Detailed Description
The invention will be further described in detail with reference to the following examples, which are given in the accompanying drawings.
As shown with reference to figures 1-5,
a one-way bearing of bicycle, including stopping the outer race 1, inner race 2; the side surface of the inner ring 2 is provided with an L-shaped cutting groove 3, a spring 4 and a cylindrical roller 5 are arranged in the cutting groove, the spring 4 is used for providing elastic force for the cylindrical roller 5 to attach to the locking outer ring 1, when the cylindrical roller 5 is attached between the L-shaped cutting groove 3 and the locking outer ring 1, the inner ring 2 rotates in the forward direction and forms clamping fit with the locking outer ring 1 through the cylindrical roller 5 so as to drive the outer ring to rotate; when the inner ring 2 rotates reversely, the cylindrical roller 5 is separated from the locking outer ring 1;
the two ends of the locking outer ring 1 are further provided with a front cover plate 6 and a rear cover plate 7, the front cover plate 6 and the rear cover plate 7 are fixedly connected to the two sides of the inner ring 2 through bolts 8, and the front cover plate 6 and the rear cover plate 7 are respectively attached to the two sides of the locking outer ring 1.
Wherein locking outer lane 1 cooperates through cylindrical roller 5 with inner circle 2, utilizes the thrust that the elasticity of spring 4 produced, blocks cylindrical roller 5 between L type grooving 3 and locking outer lane 1, and when rotating inner circle 2, can drive locking outer lane 1 through cylindrical roller 5 and rotate this moment. And when the inner circle 2 counter-rotation, cylindrical roller 5 just can't block between rotation outer lane and inner circle 2, specifically refer to the attached drawing, the structure of L type grooving 3 is the wedge, and when inner circle 2 assembled in locking outer lane 1, L type grooving 3 had the main aspects to dwindle to the tip, and the tip can cooperate cylindrical roller 5 to block, and then lets inner circle 2 drive locking outer lane 1 and rotate, otherwise, the rotation direction is opposite then can't block, realizes unidirectional separation and reunion rotation this moment. Compared with the ratchet mechanism adopted in the prior art, the sound of 'Da' can not appear, and the noise is greatly reduced.
In addition, the front cover plate 6 and the rear cover plate 7 are arranged, the dustproof effect can be improved, the inner ring 2 is pre-installed through the installation of the front cover plate and the rear cover plate 7, the inner ring 2, the cylindrical roller 5 and the spring 4 can be prevented from dropping through the laminating effect of the front cover plate 6 and the rear cover plate 7 on the locking outer ring 1, the assembling effect is improved, the pre-installation effect is improved, and the follow-up assembly is facilitated.
The design of front shroud 6 and back shroud 7 is not through improving dustproof effect, can also increase the preinstallation effect, can avoid moreover that inner circle 2 breaks away from with locking outer lane 1 in the use, in addition, because front shroud 6 and back shroud 7 are in fact with inner circle 2 fixed connection, consequently can rotate along with inner circle 2 rotates, when inner circle 2 rotates, can also throw away the dust on front shroud 6 and the back shroud 7 and fall.
In order to increase the stability of the spring 4, the assembly state change cannot occur in the L-shaped cutting groove 3, a threaded hole 31 is formed in one side groove wall of the L-shaped cutting groove 3, one end of the spring 4 is matched with the threaded hole 31 to be in threaded connection in the threaded hole 31, and the other end of the spring is abutted against the cylindrical roller 5.
Utilize the screw thread of screw hole 31 and spring 4 to cooperate, can realize threaded connection with the help of the characteristic of spring 4, on the one hand easy to assemble, on the other hand can improve installation stability.
The stop outer ring 1 is in a butterfly shape and provided with a recess 11 matched with the inner ring 2 in shape; the inner ring 2 is located in the recess 11 of the locking outer ring 1.
The stop outer ring 1 can improve the axial impact strength by designing the form of the recess 11, and meanwhile, the inner ring 2 can be wrapped in the recess 11, so that the reliability of the structure is improved.
The position of the recess 11 of the stop outer ring 1 corresponding to the position of the inner ring 2 is provided with an annular step 12 extending along the circumferential direction of the recess 11, and the recess 11 forms a fitting part which is assembled with the inner ring 2 through the step 12; the front cover plate 6 and the rear cover plate 7 are respectively attached to two sides of the assembly portion.
The annular step 12 can form a position for attaching the front cover plate and the rear cover plate 7, and the thickness of the recess 11 is increased due to the step 12, so that the strength of the position where the locking outer ring 1 is matched with the cylindrical roller 5 can be improved, and the service life of the whole body is prolonged. And because the front and rear cover plates 7 have good binding surfaces, the dustproof effect can be improved, and the sealing effect is further improved.
In addition, the side of the front cover plate 6 or the rear cover plate 7 is provided with a speed measuring device which is meshed and linked with the front cover plate 6 or the rear cover plate 7, the speed measuring device comprises a rotary disc 91 meshed and linked with the front cover plate 6 or the rear cover plate 7 and a Hall detector 92 matched with the rotary disc 91, and a plurality of through holes 93 are formed in the position, corresponding to the Hall detector 92, on the rotary disc 91 along the circumferential direction.
Generally, current speed sensor can set up with the help of than great carousel 91, it is also difficult to direct reduce carousel 91 generally, tooth and carousel 91 through on front shroud 6 or the back shroud 7 mesh in this scheme, because carousel 91 kneads the transmission, can be real at this moment carry out the rotational speed transmission with the transmission effect when front shroud 6 or back shroud 7 rotate, then detect through carousel 91 to the size is less, conveniently reduce the weight of bicycle and relevant part volume, increase aesthetic measure.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
