Abstract
The utility model relates to an extendable square universal joint, which is mainly characterized in that the universal joint consists of a middle part, a driving part and a driven part, the middle part is a foursquare hole sleeve, and one end of the driving part and one end of the driven part respectively extend into a foursquare hole of the middle part. The universal joint can not only transmit torque force of two different shafts but generate a certain axial or radial displacement between the two transmitting shafts.
Description
Technical field:
The utility model relates to a kind of universal joint, particularly a kind of scalable square universal joint.
Background technique:
Universal joint is the coupling that is used for transmitting different axis two axle movements.Common universal joint can not stretch vertically.
Summary of the invention:
The purpose of this utility model is to provide a kind of scalable square universal joint.
The technical solution of the utility model is: a kind of scalable square universal joint, it is characterized in that: form by middleware, active coupling, driven coupling, middleware is square borehole jack, and initiatively the square small end of coupling and driven coupling extend into respectively in the square borehole jack of middleware.
Another kind of connecting mode of the present utility model is: middleware is square bar, and the two ends of square bar are stretched into respectively in the square hole of active big end of coupling and the big end of driven coupling.
The utility model is by middle coupling, the motion that not only can transmit the diaxon of different axis, and also two passing shafts can produce certain radial and axial displacement between middleware, can stretch between middleware.
Description of drawings:
Fig. 1 side of being shell type middleware connects schematic representation;
Fig. 2 side of being bar formula middleware connects schematic representation.
Among the figure: 1, middleware; 2, driving link; 3, driven member.
Embodiment:
As shown in Figure 1, the utility model is made up of middleware 1, driving link 2, driving link 3, middleware is square borehole jack, driving link joining end and driven member joining end stretch into respectively in the square borehole jack of middleware from two ends, and several angle mutually staggers, guarantee that simultaneously it is that face contacts that master and slave moving part respectively has two faces and middle cover, can slide along surface of contact.Master and slave moving part compensates radial and axial displacement along mutually perpendicular direction deflection and slip vertically.
As shown in Figure 2, the utility model is made up of middleware 1, driving link 2, driving link 3, middleware is square bar, the two ends of square bar are stretched into respectively in the square opening of the square opening of driving link and driven member, and the several angle that staggers mutually guarantees that simultaneously it is that face contacts that master and slave moving part respectively has two faces and middleware, can slide along surface of contact, master and slave moving part compensates radial and axial displacement along mutually perpendicular direction deflection and slip vertically.
Claims (2)
1, a kind of scalable square universal joint is characterized in that: be made up of middleware, active coupling, driven coupling, middleware is square borehole jack, and initiatively the square small end of coupling and driven coupling extend into respectively in the square borehole jack of middleware.
2, universal slip joint according to claim 1 is characterized in that: middleware is square bar, and the two ends of square bar are stretched into respectively in the square hole of active big end of coupling and the big end of driven coupling.
