Abstract

The invention discloses a novel rubber sleeve, which belongs to the machinery technical field, and comprises a hollow circular tube-shaped rubber formed by the rubber sleeve, the through holes with complex number are provided between the internal diameter and the external diameter, the through holes are uniformly distributed at the circumference of a circular tube, the inner side accommodate space is sleeved inside machinery equipment, the inner side accommodate space of the rubber sleeve is passed through axle center of the machinery equipment, the outer side of the rubber sleeve is passed through a cold rolling sheet, an outer expansion structure at the axle center of the machinery equipment enlarge the rubber sleeve to reach a state of no sliding while clamping with the cold rolling sheet; the stress expansion of the rubber sleeve is the stretching expansion analogous with expansion with heat and contraction with cold, the shape of the through hole can be a triangular form, a semicircle form and a star form, the novel rubber sleeve has great progress and practicality, and the cold rolling sheet is not influenced by the non-flattening surface due to expansion force.

Description

A kind of new type rubber sleeve

Technical field

The invention discloses a kind of new type rubber sleeve, belong to field of mechanical technique.

Background technology

Existing rubber bush technology, because suitable large of the required ton force of expansionary force of the large rubber bush of support, in order to use less strength can support large rubber bush, namely carve thin cut such as V-type indentation or U-shaped indentation on the rubber bush surface, so reduce the required tension force of the large rubber bush of support, supportted large tension force and be out of shape yet the surface of delineation namely affects cold rolling roll bending.

Summary of the invention

In order to address the above problem, the invention provides a kind of new type rubber sleeve.

In order to achieve the above object, the invention provides following technical scheme: a kind of new type rubber sleeve, comprise the hollow round tubular rubber that rubber bush consists of, between internal diameter and external diameter distance, be provided with plural through hole, through hole is evenly distributed in the circumference of pipe; Inboard accommodation space is namely with being sheathed on machinery equipment, the inboard accommodation space of rubber bush is arranged in the place, axle center of machinery equipment, the rubber bush outside wears cold rolling roll bending, use again the structure that extends out at the place, axle center of machinery equipment that rubber bush is supportted greatly, reach with cold rolling roll bending and reach the non-slip state that clamps; The stressed expansion of rubber bush is that similar pattern of expanding with heat and contract with cold is done spreading, and through hole can be triangular form, semi-circular, star-like etc., furnishes quantity and size in circumference according to the project power requirements set.

The invention has the beneficial effects as follows: have splendid progressive and practicality, the non-smooth surface because of expansionary force does not affect cold rolling roll bending.

Description of drawings

Fig. 1 is front view of the present invention

Fig. 2 is three-dimensional exploded view of the present invention

Fig. 3 is enforcement example figure of the present invention

Among the figure: 1, rubber bush, 11, through hole, 2, inboard accommodation space, 3, machinery equipment, 31, the place, axle center, 311, extend out structure 4, cold rolling roll bending,

The specific embodiment

The invention will be further described below in conjunction with accompanying drawing.

Such as Fig. 1, Fig. 2 and shown in Figure 3, a kind of new type rubber sleeve comprises the hollow round tubular rubber that rubber bush 1 consists of, and is provided with plural through hole 11 between internal diameter and external diameter distance, and through hole 11 is evenly distributed in the circumference of pipe; Inboard accommodation space 2 is namely with being sheathed on machinery equipment, the inboard accommodation space 2 of rubber bush 1 is arranged in the place, axle center 31 of machinery equipment 3, rubber bush 1 outside wears cold rolling roll bending 4, use again the structure 311 that extends out at the place, axle center 31 of machinery equipment 3 to support rubber bush 1 large, reach with cold rolling roll bending 4 and reach the non-slip state of clamping, namely use this state to reach the rewinding coil of wire and become cold rolling roll bending 4 or solution spiral to use cold rolling roll bending 4 in the automated production of continuous processing; The stressed expansion of rubber bush 1 is that similar pattern of expanding with heat and contract with cold is done spreading, and through hole 11 can be triangular form, semi-circular, star-like etc., furnishes quantity and size in circumference according to the project power requirements set.

The stressed expansion of rubber bush 1 is that similar pattern of expanding with heat and contract with cold is done spreading, so reduce rubber bush 1 surfaces externally and internally after the through hole 11 of demand expansionary force does not affect expansion; So, reach the height driving fit with plant equipment 3 and cold rolling roll bending 4, reaching is difficult for skidding does not also affect the effect on cold rolling roll bending 4 surfaces because of expansionary force.

Claims

1. a new type rubber sleeve comprises the hollow round tubular rubber that rubber bush (1) consists of, and it is characterized in that, is provided with plural through hole (11) between internal diameter and external diameter distance, and through hole (11) is evenly distributed in the circumference of pipe; Inboard accommodation space (2) is namely with being sheathed on machinery equipment, the inboard accommodation space (2) of rubber bush (1) is arranged in the place, axle center (31) of machinery equipment (3), rubber bush (1) outside wears cold rolling roll bending (4), use again the structure (311) that extends out at the place, axle center (31) of machinery equipment (3) that rubber bush (1) is supportted greatly, reach with cold rolling roll bending (4) and reach the non-slip state that clamps; The stressed expansion of rubber bush (1) is that similar pattern of expanding with heat and contract with cold is done spreading.

2. a kind of new type rubber sleeve according to claim 1 is characterized in that, described through hole (11) can be triangular form, semi-circular, star-like etc., furnishes quantity and size in circumference according to the project power requirements set.
