Embodiment Construction

[0031] Below in conjunction with accompanying drawing, the embodiment of technical scheme of the present invention is described in detail:

[0032] According to an embodiment of the present application, such as figure 1 As shown, the long telescopic cardan shaft provided by this solution includes a spline set 1, a spline shaft 3 and a spline 8 set in the spline set 1, and a spline set on the spline set 1 and the spline The balance groove 6 on the shaft 3; the spline 8 is also sleeved outside the spline shaft 3; the spline set 1 includes a spline sleeve 7, and a fork that is connected to the spline sleeve 7 through a seam positioning connection Head 10.

[0033] Both the spline shaft 3 and the spline sleeve 7 are connected with the upper cross shaft of the cross pack 4, and the upper cross shaft of the cross pack 4 is also connected with the flange 5 to play the role of connection and fixation.

[0034] Such as Figure 4 As shown, the spline sleeve 7 and the fork head 10 in ...

Abstract

The invention discloses a long telescoping cardan shaft. The long telescoping cardan shaft comprises a spline housing set, a spline and balancing grooves, wherein the spline is arranged inside the spline housing set and outside a spline shaft, and the balancing grooves are formed in the spline housing set and the spline shaft. The spline housing set comprises a spline housing, a jaw which is in positioning connection with the spline housing through a spigot, a reamed hole bolt and a nut. According to the long telescoping cardan shaft, the spline housing and the spline shaft are matched through the spline, and long telescoping torque transmission of an SWP-type universal coupling is achieved; and under the adjusting action of balancing blocks, the cardan shaft can still guarantee the dynamic equilibrium during long telescoping torque transmission.

Description

technical field [0001] The invention belongs to the technical field of universal joints, and in particular relates to a long telescopic universal joint shaft. Background technique [0002] The cross-shaft universal joint is a general-purpose transmission base. Its main feature is that it can connect two transmission shafts that are not on the same axis, and can reliably transmit torque and motion. It has high load-bearing capacity and long service life. , stable operation, no noise, large amount of axial compensation, easy maintenance and so on. [0003] There are four types of cross shaft cardan shaft couplings according to their bearing fixing methods: SWP type (split bearing seat), SWZ type (integral bearing seat), SWC type (integral fork head) and SWB type (half fork). In our country, SWP type, SWC type and SWZ type have formulated industry standards, formed specialized production, and achieved good economic and social benefits. [0004] However, the expansion and cont...
