Abstract
The invention relates to a device, in particular to an angular contact ball bearing clearance detection device. The angular contact ball bearing clearance detection device is characterized in that: a bearing supporting seat is connected with a bearing supporting seat cover plate; a detected bearing is arranged on the bearing supporting seat; a bearing inner ring pressing shaft is sleeved with a second thrust ball bearing and a spring, and one end which passes through the bearing supporting seat cover plate is connected with the detected bearing; the spring is sleeved with a rotating force bolt; one end of the rotating force bolt is provided with a first thrust ball bearing and is connected with a butterfly-shaped nut; the bearing inner ring pressing shaft is provided with scales; and a circumferential positioning pin is connected with the bearing inner ring pressing shaft. By adopting the technical scheme, the angular contact ball bearing clearance detection device provided by the invention has the advantages that an adjustable load device can be added on a detected bearing inner ring in advance; the axial clearance of the bearing is conveniently detected; and the structure is simple and compact.
Description
Technical field
The present invention relates to a kind of device, particularly a kind of angular contact ball bearing clearance detector.
Background technology
At present, known simple detection device structure is made up of bearing block and inner ring compact heap.During detection, complete inner circle compact heap self gravitation is as preload, and this preload does not reach requirement, and it is unadjustable, cause the internal space ring and external space ring thickness difference of selection inaccurate, two bearings pretightning force is inadequate, finally directly affects the rotating accuracy of assembled shaft and the serviceable life of bearing.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of angular contact ball bearing clearance detector, can not only preload, and can according to the convenient size regulating preload of the bearing of different requirements, different model.
The technical solution adopted for the present invention to solve the technical problems is: on bearing support block, increase a set of adjustable preload device, by moving axially of spin bolt, carry out the active length of regulating spring, spring force acts directly on bearing inner race compression axis, thus reaches an adjustable preload.The present invention is by bearing support block, detected bearing, circumference register pin, bearing inner race compression axis, bearing support block cover plate, spring, spin bolt, wing nut, first thrust ball bearing and the second thrust ball bearing composition, it is characterized in that: bearing support block is connected with bearing support block cover plate, bearing support block there is detected bearing, bearing inner race compression axis puts the second thrust ball bearing and spring, and be connected with detected bearing through the one end after bearing support block cover plate, spring outwards puts spin bolt, there is the first thrust ball bearing one end of spin bolt is connected with wing nut, bearing inner race compression axis there is quarter, circumference register pin is connected with bearing inner race compression axis.
Due to adopt technique scheme, the advantage that the present invention has and good effect are: can on measured bearing inner ring pre-add adjustable load device, detect the end-play of bearing easily, simple and compact for structure.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Figure of description is structural representation of the present invention.
1. bearing support blocks in figure, 2. detected bearing, 3. circumferential register pin, 4. bearing inner race compression axis, 5. bearing support block cover plate, 6. spring, 7. spin bolt, 8. wing nut, 9. the first thrust ball bearing, 10. the second thrust ball bearing.
Embodiment
In Figure of description, bearing support block (1) is connected with bearing support block cover plate (5), bearing support block (1) there is detected bearing (2), bearing inner race compression axis (4) puts the second thrust ball bearing (10) and spring (6), and be connected with detected bearing (2) through the one end after bearing support block cover plate (5), spring (6) outside puts spin bolt (7), there is the first thrust ball bearing (9) one end of spin bolt (7) is connected with wing nut (8), (4) have scale to bearing inner race compression axis, circumference register pin (3) is connected with bearing inner race compression axis (4).
Principle of work of the present invention: bearing (2) will be detected and be placed in bearing support block (1) center, rotate wing nut (8), spin bolt (7) promotes bearing inner race compression axis (4) downwards and detected bearing (2) coordinates, continue to rotate spin bolt (7) holddown spring (6), preload is passed to detected bearing (2) inner ring by the second thrust ball bearing (10) and inner ring compression axis (4).The rotatable spin bolt (7) of size of preload changes the length of spring (6), can read by the scale on bearing inner race compression axis (4).Circumference register pin (3) limits the rotary freedom of bearing inner race compression axis (4).Moving axially so just by spin bolt (7), carry out the active length of regulating spring (6), spring force acts on detected bearing (2) inner ring by the second thrust ball bearing (10) bearing inner race compression axis (4), thus reach an adjustable preload, detect the end-play of bearing easily.During detection, the present invention is placed on flat board, detected bearing (2) is placed on the bearing support block (1) in the present invention, lever meter and dial framework are placed on flat board, and adjust the position of lever meter gauge head, mobile the present invention, measures the difference in height of Internal and external cycle end face with lever meter.
Claims (1)
1. an angular contact ball bearing clearance detector, by bearing support block, detected bearing, circumference register pin, bearing inner race compression axis, bearing support block cover plate, spring, spin bolt, wing nut, first thrust ball bearing and the second thrust ball bearing composition, it is characterized in that: bearing support block (1) is connected with bearing support block cover plate (5), bearing support block (1) there is detected bearing (2), bearing inner race compression axis (4) puts the second thrust ball bearing (10) and spring (6), and be connected with detected bearing (2) through the one end after bearing support block cover plate (5), spring (6) outside puts spin bolt (7), there is the first thrust ball bearing (9) one end of spin bolt (7) is connected with wing nut (8), (4) have scale to bearing inner race compression axis, circumference register pin (3) is connected with bearing inner race compression axis (4).
