Abstract
The invention relates to an ultra-thin unidirectional ball clutch, belongs to the field of clutches and aims to overcome the defects of complicated structure, larger thickness, more materials consumed, high cost and heavy weight existing in the existing unidirectional clutch. The ultra-thin unidirectional ball clutch comprises an inner ring, an outer ring and balls, wherein the inner ring is arranged in the outer ring; a semicircular groove is formed in the inner circle surface of the outer ring; at least three semi-circular chutes uniformly distributed along the excircle surface are formed on the excircle surface of the inner ring; the balls and springs are installed in the semi-circular chutes, wherein each spring is slightly shorter than each semi-circular chute; and one ends of the springs are propped against the balls, and the other ends of the springs are fixedly arranged on the inner side of an inner ring chute. The ultra-thin unidirectional ball clutch has the advantages of simple structure, thin thickness and stable running.
Description
Technical field
The invention belongs to clutch field, especially relevant with a kind of ultra-thin unidirectional ball clutch.
Background technique
Usually; Overrunning clutch is made up of outer ring, inner ring, roller, spring and the parts such as side plate, screw that are used for fixing Internal and external cycle; There is complex structure in the clutch of this kind structure, thickness is thicker, the consumption material is many, cost is high and the shortcoming of Heavy Weight, so industry expects to have a kind of simple in structure, ultra-thin, in light weight and appearance of overrunning clutch cheaply always.
Summary of the invention
The object of the invention be exactly to overcome complex structure, thickness that existing overrunning clutch exists thicker, consume that material is many, cost is high and the shortcoming of Heavy Weight; A kind of side plate that do not need is provided; And can prevent that ball and spring from dropping, guarantee that each roller can separate and combine effectively, and the even stressed ultra-thin unidirectional ball clutch of ability; For this reason, the present invention adopts following technological scheme.
Ultra-thin unidirectional ball clutch; Comprise inner ring, outer ring and ball, inner ring is arranged in the outer ring, and the inner headed face of outer ring is provided with a semi-circular recesses; It is characterized in that: the periphery of described inner ring is provided with at least 3 along the equally distributed semicircle skewed slot of periphery; The spring that ball and length slightly are shorter than semicircle chute length is installed in described semicircle skewed slot, and spring one end is against ball, and the other end is fixedly installed on the inboard of inner ring skewed slot.
As the further of technique scheme improved and replenish, the present invention also comprises following additional technical feature.
On a side of described inner ring, be provided with and the corresponding circular hole that connects with skewed slot more than 3 of skewed slot, in order to ball and the spring of packing near the skewed slot inboard.
The periphery of described inner ring is provided with 6 makes ball evenly distribute along the equally distributed semicircle skewed slot of periphery, and clutch is stable.
Assembly process of the present invention is: 1, at first the circular hole of inner ring placed in the middle of the outer ring up, and 2, then ball and spring are packed between inner ring and the outer ring through the circular hole on the inner ring, clutch promptly assembles completion.
The present invention can reach following beneficial effect: 1, ball relies on spring to locate automatically, can not drop, so side plate that needs traditionally and screw etc. no longer are essential; Reduced the number of components of clutch significantly, 2, can a plurality of skewed slots and steel ball be set on the inner ring excircle according to requirement to clutch thickness and moment of torsion; 3, this clutch configuration is simple, and the assembling easy processing has been practiced thrift great deal of steel and manufacturing procedure; Meet current energy-saving and cost-reducing and requirements of green environmental protection; 4, owing to there are not fixing devices such as side plate and screw, it is very thin that clutch can be accomplished, even can reach below 2 millimeters.

Embodiment
Be described in detail below in conjunction with the accompanying drawing specific embodiments of the invention.
Like Fig. 1 ~ shown in Figure 6; The present invention includes inner ring 2, outer ring 1 and ball 3, inner ring 2 is arranged in the outer ring 1, and the inner headed face of outer ring 1 is provided with a semi-circular recesses; The periphery of inner ring 2 is provided with 6 along the equally distributed semicircle skewed slot of periphery; The spring 4 that ball 3 and length slightly are shorter than semicircle chute length is installed in semicircle skewed slot, and spring 4 one ends are against ball, and the other end is fixedly installed on the inboard of inner ring skewed slot; Be provided with and corresponding 6 circular holes 5 that connect with skewed slot of skewed slot near the skewed slot inboard on one side of inner ring 2, in order to ball 3 and the spring 4 of packing into.
Assembly process of the present invention is: 1, at first the circular hole 5 of inner ring 2 placed in the middle of the outer ring 1 up, and 2, then ball 3 and spring 4 are packed between inner ring 2 and the outer ring 1 through the circular hole on the inner ring 25, clutch promptly assembles completion.
