Abstract
The invention relates to a heavy truck transmission shaft with a rapid dynamic balance calibration structure. The heavy truck transmission shaft comprises a transmission shaft formed by axially connecting a spline sleeve and a shaft tube; balance rings are respectively arranged on the spline sleeve and the shaft sleeve; the balance ring comprises two semicircular rings, annular slots are formed on the semicircular rings along the circumference, the cross section of the annular slot is T-shaped and is provided with sliding blocks in a matching way, and the position of the sliding block can be slidingly adjusted on the annular slot; bolts fix balancing blocks onto the semicircular rings after penetrating through mounting holes on the sliding blocks through the matching connection with the balance blocks; an inward groove is formed at the inner wall of one end of the semicircular ring, and an outwards convex block is formed at the inner wall of the other end of the semicircular ring; and the groove on one semicircular ring is correspondingly matched with the convex block on the other semicircular ring, and threaded holes of the groove are in threaded connection with through holes on the convex block. By the heavy truck transmission shaft, multiple disadvantages caused by fixing the balance blocks in a welding way can be effectively overcome, the dynamic balance test of the transmission shaft can be more rapidly and exactly executed, and the transmission shaft is flexible.
Description
Technical field
The invention belongs to the Universal drive technical field, be specifically related to a kind of heavy duty truck transmission shaft.
Background technology
Along with the fast development of domestic express highway and the raising of people's economic level, the client improves constantly the car load travelling comfort, the high speed performance of automobile more and more is subject to the great attention of auto trade, enterprise, and the high-speed balancing of propeller-shaft affects one of key factor of automobile high-speed performance just.Heavily blocking the transmission shaft kinetic balance is by improving the mass distribution of driving-shaft assembly self, reduce because the periodic vibration that rotatablely moves and bring, minimizing is called static unbalance when existing owing to the moment of couple, the kinetic balance of transmission shaft mainly refers under transmission shaft static unbalance state by the method for balancing patch is installed at the transmission shaft two ends, the mass cg of trying hard to make assembly is realized static balance as much as possible by centre of gration.But when rotor, two centnifugal force equal and opposite in directions, opposite direction, the couple that partners, this moment of couple will cause that two side bearings produce periodically variable dynamical reaction.The overbalance that this transmission shaft that is caused by the moment of couple vibrates is exactly the unbalance dynamic of transmission shaft self.As mentioned above, the main employing at the two ends of transmission shaft installed balancing patch at present, so that the whole balance that realizes centnifugal force and the moment of couple of transmission shaft.And for the installation method of balancing patch, most enterprises adopts the mode of welding.But welding manner has many unfavorable factors, and is specific as follows: 1. welding causes the distortion of transmission shaft easily, thereby has introduced new unbalanced factor; 2. each quality of scolder of using can't accurately be controlled in the welding process, thereby is unfavorable for offsetting more accurately unbalance mass; 3. balance block is welded on can't effectively make behind the errors present and remedies.
Summary of the invention
The deformation of transmission shaft that exists for the transmission shaft that solves existing welding balancing patch, produce the problem such as unbalanced factor, the invention provides a kind of heavy duty truck transmission shaft with quick kinetic balance calibration structure.
Heavy duty truck transmission shaft with quick kinetic balance calibration structure comprises by splined sleeve and the coaxial transmission shaft that connects to form of central siphon, and being connected the outer end and connecting respectively jaw in the outer end of splined sleeve with central siphon, is respectively equipped with balance ring on splined sleeve and the central siphon; Described balance ring comprises two semicircle rings, and the semicircle ring is semi-annular shape, is provided with annular groove along circumference on it, and the cross-sectional plane of annular groove is T-shaped groove, and the cooperation of annular groove place is provided with slide block, and slide block can slide at annular groove and adjust the position; Offer mounting hole on the slide block, bolt passes mounting hole on the slide block by with being connected of balance block balance block being fixed on the semicircle ring, and balance block is positioned at the inner periphery place of semicircle ring; One end inwall of semicircle ring is provided with the groove that concaves, and groove is provided with tapped bore radially, and the other end inwall place of semicircle ring is provided with the projection of outside projection, offers through hole radially on the projection; Groove on semicircle ring and the projection corresponding matching on another semicircle ring, the tapped bore of groove and the through hole on the projection are connected by screw, and are fixed by screws on the splined sleeve or on the central siphon.
The cross-sectional plane of described annular groove is T-shaped groove, and balance block is positioned at the T-shaped groove on the semicircle ring.
The present invention effectively overcomes many unfavorable that welding manner stable equilibrium piece brings, so that more rapid, the precision of the enforcement of the dynamic balancing test of transmission shaft, and more have alerting ability.Rapid being embodied in, the use of balance ring so that the fixing mode that does not need to adopt welding of balance block, thereby has been simplified operation, saved the time; Do not use the mode stable equilibrium piece of welding, thereby can not cause the distortion of axle and introduce uncertain quality, because, the weight of the balance block on two balance rings, semicircle ring, slide block and installation site all are to determine by accurate Calculation at the design initial stage, thereby, in the actual installation process, except the circumferential position of balance block and slide block was adjustable, other factors all immobilized.Utilize the annular groove on balance ring surface, the random circumferential position of adjustment piece is so that dynamic balancing test has higher alerting ability, even in the undesirable situation of first regulating effect, also can make amendment easily.

The specific embodiment
Below in conjunction with accompanying drawing, by embodiment the present invention is further described.
Referring to Fig. 1, heavy duty truck transmission shaft with quick kinetic balance calibration structure comprises by splined sleeve 2 and the central siphon 3 coaxial transmission shafts that connect to form, the outer end of being connected with central siphon in the outer end of splined sleeve 2 is connecting respectively jaw 5, on splined sleeve 2 and the central siphon 3 balance ring is housed respectively.Balance ring comprises two semicircle rings 1, semicircle ring 1 is semi-annular shape, be provided with annular groove 4 along circumference on it, the cross-sectional plane of annular groove 4 is T-shaped, the cooperation of annular groove 4 places is equipped with slide block 7, and slide block 7 can slide at annular groove 4 and adjust positions, offer mounting hole on the slide block 7, bolt passes mounting hole on the slide block 7 by with being connected of balance block 6 balance block 6 being fixed on the semicircle ring 1, and balance block 6 is positioned at the inner periphery place of semicircle ring 1.One end inwall of semicircle ring 1 is provided with the groove that concaves, and groove offers tapped bore radially, and the other end inwall place of semicircle ring 1 is provided with the projection of outside projection, offers through hole radially on the projection; Groove on semicircle ring and the projection corresponding matching on another semicircle ring, the tapped bore of groove and the through hole on the projection are connected by screw, and are fixed by screws on the splined sleeve or on the central siphon.
