Abstract
The utility model provides a balance-tab free regulating bearing for the drive axle of an automobile, comprising a needle bearing and a regulating screw. The center of the end face of the needle bearing is provided with a thread hole via which the regulating screw winds around the needle bearing. The balance-tab free regulating bearing for the drive axle of an automobile is adopted to be installed in the pin hole of a flange yoke replacing the present bearing, and simultaneously the balance-tab is cancelled. A cross shaft is butted and pressed by rotating the regulating screw, so as to eliminate the moving space of the cross shaft in the pin hole and regulate the center of gravity of the driving shaft, and the non-balance of the driving shaft is reduced, so the driving shaft rotates stably.
Description
Technical field
The utility model relates to bogie and passenger vehicle transmission shaft, especially propeller-shaft do not have balancing patch adjusting bearing.
Background technology
At present, bogie and passenger vehicle transmission shaft be mainly by central siphon, joint yoke, and prominent circle fork, the sleeve pipe fork, center cross, needle bearing is formed.At joint yoke, prominent circle fork, needle bearing and center cross are blocked by jump ring or flat clamp in the earhole outside of sleeve pipe fork, do not allow it pass earhole, do not regulate the function of transmission shaft centre of gration.Because center cross is gapped in earhole, it can be in earhole play, when transmission shaft work, centre-of gravity shift caused instability and car body to shake.On transmission shaft, add balancing patch at present and make it balance, but this balance not stable.
Technology contents
In order to solve present propeller-shaft kinetic balance value height, the rotation problem of unstable, the utility model proposes propeller-shaft and do not have balancing patch adjusting bearing, comprise needle bearing, set screw, it is characterized in that: the end face center of needle bearing is provided with tapped bore, and set screw is spun on the needle bearing by tapped bore.
Adopt above-mentioned propeller-shaft not have balancing patch and regulate the existing bearing installation of bearing replacement on earhole, adopt the hole to locate with jump ring, cancelled balancing patch simultaneously, the head and the cross axis faces of described set screw are corresponding, by rotation set screw roof pressure center cross, make center cross at joint yoke, displacement in the earhole of flange york and sleeve pipe fork, thereby eliminate the play gap of center cross in earhole and adjust the transmission shaft center of gravity, reduce the transmission shaft amount of unbalance, transmission shaft under high rotating speed the kinetic balance value stabilization in 50g/cm, the kinetic balance value is little, and the transmission shaft spin stabilization improves the stability of automobile at running on expressway like this, avoid on transmission shaft, adding the shortcoming that mode that balancing patch makes it balance exists fully, need on propeller-shaft, not add balancing patch.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is that the utility model is at propeller-shaft installation site scheme drawing
Fig. 4 is the assembling scheme drawing of the utility model on transmission shaft.
The specific embodiment
As shown in Figure 1, 2, set screw 2 is spun on the needle bearing 1 by the supercentral tapped bore 3 of the end face of needle bearing 1, is provided with scale indication 4 at described tapped bore periphery.
As shown in Figure 3, the vapour propeller-shaft does not have balancing patch and regulates bearing and be installed in the joint yoke 6 of propeller-shaft 5 or the earhole of flange york 7.
As shown in Figure 4, in the earhole 9 of the flange york 6 of at first center cross 8 being packed into, again with needle bearing 1 by earhole by packing into outward, the two ends of supports spider 5, set screw 2 is spun on the needle bearing 1, is packed in the earhole jump ring groove 11 with jump ring 10 in the hole at last, blocks needle bearing 1.Regulate center cross 8 centers by rotation set screw 2, thereby regulate the transmission shaft center of gravity.
Dynamic balance adjusting method: after transmission shaft was done experiment of dynamic balancing and drawn amount of unbalance, the operator need not to add balancing patch, but according to the rotation amount of the pitch conversion set screw of amount of unbalance and set screw, can adjust accurately and conveniently by the scale indication.
In reality is adjusted, get final product by rule of thumb, the kinetic balance value both can be less than the 50g/cm requirement after generally transferring twice.
The dress propeller-shaft does not have the transmission shaft experiment of dynamic balancing result that balancing patch is regulated bearing:
The N time experiment kinetic balance value g/cm phase place (degree)
1 64.2 30.9
2 40.2 31.7
3 27.8 31.6
4 11.4 30.3
As the table experimental result as can be known, transmission shaft kinetic balance steady quality, variable is in 50g/cm, and the kinetic balance value is more and more littler.
Claims (2)
1, propeller-shaft does not have balancing patch adjusting bearing, comprises needle bearing, set screw, and it is characterized in that: the end face center of needle bearing is provided with tapped bore, and set screw is spun on the needle bearing by tapped bore.
2, propeller-shaft according to claim 1 does not have balancing patch adjusting bearing, it is characterized in that: described tapped bore periphery is provided with the scale indication.
