Abstract
The invention discloses an improved end cover for a universal joint pin type universal coupler. The end cover body takes the shape of a round disc; arced flanges are symmetrically arranged on the outer side surface of the end cover body; a flat column is arranged on one side of the end cover body; the diameter of the column is the same as that of the round-disc-shaped end cover body; an inclined surface is arranged from the top surface to each of the two sides of the column; the two inclined surfaces are arranged symmetrically. The improved end cover is simple in structure, reasonable in design, low in manufacturing cost, and capable of eliminating a gap between the end cover body and a flange fork, internal space of the end cover body is effectively utilized, and the overall rigidity of the end cover body is improved.
Description
Technical field
The invention belongs to Hooks coupling universal coupling technical field, relate in particular to a kind of universal coupling with spider modified model end cap.
Background technique
At present, universal coupling with spider has been widely used in the industries such as mine, metallurgy, chemical industry, boats and ships, transmits motion and moment of torsion between prime mover and working machine, in use will bear larger load and impact frequently.The trunnion journal of universal coupling with spider is arranged in the bearing hole of flange jaw, and cross shaft bearing seat outer end is bolted and is fixed with end cap, and end cap bears huge axial impact load.The end cap of tradition universal coupling with spider adopts disk-like structure mostly, and as shown in Figure 1, all there is reduction at end cap edge along the circumferential direction thickness, and approximately 1/2 trimming space does not utilize completely; And end cap outer is along the circumferential direction evenly equipped with tapped hole, end cap is firmly connected by the screw being arranged in each tapped hole with flange jaw, this requires when assembling, the moment of torsion that torque spanner applies each screw is identical, guarantee evenly fastening, therefore, higher to matching requirements, not easy to operate, and after the long-time use of end cap, the screw having damaged is not quick detachable.
Summary of the invention
For addressing the above problem, the object of this invention is to provide a kind of universal coupling with spider simple in structure, reasonable in design modified model end cap.
For achieving the above object, the present invention adopts following technological scheme:
A kind of universal coupling with spider modified model end cap, its end cap body is in the form of annular discs, end cap body outer side surface is symmetrically arranged with circular-arc flange, one side of end cap body is provided with a flattened cylindrical body, cylinder diameter is identical with discoid end cap body diameter, cylindrical body end face to both sides are respectively equipped with a ，Liang inclined-plane, inclined-plane and are arranged symmetrically with.
Described universal coupling with spider modified model end cap, each the circular-arc flange on its end cap body accounts for 1/4 circle of end cap body.
Described universal coupling with spider modified model end cap, is provided with circular counter bore on two circular-arc flanges on its end cap body.
Described universal coupling with spider modified model end cap, the circular-arc flange on its end cap body is embedded in the internal bore groove of flange jaw when end cap body is connected with flange jaw.
Described universal coupling with spider modified model end cap, when its end cap body is connected with flange jaw, the cylindrical body end face of end cap body protrudes from flange jaw 5～10mm.
Described universal coupling with spider modified model end cap, its cylindrical body end face is vertically installed with bolt hole.
Owing to adopting technological scheme as above, the present invention has following superiority:
This universal coupling with spider modified model end cap, it is simple in structure, reasonable in design, low cost of manufacture, circular-arc flange on end cap body is embedded in the internal bore groove of flange jaw, by being arranged on the jackscrew of flange jaw and end cap body junction, eliminate the gap between end cap body and flange jaw, guarantee that end cap firmly contacts in working order all the time with flange jaw; Because end cap is fixing, adopt jackscrew, cancelled tapped hole, end cap external diameter is reduced, the flange jaw endoporus matching also reduces, and has reduced difficulty of processing, has improved, and work efficiency, has reduced manufacture cost; The external side of flattened cylindrical of end cap body is comprised of two inclined-planes and the plane that approach turning circle, and inclined-plane and turning circle smooth transition guarantee beautiful shape; When end cap body is connected with flange jaw, the cylindrical body end face of end cap body protrudes from flange jaw 5～10mm, can effectively utilize end cap body interior space, improves end cap body integral rigidity, improves the life cycle of product.

Embodiment
Below by drawings and Examples, technological scheme of the present invention is described in further detail.
As shown in Figure 2,3, this universal coupling with spider modified model end cap, its end cap body 1 is in the form of annular discs, end cap body outer side surface is symmetrically arranged with circular-arc flange 3, each circular-arc flange accounts for 1/4 circle of end cap body, and a side of end cap body is provided with a flattened cylindrical body 2, and cylinder diameter is identical with discoid end cap body diameter, cylindrical body end face 6 to both sides are respectively equipped with 5, two inclined-planes, an inclined-plane and are arranged symmetrically with; Cylindrical body end face is vertically installed with bolt hole 7.
Circular-arc flange when end cap body is connected with flange jaw on end cap body is embedded in the internal bore groove of flange jaw, on two circular-arc flanges 3, be provided with circular counter bore 4, by jackscrew, end cap body and flange jaw are linked together, jackscrew is embedded in flange jaw.
Described universal coupling with spider modified model end cap, when its end cap body is connected with flange jaw, the cylindrical body end face of end cap body protrudes from flange jaw 5～10mm.
