Abstract

The utility model discloses a ring gear pair roller, roll body including two mutual interlocks are in the same place, the surface of roll body is provided with the ring gear layer, just the ring gear layer is made by wear-resistant material, be equipped with a plurality of ring gear on the ring gear layer, the cross section of ring gear is the polygon of limit number more than or equal to 4, and the ring gear is about perpendicular to pair roller axis symmetry in the middle of the addendum, and the adjustment that increases material grain type, the broken throughput of increase are increased to the line speed difference between addendum and the tooth low through the ring gear layer, and this application adopts the setting of polygon ring gear to increase broken contact point simultaneously, and crushing efficiency is showing the improvement than triangle-shaped ring gear and circular ring gear, broken product granularity, and the grain shape qualification rate is high.

Description

Ring tooth pair roller

Technical Field

The utility model belongs to the technical field of broken mechanical equipment subassembly, in particular to ring tooth pair roller.

Background

The crushing device is widely applied in the industry and life at present, the crushing device is various and different, the crushing is realized by adopting the principle that a movable rotor and a fixed rotor are mutually rolled and crushed by various crushing devices at present, the crushing is also realized by adopting double-roller crushing, most of double rollers of the double-roller crusher are crushed by adopting a smooth double-roller extrusion mode at present, the double-roller crushing mode has the defect of small double-roller crushing area with the same diameter, and the double rollers are arranged symmetrically and have the same diameter, so the linear speed between the double rollers which move relatively is consistent, the particle shape of a product obtained by crushing the smooth roller is irregular, more defective products are generated, the defects of the device are continuously upgraded in 2017 and 2019 by the applicant, and the double rollers of 201720670610.1 curved-ring-tooth roller mill and 2019219844518 curved-ring-tooth double rollers are applied, although the technical problems are overcome, however, the tooth surface of the crusher is arc-shaped, so that the crusher has a larger contact surface with stone materials in the crushing process, and the crusher can crush the stone materials only by using larger force, namely, the crusher is required to provide higher power; in order to further optimize the crushing forming effect of the equipment, the two applications upgrade the section of the ring tooth into a triangle or a trapezoid from a circle, but the applicant further develops the design in order to increase the crushing area, which is determined in consideration of the relative crushing area after the roll forming.

SUMMERY OF THE UTILITY MODEL

The technical task of the utility model is to provide a ring tooth pair roller to the above prior art is not enough.

The utility model provides a technical scheme that its technical problem adopted is a ring gear pair roller, roll body including two mutual interlocks together, the surface of roll body is provided with the ring gear layer, just the ring gear layer is made by wear-resisting material, be equipped with a plurality of ring gear on the ring gear layer, the cross section of ring gear is the polygon of limit number more than or equal to 4, and the effectual contact point that has increased ring gear and material of polygon ring gear design can effectual improvement crushing efficiency, and the ring gear is about perpendicular to pair roller axis symmetry in the middle of the tooth top.

Further as the preferred scheme of the utility model, the cross section of annular tooth is square.

Further as the utility model discloses preferred scheme, the cross section of annular tooth is the rectangle.

Further as the utility model discloses an optimal scheme, the cross section of annular tooth is the polygon regular polygon that the limit number is greater than 4, and convex annular tooth cross-section is the partly of symmetry in the regular polygon promptly.

Further as the utility model discloses a preferred scheme, the recess shape between two adjacent annular teeth is the same with the cross-sectional shape of annular tooth, the clearance size between the annular tooth of the roll body of mutual interlock equals, and two effective assurance pair rollers interlock back, the clearance between the relative rotating ring tooth of pair roller is unchangeable, can effectual improvement grain shape yield.

The utility model has the advantages that:

1. reasonable in design, simple structure, easy to assemble the maintenance, the durability is high, can effectual reduction in production cost.

2. Simultaneously, the design of the double-roll polygonal ring teeth is adopted to effectively increase the crushing area, and the different positions between the ring teeth have online speed difference, so that the rotation of the stone materials picked up by the ring teeth is increased, the grain shape of the product is regular, meanwhile, the cross section of the ring teeth is in a regular polygon shape, more stone materials can be crushed when larger stone materials are crushed, the stone materials are in approximate point contact, and the larger stone materials are crushed more easily, so that the production efficiency is further improved.

Detailed Description

The working process of the present invention is explained in detail with reference to the accompanying drawings 1-4:

example 1

The utility model provides a ring gear pair roller, includes two roll bodies 1 that interlock each other and be in the same place, the surface of roll body 1 is provided with ring gear layer 2, just ring gear layer 2 is made by wear-resistant material, be equipped with a plurality of ring gear 3 on ring gear layer 2, the cross section of ring gear 3 is the polygon of limit number more than or equal to 4, and ring gear 3 about the middle perpendicular to roll body 1 axis symmetry of addendum.

Further preferably, the cross section of the ring-shaped teeth 3 is square.

Further as the utility model discloses a preferred scheme, the recess shape between two adjacent annular teeth 3 is the same with annular teeth 3's cross sectional shape, the clearance size between 3 of the annular teeth of roll body 1 of mutual interlock equals.

Example 2

Further preferably, the cross section of the ring-shaped teeth 3 is square.

Example 3

Further as the preferred scheme of the utility model, the cross section of annular tooth 3 is the polygon regular polygon that the limit number is greater than 4.
