Description
Technical field
The utility model belongs to transmission shaft technical field, particularly relates to a kind of New-type transmission shaft possessing overload protection function.
Background technique
Existing transmission shaft adopts the bolt of 4 bolts or more to be connected with gearbox; and when tighting a bolt; need certain torque requirement; this just needs special instrument and detection facility; in use, after exceeding certain load (exceeding prescribed torque), need by disconnecting power source simultaneously; overload protection is carried out to the equipment of some terminal costliness, and current existing transmission shaft cannot carry out overload protection.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and provides a kind of installation simple and convenient, possesses the New-type transmission shaft of overload protection function simultaneously.
The purpose of this utility model has been come by following technical solution.This New-type transmission shaft, comprises central siphon, and the side of this central siphon is connected with universal joint, slip yoke and oil nozzle, opposite side is connected with weld yoke, clevis and land, be provided with internal spline in described land, the external diameter of the right outside circle of land is provided with a ring recess, and this groove offers the first pin-and-hole; The axle of the gearbox splined shaft coordinated with this land is provided with a circle external splines on the surface, and gearbox splined shaft offers the second pin-and-hole; Land to coordinate fixing and circumference to locate by internal spline with the external splines of gearbox splined shaft, be placed with spring pin in the first pin-and-hole and the second pin-and-hole are heavily incorporated in, the groove that the right outside circle of land is offered is built with the jump ring preventing spring pin from coming off in pin-and-hole.The left outside circle of described land is connected with the inner hole of clevis, simultaneously between the endoporus of the left outside circle of land and clevis, install one and enclose bearing steel ball, and adopt two bolts by land and clevis locked, bolt is equipped with the self-locking nut preventing bolt falling.
The beneficial effects of the utility model are: install simple and convenient; without the need to special instrument and detection facility; novel structure is reliable; when after appearance overload; bolt fracture only between clevis and land, only need change bolt, just can recover the original function of transmission shaft; possess overload protection function, can overload protective function be played to the equipment of some terminal costliness.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Label in accompanying drawing is respectively: 1, central siphon; 2, universal joint; 3, slip yoke; 4, oil nozzle; 5, weld yoke; 6, clevis; 7, land; 8, gearbox splined shaft; 9, spring pin; 10, jump ring; 11, bearing steel ball; 12, bolt; 13, self-locking nut; 61, endoporus; 71, internal spline; 72, the right outside circle of land; 73, groove; 74, the first pin-and-hole; 75, the left outside circle of land; 81, external splines; 82, the second pin-and-hole.
Embodiment
Below in conjunction with accompanying drawing, detailed introduction is done to the utility model: as shown in accompanying drawing 1,2, the utility model comprises central siphon 1, the side of this central siphon 1 is connected with universal joint 2, slip yoke 3 and oil nozzle 4, opposite side is connected with weld yoke 5, clevis 6 and land 7, internal spline 71 is provided with in described land 7, the external diameter of the right outside circle 72 of land is provided with a ring recess 73, and this groove 73 offers the first pin-and-hole 74; The axle of the gearbox splined shaft 8 coordinated with this land 7 is provided with a circle external splines 81 on the surface, and gearbox splined shaft 8 offers the second pin-and-hole 82; Land 7 is coordinated with the external splines 81 of gearbox splined shaft 8 by internal spline 71 to be fixed and circumferentially to locate, spline fitted rises to bear bears torsional interaction, spring pin 9 is placed with in first pin-and-hole 74 and the second pin-and-hole 82 are heavily incorporated in, by land 7 and gearbox splined shaft 8 locked (playing axially locating), the groove 73 that the right outside circle 72 of land is offered is built with the jump ring 10 preventing spring pin from coming off in pin-and-hole.
The left outside circle 75 (playing bearing inner race effect) of described land is connected with the endoporus 61 (playing bearing outer ring effect) of clevis 6, simultaneously between the endoporus 61 of the left outside circle 75 of land and clevis 6, install one and enclose bearing steel ball 11, the similar bearing of cooperating structure, and adopt two bolts 12 by land 7 and clevis 6 locked, bolt 12 is equipped with the self-locking nut 13 preventing bolt falling.When transmission shaft normally works, the moment of torsion transmission between land and clevis is transmitted (land, transfixion between steel ball and clevis) by two bolts.
Overload protection function of the present utility model is embodied in: after the moment of torsion transmitted exceedes the moment of torsion of regulation; two bolts 12 can be cut off by moment of torsion; clevis 6 and land 7 rotate by the bearing steel ball 11 between them; make moment of torsion cannot be delivered to clevis 6 end from land 7; thus to equipment below, play a protective role.Again, after changing two bolts 12, transmission shaft recovers again its original function.
The utility model is not limited to above-mentioned mode of execution; no matter do any change on its shape or material are formed; every employing structural design provided by the utility model, is all one distortion of the present utility model, all should thinks within the utility model protection domain.
