The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.
Fig. 1 is a schematic block diagram of one state of a transmission assembly 100 of a transmission according to one embodiment of the present invention, fig. 2 is a schematic block diagram of another state of the transmission assembly 100 of the transmission according to one embodiment of the present invention, fig. 3 is a schematic sectional view of a portion a of the transmission assembly shown in fig. 1, and fig. 4 is a schematic sectional view of a portion B of the transmission assembly shown in fig. 2. As shown in fig. 1, 2, 3 and 4, in a specific embodiment, a transmission assembly 100 of the transmission includes an output shaft 10, a sleeve 20 and a clamp spring 30, an outer wall of the output shaft 10 is provided with a first groove 11 arranged along a circumferential direction of the output shaft, the first groove 11 includes a first portion 111 and a second portion 112, a recessed depth of the first portion 111 is smaller than that of the second portion 112, and the first portion 111 is close to an end of the output shaft 10. The shaft sleeve 20 is sleeved on the output shaft 10, and a second groove 21 arranged opposite to the first groove 11 is formed on the inner wall of the shaft sleeve 20. The circlip 30 is installed between the second portion 112 and the second groove 21, and the circlip 30 is configured to move from the second portion 112 to the first portion 111 under the rotation of the output shaft 10 and the driving of the axial movement of the sleeve 20, so as to be clamped between the first portion 111 and the second groove 21 to limit the axial movement of the sleeve 20. Here, dividing the first groove 11 into the first portion 111 and the second portion 112 corresponds to providing the bottom of the first groove 11 in a stepped shape. The sleeve 20 is provided with a side wall which is inclined and which is decomposed by a force in the axial direction when the radial force is applied.
This embodiment is equivalent to the first recess 11 being stepped, and when the sleeve 20 is mounted on the output shaft 10, the second recess 21 of the sleeve 20 is arranged opposite to the second portion 112 of the first recess 11 of the output shaft 10, and the circlip 30 is located between the second portion 112 and the second recess 21 and is in a free state, see fig. 3. When the output shaft 10 of the transmission rotates, the shaft sleeve 20 is subjected to an outward releasing force, the shaft sleeve 20 carries the snap spring 30 to move leftward, and the snap spring 30 moves from the second portion 112 to the first portion 111, which is equivalent to moving to a step, as shown in fig. 4. When the sleeve 20 rotates to bring the snap spring 30 to try to be tightly held and compressed, the first portion 111 inhibits the snap spring 30 from being compressed, thereby ensuring that the sleeve 20 cannot be disengaged from the output shaft 10.
In this embodiment, the width of the second groove 21 is larger than the diameter of the circlip 30 and smaller than the width of the first groove 11. That is, the width of the second groove 21 is sufficient to ensure that the circlip 30 cannot fall off from the first portion 111 to the second portion 112 when moved to a position opposite to the first portion 111 of the first groove 11.
In this embodiment, the second groove 21 includes a first side wall 211 and a second side wall 212 which are oppositely arranged, the second groove 21 further includes a first bottom 213, and the joint of the first bottom 213 and the first side wall 211 and the joint of the second bottom 213 and the second side wall 212 are respectively provided with an arc-shaped chamfer, so that burrs in the machining process can be removed, and the appearance can be ensured.
Further, the second portion 112 comprises a third sidewall 114 and a fourth sidewall 113 arranged oppositely, wherein the height of the third sidewall 114 is smaller than the height of the fourth sidewall 113. The second portion 112 further includes a second bottom portion 115, and a joint between the second bottom portion 115 and the third side wall 114 and a joint between the second bottom portion 115 and the fourth side wall 113 are respectively provided with an arc-shaped chamfer, so that burrs in a machining process can be removed, and the appearance can be ensured.
Further, the first portion 111 comprises a fifth sidewall 116 and a third bottom 117, wherein the fifth sidewall 116 is arranged opposite to the fourth sidewall 113, and the third bottom 117 is arranged in parallel with the second bottom 115 and connected to the third sidewall 114. Here, the third bottom 117, the third sidewall 114, and the second bottom 115 are formed in a step shape.
In this embodiment, the junction of the fifth sidewall 116 and the third bottom 117 is provided with an arc-shaped chamfer. The junction of the third bottom 117 and the third side wall 114 is provided with an arc-shaped chamfer, so that burrs in the processing process can be removed, and the appearance can be ensured.
Further, the distance between the first sidewall 211 and the second sidewall 212 is smaller than the distance between the third sidewall 114 and the fourth sidewall 113. The distance between the first sidewall 211 and the second sidewall 212 is greater than the distance between the fifth sidewall 116 and the third sidewall 114. That is, the width of the first bottom 213 is smaller than the width of the second bottom 115. The width of the first bottom 213 is greater than the width of the third bottom 117.
The utility model also provides a speed changer which is provided with the transmission assembly 100. The transmission assembly 100 need not be described in detail herein.
This embodiment can be engaged between the first portion 111 and the second recess 21 when the circlip 30 moves to the first portion 111 by setting the recess on the output shaft 10 of the conventional transmission to be a stepped recess, so as to limit the axial movement of the sleeve 20 and prevent the sleeve 20 from being removed from the output shaft 10 of the transmission.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the utility model may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the utility model.
