Description

For bearing pin and the pin-and-hole of mobile crushing station

Technical field

The utility model relates to a kind of bearing pin, particularly relates to a kind of bearing pin for load-bearing and pin-and-hole.

Background technique

Existing bearing pin major part is all circular, although process more convenient, but in use, particularly for the cooperation having gap between bearing pin and pin-and-hole, bearing pin contacts seldom with pin-and-hole, is not suitable for carrying heavier load, for when carrying the load of rocking, as heavy for mobile crushing station etc. and when having the equipment rocked, can not effectively reduce and rock, affect the stability of equipment.

Summary of the invention

The technical problems to be solved in the utility model is to provide one significantly can improve bearing capacity, the bearing pin that effective minimizing equipment rocks, and applies to the heavy types such as mobile crushing station and has the pin of the equipment rocked to connect.

The technical solution of the utility model is: a kind of bearing pin for mobile crushing station and pin-and-hole, comprise bearing pin and pin-and-hole, and the cross-section of bearing pin is rhombus, and four angles of bearing pin are rounding; Pin-and-hole and bearing pin match, and two diagonal vertical of pin-and-hole are arranged, and two other diagonal angle of pin-and-hole is horizontally disposed with; The chamfer angle at two diagonal angles up and down of pin-and-hole is comparatively large, and the chamfer angle at two diagonal angles, left and right of pin-and-hole is less; The distance up and down between two diagonal angles of pin-and-hole is greater than the distance between two diagonal angles, left and right; Above pin-and-hole, the angle on two adjacent limits is 75 °, and about pin-and-hole, the angle on two adjacent limits is 105 °; The end of bearing pin is provided with cylindric bar, and the diameter of cylindric bar is slightly less than the cross section length of side of bearing pin, and cylindric bar is provided with circular hole; One end of bearing pin is provided with draw ring, and draw ring is stuck in the top of bearing pin, and draw ring can rotate around bearing pin top.

The beneficial effects of the utility model are: upper and lower two diagonal angles of bearing pin of the present utility model are all changed into Rouno Cormer Pregrinding Wheel, when carrying large load, upper and lower two diagonal angles can be avoided to produce stress and concentrate; The chamfering radian at two diagonal angles, left and right is less, is conducive to the laminating length and the area of contact that increase bearing pin and pin-and-hole; The cooperation of this bearing pins and rhombus pin-and-hole compared with the cooperation of circular pin hole, adds lifting surface area with common circular bearing pin, and distance between upper and lower two diagonal angles of this rhombus bearing pin is large, and bearing capacity is increased substantially; Simultaneously because the distance between diagonal angle, two, left and right is little, upper and lower two diagonal angles are less than the angle at two diagonal angles, left and right, be conducive to two sides and pin-and-hole before and after bearing pin to be adjacent to, rocking of equipment can be effectively reduced when carrying the equipment rocked, the stability of raising equipment, the maintenance frequency of minimizing equipment, the working life of extension device; One end of this bearing pin is provided with draw ring, facilitates bearing pin insert or extract pin-and-hole.

Embodiment

As shown in Figure 1, Figure 2 and Figure 3, a kind of bearing pin for mobile crushing station and pin-and-hole, comprise bearing pin 1 and pin-and-hole 2, and the cross-section of bearing pin 1 is rhombus, and four angles of bearing pin 1 are rounding, pin-and-hole 2 and bearing pin 1 match, and two diagonal vertical of pin-and-hole 2 are arranged, and two other diagonal angle of pin-and-hole 2 is horizontally disposed with, the chamfer angle at two diagonal angles up and down of pin-and-hole 2 is larger, the chamfer angle at two diagonal angles, left and right of pin-and-hole 2 is less, larger with the diagonal angle chamfering radian of pin-and-hole about 2 two bearing pins that diagonal angle is corresponding 1, when can effectively avoid bearing large load, upper and lower diagonal angle generation stress is concentrated, less with the diagonal angle chamfering radian of pin-and-hole about 2 two bearing pins that diagonal angle is corresponding 1, the bearing pin 1 matched through after pin-and-hole 2, two inclined-planes above pin-and-hole 2 naturally coordinate closely with bearing pin 1 under active force, the cooperation of this kind of bearing pin 1 and pin-and-hole 2 with common circular pin compared with the cooperation of circular pin hole, laminating length and the area of contact of bearing pin 1 and pin-and-hole 2 can be increased.The distance up and down between two diagonal angles of pin-and-hole 2 is greater than the distance between two diagonal angles, left and right, and the width about upper and lower height is greater than is conducive to bearing capacity and significantly improves.The angle on pin-and-hole 2 above two adjacent limits is 75 °, the angle on pin-and-hole about 2 two adjacent limits is 105 °, the angle at upper and lower two diagonal angles is greater than the angle at two diagonal angles, left and right, before and after being conducive to bearing pin 1 and pin-and-hole 2, two sides is adjacent to, and can effectively reduce rocking of equipment for when carrying the equipment rocked.The end of bearing pin 1 is provided with cylindric bar 6, and the diameter of cylindric bar 6 is slightly less than the cross section length of side of bearing pin 1, and cylindric bar 6 is provided with circular hole 7, cotter pin is inserted in circular hole 7, can prevent bearing pin 1 from scurrying out.One end of bearing pin 1 is provided with draw ring 3, and draw ring 3 is stuck in the top of bearing pin 1, and draw ring 3 can rotate around bearing pin 1 top, arranges draw ring 3 and facilitates bearing pin insert or extract pin-and-hole 2.

During use, after pin-and-hole 2 alignment of the pin-and-hole 2 on supporting leg top 4 and supporting leg bottom 5, then bearing pin 1 is pierced into the pin-and-hole 2 of alignment, two inclined-planes above pin-and-hole 2 under the effect of load naturally and bearing pin 1 fit tightly, there is between bearing pin 1 and pin-and-hole 2 very large area of contact, bearing capacity increases substantially, and simultaneously because two sides, front and back is all adjacent to, can effectively reduce rocking of equipment for when carrying the equipment rocked; Again cotter pin is inserted in the circular hole 7 on cylindrical bar 6, prevent bearing pin from scurrying out.
