A main reducer pad selecting device comprises a pressure head, a measurement sensor, a measurement platform and a pedestal. The measurement platform is fixedly installed at the axle center of the pedestal. A supporting surface of the pedestal is cooperated with an outer end face of a bearing. The measurement sensor is fixedly installed on the pressure head. A supporting surface of the pressure head is cooperated with an outer end face of a bearing. The main reducer pad selecting device utilizes twice downward pressing to indirectly measure a gap distance between a front bearing of an axle drive bevel pinion and a rear bearing of the axle drive bevel pinion, and then selects a required pad according to the gap distance. The main reducer pad selecting device is high in measurement precision, reliable in data, and good in repeatability, and reduces labor intensity of operating workers and improves efficiency of main reducer assembly.
Description
Technical field
The utility model relates to car deceleration device field, relates in particular to a kind of speed reduction unit assembly tooling.
Background technology
Main reducing gear is the critical piece that reduces rotating speed in automotive transmission, increases moment of torsion.Concerning the vertical automobile of putting of engine, as shown in Figure 1, in the rotating shaft 11 of drive bevel gear 4, be provided with two bearings, two bearings are respectively drive bevel gear front bearing 1 and drive bevel gear rear bearing 3, the outer driven wheel of differential 5 engaging with it that is provided with of drive bevel gear 4, between the inner ring of drive bevel gear front bearing 1 and drive bevel gear rear bearing 3, be provided with cushion block 2, main reducing gear utilizes master/slave dynamic bevel gear transmission to change power direction.After transmission speed being lowered by main reducing gear, can obtain higher output torque, thereby obtain larger driving force.
The assembly quality of automobile main reducer, has influence on the performance of speed reduction unit, and two relative taper roll bearings fill to such an extent that too tightly make the pretightning force of main reducing gear too large, reduces the transmission efficiency of main reducing gear, causes bearing heating, affects bearing life and even kills; If two bearing dress get Tai Song, pretightning force is inadequate, causes assembly Stiffness and main shaft axial float.So the selection of cushion block 2 thickness between two bearings just seems particularly important.
At present because drive bevel gear front bearing 1 cannot directly measure with the gap between the inner ring end face of drive bevel gear rear bearing 3, so mainly realize by trial assembly repeatedly in the time of selection cushion block 2.Trial assembly method is repeatedly to allow experienced assembler by virtue of experience choose pad thickness, installs the minimum moment that rear measurement allows main shaft rotate, and obviously, trial assembly method is repeatedly taxed one's mind and strength, inefficiency.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of main reducing gear pad selecting arrangement, this device utilizes the clearance distance pressing down for twice between indirect measurement drive bevel gear front bearing and drive bevel gear rear bearing, can choose needed cushion block according to this distance again, measuring accuracy is high, data are reliable, reproducible, not only alleviate operator's labour intensity but also improved the efficiency of main reducing gear assembling.
The utility model is achieved in that a kind of main reducing gear pad selecting arrangement, comprise pressure head, survey sensor, measuring table and base, described measuring table is fixedly mounted on the axle center of base, the supporting surface of base matches with the outer face of bearing, described survey sensor is fixedly mounted on pressure head, and the supporting surface of pressure head matches with the outer face of bearing.
Described pressure head is rotary press head.
Described survey sensor is displacement transducer.
The utility model main reducing gear pad selecting arrangement utilizes the clearance distance pressing down for twice between indirect measurement drive bevel gear front bearing and drive bevel gear rear bearing, can choose needed cushion block according to this distance again, measuring accuracy is high, data are reliable, reproducible, not only alleviate operator's labour intensity but also improved the efficiency of main reducing gear assembling.

Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that ability technician can make various changes or modifications the utility model after having read the content of the utility model statement, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
As shown in Figure 2,3, 4, a kind of main reducing gear pad selecting arrangement, comprise pressure head 6 and be fixedly mounted on the survey sensor 7 on pressure head 6, pressure head 6 is responsible for survey sensor 7 to press to measuring table 8, in the time that survey sensor 7 contacts with measuring table 8, can send signal, now pressure head 6 stops depressing; Stability while driving survey sensor 7 displacement in order to improve pressure head 6, improve measuring accuracy, in the present embodiment, described pressure head 6 adopts rotary press head, survey sensor 7 is a displacement transducer, and pressure head 6 is pressed on bearing and with bearing inner race slow circumvolve, utilizes the rotation of screw thread to make survey sensor 7 slowly flexible, produce axial displacement, guarantee the accuracy of this device choosing pad.
Measuring table 8 and base 9, described measuring table 8 is fixedly mounted on the axle center of base 9, measuring table 8 is as the measurement component matching with survey sensor 7, both be arranged in the inner ring of bearing, base 9 with on pressure head 6, be all provided with a supporting surface matching with the outer face of bearing, select pad assembling for time, as shown in Figure 3, base 9 is leaned against to the outer face of drive bevel gear rear bearing 3, pressure head 6 leans against the outer face of drive bevel gear front bearing 1.
Utilizing this device to select in pad operation, first select the standard cushion block 10 that a thickness is known as H, the thickness H of requirement standard cushion block 10 is greater than the intrinsic clearance distance h between drive bevel gear front bearing 1 and the inner ring end face of drive bevel gear rear bearing 3, first as shown in Figure 3, standard cushion block 10 is placed between drive bevel gear front bearing 1 and the inner ring end face of drive bevel gear rear bearing 3, slowly drive survey sensor 7 to depress pressure head 6, until survey sensor 7 contacts with measuring table 8, obtain demarcating shift length A, again standard cushion block 10 is taken out, as shown in Figure 4, again slowly drive survey sensor 7 to depress pressure head 6, until survey sensor 7 contacts with measuring table 8, obtain without cushion block shift length B, intrinsic clearance distance h=H-(A-B).Then the intrinsic clearance distance that obtained and needed pretightning force can be selected the pad of respective thickness.
