The wear-resistant roller comprises a surface layer and a bottom layer, wherein the surface layer is bonded on the front surface of the bottom layer, wear-resistant strips are arranged on two sides of the back surface of the bottom layer, the wear-resistant strips are attached to the end surface of the roller, and a plurality of bending grooves are formed in the side walls of two sides of each wear-resistant strip in the height direction of the wear-resistant strip. Be equipped with crooked groove in the both sides of wear-resisting strip, when the hold-in range passes through the cylinder crooked, the lateral wall laminating in crooked groove for crooked easier, deformation through crooked groove makes can not produce stress at crooked in-process hold-in range, thereby protects the hold-in range can not produce the crack when crooked, prolongs the life of hold-in range.

Description

Synchronous belt

Technical Field

The utility model relates to an improvement of transmission band especially relates to the improvement of hold-in range.

Background

The hold-in range is a conveyer belt that transmission in-process is used commonly, finds its material harder in the use, therefore the easy fracture that appears of flexion especially in bending process when using to influence the life of hold-in range, and easy wearing and tearing with the one side that rotates the rod contact in its use lead to this side to appear wearing and tearing overweight, influence the life of hold-in range.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a hold-in range which is not easy to crack and has long service life.

The utility model discloses a following technical scheme realizes: the synchronous belt comprises a surface layer and a bottom layer, wherein the surface layer is adhered to the front surface of the bottom layer through hot melting, wear-resistant strips are arranged on two sides of the back surface of the bottom layer, the wear-resistant strips are attached to the end surface of the roller, and a plurality of bending grooves are formed in the height direction of the wear-resistant strips on the two sides of the wear-resistant strips.

A plurality of grooves are uniformly distributed on the back of the bottom layer along the width of the bottom layer, and the bending grooves on the opposite side walls of the wear-resistant strips are communicated with the grooves in a one-to-one correspondence mode.

The bottom layer is provided with a plurality of planting bars along the width direction of the bottom layer, and the planting bars extend along the length direction of the bottom layer.

The section of the bending groove is trapezoidal or circular arc.

Compared with the prior art, the utility model discloses when using, the plane at bottom place is actually surpassed to wear-resisting strip, that is to say in the in-service use in wear-resisting strip and cylinder direct contact, bottom individual top layer all not with the cylinder contact, therefore can not produce wearing and tearing, and be equipped with crooked groove in wear-resisting strip's both sides, when the hold-in range passes through the cylinder and is crooked, the lateral wall laminating in crooked groove, it is easier to make crooked, deformation through crooked groove makes can not produce stress at crooked in-process hold-in range, thereby the protection hold-in range can not produce the crack when crooked, the life of extension hold-in range.

Drawings

FIG. 1 is a schematic structural view of the present invention;

in the figure: 1. a surface layer; 2. a bottom layer; 3. wear resistant strips; 31. a curved groove; 32. a groove; 4. and (5) planting the steel bars.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1, the synchronous belt comprises a surface layer 1 and a bottom layer 2, wherein the surface layer 1 is bonded on the front surface of the bottom layer 2 in a hot melting mode, wear-resistant strips 3 are arranged on both sides of the back surface of the bottom layer 2, the wear-resistant strips 3 are attached to the end surface of the drum, a plurality of bending grooves 31 are formed in the side walls of both sides of each wear-resistant strip 3 along the height direction of each wear-resistant strip 3, and the sections of the bending grooves 31 are trapezoidal or arc-shaped. When using, wear-resisting strip 3 actually exceeds the plane at bottom 2 place, that is to say in-service use in-process wear-resisting strip 3 and cylinder direct contact, bottom 2 and top layer 1 all do not all contact with the cylinder, therefore can not produce wearing and tearing, and be equipped with crooked groove 31 in wear-resisting strip 3's both sides, when the hold-in range passes through the cylinder crooked, the lateral wall laminating in crooked groove 31, it is easier to make crooked, deformation through crooked groove 31 makes the hold-in range can not produce stress in crooked in-process, thereby the protection hold-in range can not produce the crack when crooked, the life of extension hold-in range.

A plurality of grooves 32 are uniformly distributed on the back surface of the bottom layer 2 along the width of the bottom layer 2, and the bending grooves 31 on the opposite side walls of the wear-resistant strips 3 are communicated with the grooves 32 in a one-to-one correspondence manner. When crooked 31 grooves, the fritter is separated into by recess 32 to bottom 2 for whole bottom 2 is the track and hits, and bottom 2 is crooked folding along recess 32 when crooked, avoids appearing hard folding, thereby makes the hold-in range can not be because of crooked folding crackle, extension hold-in range life.

The bottom layer 2 is provided with a plurality of planting bars 4 along the width direction of the bottom layer 2, and the planting bars 4 extend along the length direction of the bottom layer 2. The 4 parts of bar planting make whole hold-in range have good compressive property and tensile properties, promote the ductility of hold-in range.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
