearing inner race narrow end surfaces has determined the end-play of whole device, and then determines the starting torque size.
In conjunction with Fig. 2, generally, after required end-play is given, obtain the spacer ring height dimension by following computing method, that is: first rotate respectively each row roller and lasso before the measurement, after part all is in the normal position, press certain load G, and guarantee rolling body and raceway uniform contact, measure the bearing outer ring narrow end surface to the distance h 1 between the inner ring narrow end surface (position I), repeat above method and measure h2 (position II); As calculated, B-B=h1+h2-C; B-B is required spacer ring height dimension.As seen, prior art realizes end-play by the grinding-in spacer ring.
And in practice, when the height dimension of spacer ring B-B is given, need to realize end-play by the apolegamy spacer ring, above match grinding method is obviously not all right.And need fill 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), two inner rings heating assemblings, with the axle interference fit
3), set nut uses torque spanner to be worth on request pinning
4), on housing, the spacer ring between two outer ring wide end surfaces melts mutually with housing
Above installation is due to the amount that exists interference, and cold and hot installation radial dimension changes greatly, and the deviation between each coordinates is inconsistent, causes starting torque to be difficult to reach between 50N.M-60N.M, and this problem is perplexing manufacturer always.
Summary of the invention
In order to solve the problem in background technology, technical matters to be solved by this invention is to disclose a kind of Self-loaded measuring table; This test desk can by the result of one-shot measurement, be matched qualified spacer ring and satisfy installation requirement.
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 by the following technical solutions:
A kind of Self-loaded measuring table comprises instrument, surveys ring and load, and described load is made of upper cover and outer ring, the weight of upper cover and outer ring and be that the check taper roll bearing of national Specification assembles load required when high; Upper cover middle part has the hole, and the instrument gauge rod passes upper cover by this hole, and instrument is positioned at by the holding screw that is arranged on middle part, upper cover upper surface boss and covers; Middle part, upper cover 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 projection, sheathed spring on boss, the projection diameter size of described sheathed spring is corresponding to the groove size at middle part, upper cover lower surface; Described outer ring inwall is provided with raised step near the place, lower surface.
For better implementing the invention, middle part, described survey ring lower surface is provided with groove, makes survey encircle the lower surface and forms the thin-walled ring.
For better implementing the invention, described survey ring maximum outside diameter place and outer ring inwall are clearance fit.
For better implementing the invention, described upper cover screws by external thread and outer ring internal thread.
Instrument is to after zero, by inwall raised step lower surface, outer ring is put on the wide end surface of taper roll bearing outer ring stably, slightly rotate the wide end surface of step lower surface and bearing outer ring is fully fitted, then surveying ring can be under the effect of spring, the narrow end surface of being close to bearing inner race, read again the upper pointer of table, 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.

Embodiment
In conjunction with Fig. 3, the Self-loaded measuring table of the present embodiment comprises instrument 6, surveys ring 2 and load, and wherein, load is made of upper cover 3 and outer ring 1, and upper cover 3 screws by external thread and outer ring 1 internal thread; The weight of upper cover and outer ring and be the check taper roll bearing assembling of national Specification required load when high; Upper cover 3 middle parts have the hole, and instrument 6 gauge rods pass upper cover 3 by this hole, and instrument 6 is positioned on upper cover 3 by the holding screw 5 that is arranged on protruding 7 positions, middle part, upper cover upper surface; Middle part, upper cover lower surface is provided with groove 9; Be provided with in 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 projection 10, sheathed spring 4 on protruding 10 positions, the projection diameter size of described sheathed spring is corresponding to groove 9 sizes at middle part, upper cover lower surface; The outer ring inwall is provided with raised step 11 near the place, lower surface.
Wherein, survey ring 2 middle parts, 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 to carry out under certain load.Due to the weight of upper cover and outer ring be the check taper roll bearing assembling of national Specification required load when high, namely satisfy this condition.Now loaded measuring table is placed on zero platform 14, the less dial plate of instrument is transferred to required basic size h, this moment, large 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, slightly rotate both are fully fitted, then surveying ring can be under the effect of spring, its lower surface thin-walled is close to the narrow end surface of inner ring, read again the upper pointer of table, just can draw the bearing outer ring wide end surface to the actual deviation h value between the inner ring narrow end surface.
Through once reaching qualification rate higher to many to joining the spacer ring practice, manpower and materials have been economized to manufacturer.
In literary composition, the indication bearing is single-row tapered roller bearing.
