Description
Technical field
The utility model relates to a kind of engaging and disengaging gear, particularly a kind of unidirectional transmission clutch.
Background technique
At present, unidirectional transmission clutch correlation technique is very ripe, is widely used in the occasion of various requirement unidirectional delivery power or moment, can carry out highi degree of accuracy and transduction activity expeditiously.But its structure is generally complicated, and manufacture cost is higher.And at some transmission accuracy to be required be not very high occasion, owing to require differently, and wishes more to need a kind of reliable and simple, cheap unidirectional transmission clutch on the Transmitted chains of for example a lot of farm machinery of reducing production costs as far as possible.
The model utility content
The purpose of this utility model is, a kind of unidirectional transmission clutch simple in structure is provided.Being used for the transmission accuracy requirement is not very high occasion, both can bonding to the reliability requirement of transmission, also can significantly reduce production costs.
The technical solution of the utility model.A kind of unidirectional transmission clutch.Comprise wheel shaft, wheel shaft is provided with driving wheel, and driving wheel is provided with ratchet; Also be provided with follower on the wheel shaft, follower is provided with ratchet, and ratchet is connected with ratchet on the driving wheel.
In the above-mentioned unidirectional transmission clutch, described driving wheel and follower are rotationally connected through bearing with wheel shaft.
In the aforesaid unidirectional transmission clutch, described ratchet is located by connecting through screw and driving wheel.
In the aforesaid unidirectional transmission clutch, described follower two or more ratchets that are uniformly distributed along the circumference.
In the aforesaid unidirectional transmission clutch, described ratchet is rotationally connected through screw and follower, and ratchet is provided with the spring that is connected with follower.
In the aforesaid unidirectional transmission clutch, described driving wheel and follower endoporus are provided with the hole circlip groove, and the hole is with being provided with the hole back-up ring in the circlip groove; Wheel shaft is provided with the shaft block ring groove, is provided with shaft block ring in the shaft block ring groove.
Compared with prior art, the utility model is owing to adopted simple ratchet, the unidirectional drive mechanism of ratchet, being used for the transmission accuracy requirement is not very high occasion, both can bonding to the reliability requirement of transmission, can in the middle of rugged environment, move, and have Installation and Debugging and regular maintenance convenience, also can significantly reduce production costs and the regular maintenance cost, durable in use, long working life.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Being labeled as in the accompanying drawing: 1 wheel shaft, 2 driving wheels, 3 ratchets, 4 followers, 5 ratchets, 6 bearings, 7 screws, 8 springs, 9 circlip grooves, 10 holes back-up ring 11 shaft block ring grooves 12 shaft block rings
Embodiment
The utility model is described in further detail below in conjunction with embodiment, but not as to restriction of the present utility model.
Embodiment of the present utility model.A kind of unidirectional transmission clutch, as depicted in figs. 1 and 2.Comprise wheel shaft 1, wheel shaft 1 is provided with driving wheel 2, and driving wheel 2 is provided with ratchet 3; Also be provided with follower 4 on the wheel shaft 1, follower 4 is provided with ratchet 5, and ratchet 5 is connected with ratchet 3 on the driving wheel 2.Described driving wheel 2 and follower 4 are rotationally connected through bearing 6 with wheel shaft 1, and bearing 6 adopts deep groove ball bearing.Described ratchet 3 is located by connecting through screw 7 and driving wheel 2.Described follower 4 four ratchets 5 that are uniformly distributed along the circumference.Described ratchet 5 is rotationally connected through screw 7 and follower 4, and ratchet 5 is provided with the spring 8 that is connected with follower 4.Described driving wheel 2 and follower 4 endoporus are provided with hole circlip groove 9, and the hole is with being provided with hole back-up ring 10 in the circlip groove 9; Wheel shaft 1 is provided with shaft block ring groove 11, is provided with shaft block ring 12 in the shaft block ring groove 11.The location that is used for bearing 6.
Working procedure of the present utility model and principle
As shown in Figure 2, it comprises follower 4, four ratchets 5 evenly distribute on follower 4, ratchet 5 can rotate and pass through spring 8 respectively and be connected with follower 4 around its set screw 7, ratchet 3 tooth root inboards are withstood on ratchet 5 tops respectively, ratchet 3 is connected with driving wheel (Fig. 2 does not draw) by set screw 7, and the ratchet 3 on the driving wheel is installed on the same wheel shaft 1 by deep groove ball bearing 6 respectively with follower 4.During use, wheel shaft 1 two ends are fixed, and when driving wheel 1 direction of arrow when running in Fig. 2, head on ratchet 3 by ratchet 5 and drive followers 4 and turn round along same direction; When driving wheel 1 when arrow shown in Figure 2 turns round in the other direction, the gear teeth outer side surface of ratchet 3 outwards ejects ratchet 5 tops, do not carry out the transmission of power, simultaneously, ratchet 5 slips over behind the gear teeth peak of ratchet 3 under the effect of spring 8 return rapidly, prepares for the power transmission that may carry out next time at any time.
