Abstract
An overrunning clutch with flexible arms belongs to the field of machinery and is characterized in that the overrunning clutch comprises an outer ring (1) and an inner ring (5), a through hole (2) for fixing the outer ring onto needed mechanical equipment is arranged on the outer ring (1), a plurality of flexible arms (4) are evenly distributed along the tangential direction of an outer circle of the inner ring (5), the end of each flexible arm (4) is connected with a diamond block (3), an obtuse angle of the diamond block (3) is connected with the flexible arms (4), and two adjacent edges forming an acute angle of the diamond block (3) are connected by means of arc transition. The overrunning clutch aims to overcome the shortcoming that a traditional overrunning clutch has numerous parts and is difficult in assembly and maintenance and unfavorable for microminiaturization. The overrunning clutch comprising only two parts can be applied to microminiature machinery, and transfers movement and small power, wherein the parts are suitably made of nylon or engineering plastics by means of injection molding.
Description
Technical field
The present invention relates to a kind of free wheel device, belong to mechanical field.
Background technique:
Free wheel device is a kind of mechanical device that satisfies unidirectional delivery motion and power, is widely used in the machinery such as bicycle, lathe, impulse stepless gear box.Tradition free wheel device part is more, and structure is complicated, is unfavorable for the use of microminiature machinery.
Summary of the invention:
The objective of the invention is to: it is many to overcome traditional free wheel device part, installation and maintenance difficulty is unfavorable for the shortcoming of microminaturization, designs a kind of and is made up of two parts, can be applied to microminiature machinery, the free wheel device of transmitting movement and low-power.Its part is suitable for processing through injection moulding with nylon or engineering plastics.
Fig. 1 is the erection drawing of this kind clutch.It is characterized in that: this kind free wheel device has 2 parts to be formed, and is respectively outer ring 1 and inner ring 5 shown in Figure 3 shown in Figure 2; Through hole 2 is arranged on the outer ring 1, be used for fixing on required machinery; Tangent direction along the cylindrical of inner ring 5 is uniformly distributed with several submissive arms 4; The end of submissive arm 4 connects a diamond block 3; The obtuse angle and the submissive arm 4 of diamond block 3 link, and the adjacent two edges that diamond block 3 forms acute angles links to each other with arc transition.
The working principle of the submissive arm free wheel device that the present invention proposes is narrated as follows:
The inner ring of submissive arm free wheel device uses elastic material to process, and submissive arm 4 is a rectilinear form before assembling.After assembling with outer ring 1, bending has taken place in submissive arm 4, and the crooked elastic force that produces is stuck between inner ring 5 and the outer ring 1 diamond block 3, and is as shown in Figure 1.In position shown in Figure 1, when outer ring 1 is a driving link, when rotating counterclockwise, because the frictional force of the 1 pair of diamond block 3 in outer ring is opposite with the elastic force of 4 pairs of diamond blocks 3 of submissive arm, diamond block 3 can not be stuck with outer ring 1 and inner ring 5, so inner ring 5 is with outer ring 1 rotation.When outer ring 1 clockwise rotates, identical to the elastic reaction direction of 4 pairs of diamond blocks 3 of frictional force and submissive arm of diamond block 3, the clockwise direction minor rotation will take place in diamond block 3, and inner ring 5 and outer ring 1 is stuck, moved simultaneously in inner ring 5 and outer ring 1.In like manner, when inner ring 5 was driving link, if inner ring 5 clockwise rotates, did not rotate with inner ring outer ring 1, and when inner ring 5 rotated counterclockwise, rotated with inner ring 5 outer ring 1, thereby accomplish the function of free wheel device.
Description of drawings
The submissive arm free wheel device of Fig. 1 erection drawing.
The submissive arm free wheel device of Fig. 2 outer ring parts drawing.
The submissive arm free wheel device of Fig. 3 inner ring parts drawing.
Embodiment
Embodiment of the present invention such as Fig. 1-shown in Figure 3.In experiment, use nylon to be material.The outer ring external diameter is 20mm, and the outer ring internal diameter is 14mm, and the external diameter of inner ring is 7mm, and internal diameter is 4mm.Submissive arm thickness 0.6mm, diamond block length of side 2mm, acute angle are 45 °, the knuckle radius is 0.4mm.Can transmit 16Nm moment in the experiment.
Claims (1)
