Abstract

The utility model discloses a joined arc tooth shaped V belt which is composed by a tensile rubber layer, a wire winding connection layer, a buffering layer, a wire winding strength layer and a directional short fiber compression rubber layer, the shape of the horizontal section of the belt body is the same with that of 2-8 parallelly joined V section, the top of the V section is provided with a plurality of continuous arc tooth shapes along the vertical axis direction of the belt body, the upper surface of the belt body is a smooth surface. The utility model is easy to control the length, small in bending stress, good in tensile property, high in wear resistance performance, convenient in using, and is difficult to cause the phenomena such as dither, flap, belt turnover and belt falling down.

Description

The arc toothed V band of joint group

The utility model relates to a kind of arc toothed V band of mechanically operated joint group that is used for, and belongs to driving belt

Technical field.

At present, its sectional shape of driving belt of the prior art all is single V-arrangement shape or rectangular configuration shape generally, these driving belt ubiquities of the prior art that flexural stress is big, tensility is low, are skidded easily, wear resistance is relatively poor, be prone to shake, bounce, turn over band or fall shortcoming such as band, particularly when many bands are used in combination, because the length dimension of its every band can not be just the same, therefore greatly reduce stability of transmission and reliability, and the difficulty that has increased the complexity of gearing and increased maintenance and adjusted.

The purpose of this utility model is: a kind of length unanimity, the arc toothed V band of flexural stress is little, tensility good, wear-resisting property is high, easy to use joint group are provided.

The utility model is to constitute like this: it comprises belt body I, this belt body I is intertwined and connected by upholding glue-line (1), cotton rope that layer (2), a cushion gum layer (3), cotton rope twine strength layer (4), orientated short fiber compression glue-line (5) is formed, the V-type sectional shape a that is shaped as 2～8 parallel connections of the transversal section bottom of belt body I, longitudinal axis O direction at the top of V-type sectional shape a along belt body I has continuous arc toothed b, and the upper surface c of belt body I is a flat surface.

The utility model is compared with existing driving belt, the utlity model has length and controls unanimity, flexural stress is little, tensility good, wear-resisting property is high, easy to use advantage easily.Owing to adopted technique scheme, the utlity model has following characteristics:

1, tie layer can make each single V band non-consistently vibrates formation and disappears mutually and cut to bone, and give each root with lateral stiffness and stability by the structural type of joint group, thereby eliminate the oscillation phenomenon of each root, therefore the utility model is difficult for producing shake in use, bounce and turn over band, tie layer processing cotton rope canoe, make the good stability of interband level, be difficult for falling band in the running and do not interfere with each other, it is applicable to pulsating load and impact is arranged, the occasion of vibration, be specially adapted to the driving of parallel axes of vertical ground, more can adapt to the joint group infantees band tie layer that causes greatly because of belt wheel race centre distance error and tear phenomenon;

2, owing to evenly distribute arc toothedly in transmission belt body of the present utility model compression glue-line circumferential section direction, its flexural stress is diminished, frictional contact surface is effective, and frictional force is big, and transmission power is big, and usefulness is good, and it is little to generate heat, good heat dissipation, and it is good that song is disturbed performance;

3, owing to mix orientated short fiber at compression glue-line of the present utility model, strengthened the belt body lateral stiffness, made V be with on-stream its cross section to reduce recessed bent distortion, the rope stamen is stressed evenly, improve V band ability to bear, make the compression glue-line wear-resisting effective, frictional force increases, and transmission is effective, because tie layer is to adopt the cotton rope canoe, it can play interconnect function, strengthens the tensile strength of strength layer, therefore belt body tensile strength is increased.

Accompanying drawing 1 is a structural representation of the present utility model.

Embodiment of the present utility model: when making the utility model, its sulfuration process and equipment preferably adopt the manufacturing equipment of twin drum steel band pressurization electrical heating continuous sulfuration, and to make a drum be profile of tooth heating press vulcanization drum, another drum is roll adjustment fixed length support drum, during making, belt body I is made into by upholding glue-line (1), cotton rope be intertwined and connected the layer (2), cushion gum layer (3), cotton rope twines strength layer (4), the five-layer structure belt body that orientated short fiber compression glue-line (5) is formed, and the shape of the transversal section bottom of belt body I is made as the V-type sectional shape a of 2～8 parallel connections, continuous arc toothed b is produced along the longitudinal axis O direction of belt body I in top at V-type sectional shape a, and the upper surface c of belt body I is made as flat surface.

Claims

1, the arc toothed V band of a kind of joint group, it comprises belt body I, it is characterized in that: belt body I is intertwined and connected by upholding glue-line (1), cotton rope that layer (2), a cushion gum layer (3), cotton rope twine strength layer (4), orientated short fiber compression glue-line (5) is formed, the V-type sectional shape a that is shaped as 2～8 parallel connections of the transversal section bottom of belt body I, longitudinal axis O direction at the top of V-type sectional shape a along belt body I has continuous arc toothed b, and the upper surface c of belt body I is a flat surface.
