Abstract

The utility model discloses an overrun clutch with a combined spring-shaped cavity. A roller (2) is positioned in a roller groove (1a) of a body (1), wherein one end surface of the body (1) is covered by a housing (4); a baffle plate (5) is arranged at the other end surface of the body (1); a rectangular groove (1b) communicated with the roller groove (1a) is arranged beside the roller groove (1a) of the body (1); a rectangular spring (3) is arranged in the rectangular groove (1b); the rectangular groove (1b) is positioned at a notch on the internal circumferential surface of the body (1) and stopped by an edgefold (6); a rectangular cavity communicated with the roller groove (1a) is surrounded by the edgefold (6) is fixed on the housing (4); and the edgefold (6), the housing (4), the baffle plate (5) and the wall of the rectangular groove (1b). The overrun clutch disclosed by the utility model has the advantages of low requirement on manufacturing precision and assembling precision, a simple and compact structure, working reliability, high bearing capacity, long service life, good manufacturability and low processing cost; and the housing and the body are reliably combined so that circumferential loosening is not caused.

Description

The free wheel device in cluster spring shape chamber

Technical field

The utility model relates to a kind of free wheel device, and relating in particular to a kind of shape chamber of placing spring is the free wheel device in combined type shape chamber.

Background technique

Free wheel device is made up of body, roller, case, spring and catch etc., and roller is positioned at the roller slot of body, and the cell wall of a side has the spring of packing in the roller slot.End face of this body is covered by case, and another end face of this body is provided with catch.This kind structure need be processed roller slot adding man-hour, then in the cell wall punching, process cumbersome, the structure relative complex.And when assembling, roller, spring are installed cumbersome, the particularly installation of spring.Simultaneously also be for spring easy for installation, can not be very compact between the hole of roller slot cell wall and the spring, reliability is relatively poor in the clutch work, noise is big, bearing capacity is relatively poor.

The model utility content

Technical problem to be solved in the utility model is to provide a kind of free wheel device of cluster spring shape chamber of simple in structure, reliable operation.

The technical solution of the utility model is as follows: the free wheel device in a kind of cluster spring shape chamber, comprise body, roller, case, catch, wherein said roller is positioned at the roller slot of body, end face of this body is covered by case, another end face of this body is provided with catch, its key is: the roller slot next door of described body has the rectangle groove that is communicated with it, be placed with the rectangle spring in this rectangle groove, the notch that this rectangle groove is positioned at the body inner peripheral surface is blocked by flanging, this flanging is fixed on the case, described flanging, case, catch and rectangle groove cell wall surround a rectangle shape chamber that communicates with roller slot.Earlier the rectangle spring is packed into during assembling in the rectangle groove, flanging flange again surrounds the shape chamber of rectangle together, assemble more convenient, and also rectangle shape chamber compactness more of spring.

Above-mentioned flanging and case are the integrative-structure that punching press forms, and this flanging is again to in-flanges.So process simple more and method, easy processing, processing cost is lower.

Beneficial effect: accuracy of manufacturing of the present utility model and assembly precision require low; Mechanism is simple, compactness, and reliable operation, bearing capacity is big, and the life-span is long; Anufacturability is good, and processing cost is low; Case combines with body reliably, no circumferencial direction loosening.

Description of drawings

Fig. 2 is the A-A sectional view of Fig. 1.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

As Fig. 1, shown in Figure 2, the free wheel device in a kind of cluster spring shape chamber, by body 1, roller 2, rectangle spring 3, compositions such as case 4 and catch 5, wherein said roller 2 is positioned at the roller slot 1a of

body

1,1 one end faces of this body are covered by case 4, this body 1 another end face is provided with catch 5, the roller slot 1a next door of described body 1 has the rectangle groove 1b that is communicated with it, be placed with rectangle spring 3 in this rectangle groove 1b, the notch that this rectangle groove 1b is positioned at body 1 inner peripheral surface is blocked by flanging 6, this flanging 6 is fixed on the case 4, flanging 6 and the integrative-structure of case 4 for punching press formation, and this flanging 6 is again to in-flanges.Described flanging 6, case 4, catch 5 and rectangle groove 1b cell wall surround a rectangle shape chamber that communicates with roller slot 1a.Rectangle spring 3 one ends are against rectangle groove 1b cell wall, and rectangle spring 3 the other ends are against on the roller 2.

Although below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic rather than determinate; those of ordinary skill in the art is under enlightenment of the present utility model; under the prerequisite of the utility model aim and claim; can make multiple similar expression, such conversion all falls within the protection domain of the present utility model.

Claims

1. the free wheel device in a cluster spring shape chamber, comprise body (1), roller (2), case (4), catch (5), wherein said roller (2) is positioned at the roller slot (1a) of body (1), (1) end face of this body is covered by case (4), another end face of this body (1) is provided with catch (5), it is characterized in that: roller slot (1a) next door of described body (1) has the rectangle groove (1b) that is communicated with it, be placed with rectangle spring (3) in this rectangle groove (1b), the notch that this rectangle groove (1b) is positioned at body (1) inner peripheral surface is blocked by flanging (6), this flanging (6) is fixed on the case (4), described flanging (6), case (4), catch (5) and rectangle groove (1b) cell wall surround a rectangle shape chamber that communicates with roller slot (1a).
