Abstract
The utility model provides a round pin hub connection prevents that favourable turn constructs, belongs to mechanical transmission technical field, has solved rigidity in the use of round pin axle, has produced relative displacement's technical problem along with machine part, and the solution is: being provided with two junction of the edges of two sheets of paper pinholes about the axis direction symmetry on round pin axle and the pinhole contact surface, being provided with the locating pin in the junction of the edges of two sheets of paper pinhole, be provided with the mounting hole on the round pin axle head face, a round pin axle both sides terminal surface all is provided with the separation blade outward, is provided with the through -hole with the mounting hole position department of correspondence on the separation blade, and mounting screws passes the through -hole and sets up in the mounting hole, the mounting hole with mounting screws is threaded connection. The utility model provides a round pin hub connection rotation -proof structure on the one hand, sets up junction of the edges of two sheets of paper pinhole on pinhole and the epaxial contact surface of round pin, set up the standard setting round pin and realize the round pin axle prevent changeing in junction of the edges of two sheets of paper pinhole, on the other hand is selling the axle head fixed mounting circular retaining piece of portion, effectively prevents the axial float of round pin axle, and aesthetic property, practicality have been compromise to this structure, has stronger manufacturability and uses intensity.
Description
Technical field
The utility model belongs to technical field of mechanical transmission, and more particularly to a kind of bearing pin connects rotation-preventing mechanism.
Background technology
Bearing pin connection is widely used in the mechanized equipments such as lorry-mounted crane, and bearing pin connection is except bearing pin two ends band back-up ring
It is outer, other are all fixed pin shaft.Require that position is fixed during bearing pin use, do not produce relative displacement with machine components, this
It is accomplished by making bearing pin anti-rotation design, designs what anti-rotation alignment pin can be rotated with effectively solving bearing pin at bearing pin and pin-and-hole cooperation
Problem.
Utility model content
The technical problems to be solved in the utility model is：During bearing pin use position fix, not with machine components produce
The technical problem of relative displacement, the utility model provides a kind of bearing pin and connects rotation-preventing mechanism.
The utility model is achieved by the following technical programs.
A kind of bearing pin connects rotation-preventing mechanism, and it includes bearing pin, and bearing pin is penetrated in pin-and-hole, wherein：Bearing pin and pin-and-hole contact surface
On be symmetrically arranged with two junction of the edges of two sheets of paper pin-and-holes with regard to axis direction, alignment pin is provided with junction of the edges of two sheets of paper pin-and-hole, be provided with pin roll end face
Installing hole, outside the end face of bearing pin both sides catch is provided with, and position of mounting hole corresponding position is provided with through hole, mounting screw on catch
It is arranged in installing hole through through hole, the installing hole is to be threadedly coupled with the mounting screw.
Further, longest distance of the catch with diameter greater than two junction of the edges of two sheets of paper pin-and-hole edge lines.
The utility model has the advantages that compared with prior art.
The bearing pin connection anti-rotation structure that the utility model is provided, on the one hand, arrange on contact surface on pin-and-hole and bearing pin and ride
Key of joint hole, standard setting pin is arranged in junction of the edges of two sheets of paper pin-and-hole and realizes pin shaft anti-rotation；On the other hand, justify in end part of pin shaft fixed installation
Shape catch, effectively prevents the axial float of bearing pin, this structure from having taken into account aesthetic property, practicality, with stronger manufacturability and makes
Use intensity.

Specific embodiment
As shown in Fig. 1 ~ 4, a kind of bearing pin connects rotation-preventing mechanism, and it includes bearing pin 1, and bearing pin 1 is penetrated in pin-and-hole 2, its feature
It is：Setting in two junction of the edges of two sheets of paper pin-and-holes 3, junction of the edges of two sheets of paper pin-and-hole 3 is symmetrically arranged with bearing pin 1 and the contact surface of pin-and-hole 2 with regard to axis direction
There is alignment pin 4, alignment pin 4 realizes that bearing pin 1 is moved without spin relative to pin-and-hole 2.Installing hole 5, bearing pin are provided with the end face of bearing pin 1
Catch 6 is provided with outside 1 both sides end face, the position corresponding position of installing hole 5 is provided with through hole on catch 6, catch 6 is with diameter greater than two
The longest distance of the edge line of junction of the edges of two sheets of paper pin-and-hole 3, mounting screw 7 is arranged in installing hole 5 through through hole, the installing hole 5 and institute
Mounting screw 7 is stated to be threadedly coupled, in the end of bearing pin 1 rounded tabs 6 are fixedly mounted, effectively prevent axle of the bearing pin 1 in pin-and-hole 2
To play.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
It is any to be familiar with those skilled in the art in the technical scope that the utility model is disclosed in this, the change that can be readily occurred in
Or replace, all should cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be with the power
The protection domain that profit is required is defined.
