Description
Technical Field
The utility model relates to a cross axle type universal joint specifically is the external axial extending structure of cross axle type universal joint.
Background
As shown in the attached drawing 1, two ends of the existing universal joint pin type universal coupling are connected and fixed with the outside through connecting handles respectively, and the middle position of the universal joint pin type universal coupling is matched through a spline pair, so that the axial telescopic effect is achieved. The telescopic effect is mainly used for reducing the installation or operation difficulty in the installation or operation process.
However, the structure has the problems that the spline shaft and the spline sleeve realize the transmission effect through clearance fit, when the joint of the spline shaft and the spline sleeve is positioned at the integral middle position of the coupler, the outer diameter jumping error of the clearance is amplified by multiple times in the transmission process, and the structure has higher comprehensive cost, heavy comprehensive installation and maintenance and is easy to cause slipping accidents.
Disclosure of Invention
The utility model discloses the main technical problem who solves provides the external axial extending structure of cross axle type universal joint.
The utility model discloses the technical scheme who solves its technical problem and adopt is: the external axial telescopic structure of the cross-axle type universal coupling comprises a body, and a first connector and a second connector which are respectively positioned at two ends of the body, wherein the first connector is fixedly connected with the outside, and a spline sleeve used for being connected with the outside is arranged on the second connector.
The structure in this application has also contained the flexible function of axial, for among the prior art, the junction is located the intermediate position, the junction in this application is located the second catcher and the outside junction for the position of junction forms external effect, and is more convenient, safety in installation, use, maintenance process, and it is better to adopt this kind of structure to set up comprehensive operation effect, and comprehensive cost is cheaper, makes the vice driven error of cooperation back of spline reduce moreover.
Wherein, first catcher is interference fit with the outside.
Through interference fit's setting, improve the connection effect between first catcher and the outside.
Wherein, be equipped with connecting axle, two flange jaw and two welding jaws on the body, two welding jaws of connecting axle intercommunication, the connecting axle is hollow structure, and the welding jaw passes through the flange jaw and is connected with first catcher or second catcher.
Adopt hollow connecting axle setting for holistic quality reduces, further improves holistic installation and maintenance's convenience, security.
Wherein, the connecting shaft is welded with the welding fork head.
Through welded connection's mode for form firmly fixedly between connecting axle and the welding jaw, prevent to take place to drop.
Wherein, the flange jaw is fixed with first catcher or second catcher through bolted connection.
Through the arrangement of the bolts, the flange fork head and the first catcher or the second catcher form a linkage connection structure.

Detailed Description
Example 1:
referring to fig. 2-3, the external axial telescopic structure of the universal joint cross comprises a body 1, a first catcher 21 and a second catcher 22.
The body 1 comprises a connecting shaft 11, two flange forks 12 and two welding forks 13, wherein the connecting shaft 11 is of a hollow structure, namely the connecting shaft 11 is arranged in a hollow manner, and the wall thickness of the connecting shaft 11 can be selected according to actual requirements.
Two ends of the connecting shaft 11 are respectively connected with two welding forks 13, in this embodiment, the connecting shaft 11 preferably adopts a welding connection mode, so that the effect of connecting and fixing between the welding forks 13 and the connecting shaft 11 is realized, and the connecting shaft 11 and the welding forks 13 are firmly fixed in a welding connection mode to prevent falling. It should be noted here that the connecting shaft 11 is integrally formed, and the connecting shaft 11 does not axially extend or contract.
The welding fork 13 is connected to the first receiving portion 21 or the second receiving portion 22 through the flange fork 12, and here, specifically, the two welding forks 13 and the two flange forks 12 form two sets of structures, one of the two sets of structures is connected and fixed to the first receiving portion 21, and the other set of structure is connected and fixed to the second receiving portion 22. Here, the welding fork 13 and the flange fork 12 are also fixed in a connecting manner, and the fixing structure is the prior art, so the description in this embodiment is not repeated.
The flange jaw 12 is the same as the structure between two spigots, and is all fixed through bolted connection, is equipped with the reamed hole promptly on the flange jaw 12, all is equipped with the reamed hole on first spigots 21 and the second spigots 22, and the bolt realizes the fixed effect of being connected between flange jaw and first spigots 21 or the second spigots 22.
The first catcher 21 is in interference fit with the outside. Through interference fit's setting, improve the connection effect between first catcher 21 and the outside for first catcher 21 forms firmly fixed structure with the outside, can not take place the axial between the two and stretch out and draw back. The outer part here refers in particular to the structure that cooperates with the coupling in the installation environment.
The second connector 22 is provided with a spline sleeve 221, the spline sleeve 221 is used for being matched with an external spline shaft, the axial telescopic sliding and radial linkage effects between the spline sleeve 221 and the external spline shaft are achieved, and the external axial telescopic effect is formed due to the arrangement of the structure. Here, the spline housing 221 is provided with a plurality of grooves 2211 distributed in a circumferential array.
The structure in this application has also contained the flexible function of axial, for among the prior art, the junction is located the intermediate position, the junction in this application is located second catcher 22 and outside junction for the position of junction forms external effect, it is more convenient, safety in installation, use, maintenance process, it is better to adopt this kind of structure to set up comprehensive operation effect, comprehensive cost is cheaper, and make the driven error of spline pair cooperation back reduce moreover.
