Description
Technical field
The present invention relates to bearing performance detection technique field, relate in particular to a kind of assembly angular contact ball bearing end-play measurement mechanism.
Background technology
Just there is end-play single-row angular contact ball bearing in itself, and the angular contact ball bearing end-play after the assembly has just more strengthened.Combine suitable play angular contact ball bearing and be usually used on the machine tool chief axis, improve main axis stiffness and running accuracy.So play needed strictness to adjust when the pairing angular contact ball bearing dispatched from the factory.
That the assembly angular contact ball bearing has is back-to-back, face-to-face, three kinds of basic matching forms of series connection, and matched bearing is in the two bearings protrusion amount of assembly face end with for δ 1+ δ 2 is an end-play, as shown in Figure 1.
The assembly angular contact ball bearing that precision machine tool is used requires very strict to end-play, but existing measurement mechanism complex structure and measuring accuracy are low.Therefore, need a kind of accurately easy end-play measurement mechanism of development.
Summary of the invention
In order to overcome the existing in prior technology defective, the purpose of this invention is to provide a kind of assembly angular contact ball bearing end-play measurement mechanism, it is simple in structure, and is easy to operate, the measuring accuracy height.
To achieve these goals, technical scheme of the present invention is as follows:
Assembly angular contact ball bearing end-play measurement mechanism, comprise load piece, centering sleeve, cone spacer, outer ring spacer, packing ring and surveying instrument, the centering sleeve is placed on the platform of surveying instrument, gasket sleeve is on the centering sleeve, measured bearing is enclosed within on the centering sleeve, and the following of the inner ring of measured bearing supported by packing ring, and the load piece is placed on the measured bearing, cone spacer connects the inner ring of two measured bearings, and outer ring spacer connects the outer ring of two measured bearings.
Above-mentioned outer ring spacer is the annular ring that is made of separable pair of semi-ring.
The invention has the beneficial effects as follows:
1, outer ring spacer is made two semi-ring types of separate type, and is easy to operate, is applicable to the bearing processing factory of various scales;
2, can guarantee measuring accuracy, the flatness of each parts end face, parallel error all require to be 0.0005mm, can guarantee the accuracy of form and position, the not centering of load piece, and the upper and lower end face easily processes;
3, adopt the centering sleeve, can guarantee bearing and the centering of each annex;
4, simple in structure, cost is low.

Among the figure: 1, load piece, 2, the centering sleeve, 3, cone spacer, 4, outer ring spacer, 5, packing ring, 6, measured bearing, 7, surveying instrument.
Embodiment
Below in conjunction with accompanying drawing the present invention is described in further details.
As shown in Figure 2, assembly angular contact ball bearing end-play measurement mechanism of the present invention comprises: load piece 1, centering sleeve 2, cone spacer 3, outer ring spacer 4, packing ring 5 and surveying instrument 7; Two measured bearings 6 are placed up and down and are constituted the pairing bearing.Centering sleeve 2 is placed on the platform of surveying instrument 7, packing ring 5 is enclosed within on the centering sleeve 2, measured bearing 6 is enclosed within on the centering sleeve 2, the following of the inner ring of measured bearing 6 supported by packing ring 5, load piece 1 is placed on the measured bearing 6, cone spacer 3 connects the inner ring of two measured bearings 6, and outer ring spacer 4 connects the outer ring of two measured bearings 6.
Each component function of assembly angular contact ball bearing end-play measurement mechanism of the present invention is as follows:
Suffered axial force when load piece 1 is the work of simulation measured bearing 6 and a kind of load of doing, its effect are exactly to give to match the bearing loading moment;
Centering sleeve 2 is used for fixing the tram of Internal and external cycle when measuring of measured bearing 6, and dislocation or landing take place each parts when preventing to measure;
Outer ring spacer 4 is used to connect two outer rings of matching bearing, makes it to form the transmission of power, for two semi-ring types, makes separate type, so that take away outer ring spacer 4 and do not move top measured bearing 6;
Surveying instrument 7 is used to show the instrument of pairing bearing end-play.
Embodiment:
Surveying instrument 7 adopts G905 height-gauge devices, according to the different matching methods of bearing, on G905 height-gauge device, measured bearing 6 is added that annexes such as measuring load measures.It is as follows that present embodiment is with the bearing end-play measuring process of back-to-back DB group mode that example describes:
At first, according to the specifications design special measurement load and the annex of measured bearing 6, wherein outer ring spacer is two semi-ring types, and outer ring spacer is higher than cone spacer, and its value is a=0.15～0.3mm; Secondly, according to shown in Figure 2 measured bearing and measurement annex are placed on the G905 instrument, with zero adjusting; At last, outer ring spacer 4 is taken away, as shown in Figure 3, write down the reading of instrument this moment, deduct the difference in height a value of cone spacer than outer ring spacer with this reading, institute's value is exactly the end-play value of pairing bearing.
Assembly angular contact ball bearing end-play measurement mechanism of the present invention can satisfy the requirement of terminal client to the matched bearing end-play, and can provide the detection data for the user; Can be applied to need to measure the users such as bearing manufacturing plant of assembly angular contact ball bearing end-play.
