Detailed Description
In order that the present invention may be more clearly understood, the following detailed description is given with reference to the accompanying drawings.
Example 1:
referring to fig. 1 to 3, the present embodiment provides a driving apparatus, including: the worm gear comprises a box body 1, a worm gear body arranged in the box body 1, a screw rod 5 which is connected with the worm gear body and is suitable for one end to be inserted into the box body 1, and a worm 6 which is suitable for being inserted into the box body 1 and is used for meshing with the worm gear body; wherein the worm 6 is connected with a motor 7 for driving the worm 6 to rotate.
Roughly speaking, first, a worm wheel body including a shaft portion 21 and a tooth portion 22 formed on a circumferential side wall of the shaft portion 21; the shaft part 21 is sleeved with an elastic component; the elastic assembly comprises at least one elastic pad 31 and at least one flat pad 32; the elastic component is sleeved on the shaft part 21 and axially limited between the tooth part 22 and the inner wall of the box body 1.
It should be noted that, when the driving device is not in use, that is, when the elastic pad 31 is not deformed under pressure, there is an axial distance between the end surface of the shaft 21 where the elastic component is sleeved and the inner wall of the case 1, and the axial distance is smaller than the maximum axial compression amount of the elastic pad 31. Under such structure, the axle head face that the position that the cover was equipped with elastic component on the axial region 21 can be earlier with the inner wall butt of box 1 before elastic gasket 31 pressurized to maximum deformation to make the elastic gasket 31 the biggest deformation condition can not appear in the use, make the atress and the deflection of elastic gasket 31 be in controllable within range, prevent that elastic gasket 31 from appearing tired so that irreversible deformation appears because of warping too big, then lose its elastic force and finally produce the condition that the elasticity became invalid. Therefore, the driving device of the embodiment can be effectively ensured to be kept in a long-term and stable use state, and the service life of the whole driving device is prolonged.
It should be noted that, while the driving device in the present embodiment is not in use, the elastic pad 31 in the elastic assembly is in an uncompressed state, for example, when the driving device is not in use, the elastic pad 31 in the elastic assembly is in a compressed and slightly deformed state, and for this state, the axial distance between the shaft end surface of the portion of the shaft portion 21 where the elastic assembly is sleeved and the inner wall of the case 1 is smaller than the maximum axial compression amount of the elastic pad 31 minus the amount of the elastic pad 31 that has been compressed and deformed in the initial state. That is, the use requirement of the present embodiment is satisfied as long as the shaft end surface of the portion of the shaft portion 21 on which the elastic component is sleeved can be abutted with the inner wall of the case 1 before the elastic gasket 31 is pressed to the maximum deformation.
More specifically, the worm wheel body is adapted to move within the housing 1 so that the axial end surface of the portion of the shaft portion 21 where the elastic member is fitted abuts against the inner wall of the housing 1. When the worm wheel body moves in the box 1, the tooth portion 22 on the worm wheel body pushes the elastic component, so that the elastic gasket 31 in the elastic component generates compression deformation, and the elastic gasket 31 has the largest compression deformation amount, generally speaking, the largest compression deformation amount is the deformation amount corresponding to the state from the free state to the completely flattened state.
In addition to the above-mentioned structure, it should be noted that, since the entire elastic component is fitted over the portion of the shaft portion 21 located at one axial end of the tooth portion 22, in order to allow this portion of the shaft portion 21 to serve as a support for the elastic component, the axial length of the shaft portion 21 located at one axial end of the tooth portion 22 in contact with the elastic component is not less than the thickness of the elastic component, and therefore, for the inner wall of the case 1 adapted to be in contact with the elastic component and the axial end surface of the shaft portion 21, the inner wall of the case 1 in contact with the axial end surface of the shaft portion 21 is recessed relative to the inner wall of the case 1 in contact with the elastic component, and in this case, the axial distance between the axial end surface of the portion of the shaft portion 21 on which the elastic component is fitted and the inner wall of the case 1 can be made to satisfy the distance required by the elastic component within a reasonable deformation range. In this case, the present embodiment may be configured such that an annular gasket 4 is disposed on an end surface of the inner wall of the case 1 abutting against the shaft end surface of the shaft portion 21, and the annular gasket 4 is sleeved on the screw rod 5. Here, the annular gasket 4 can provide friction properties in a state where the shaft portion 21 of the worm wheel body is in contact with and fitted to the inner wall of the case 1. Of course, because of the annular gasket 4 added here, the shaft end surface of the shaft portion 21 needs to be abutted with the annular gasket 4 before the elastic gasket 31 is pressed to the maximum deformation, that is, the axial distance between the shaft end surface of the shaft portion 21 and the inner wall of the case 1 in the front speed of the embodiment needs to be subtracted by the thickness of the annular gasket 4.
Finally, as for the elastic component adopted in the present embodiment, the elastic component in the present embodiment includes a flat gasket 32 sleeved on the shaft portion 21 and abutting against the tooth portion 22, and an elastic gasket 31 interposed between the flat gasket 32 and the inner wall of the box body 1. In addition, the elastic component may also be formed by using more than two flat gaskets 32 to cooperate with one or more elastic gaskets 31, which is not limited in this embodiment.
For the elastic pad 31 and the flat pad 32 adopted in the present embodiment, in order to improve the structural stability of the elastic pad 31 during the elastic deformation process, the outer diameter of the elastic pad 31 of the present embodiment is smaller than the outer diameter of the flat pad 32. This structure allows both axial ends of the elastic pad 31 to receive a supporting force.
In addition, in an alternative implementation case, the outer diameter of the flat gasket 32 adopted in the present embodiment is not smaller than the diameter of the addendum circle of the tooth portion 22, and on the basis of this structure, for the outer diameter of the elastic gasket 31 smaller than the outer diameter of the flat gasket 32, the outer diameter of the elastic gasket 31 may be the same as the diameter of the addendum circle or the outer diameter of the elastic gasket 31 is slightly larger than the diameter of the addendum circle, by such a structural design, the elastic gasket 31 generates a balanced buffer effect on the worm wheel body during the axial movement of the worm wheel body in the box 1.
It is to be noted that the case 1 adopted in the present embodiment includes a main body 12 and a cover 13; the main body 12 has formed therein an assembly cavity for receiving the worm gear body. For reasons of ease of disassembly, the cover 13 and body 12 are adapted to be lockingly engaged by screws 91.
In addition, an insertion hole 700 adapted to insert one end of the lead screw 5 into the mounting cavity after penetrating is opened in the side wall of the main body 12, and the outer diameter of the shaft portion 21 of the worm wheel body is larger than the inner diameter of the insertion hole 700. Compared with the cover plate 13, the present embodiment has the advantages that the insertion hole 700 is formed in the main body 12, and the main body 12 has high overall strength and can bear higher axial force of the screw 5.
On the basis of this structure, the insertion hole 700 is provided in a cavity wall of the assembly cavity adapted to abut against an end face of the shaft of the portion of the shaft portion 21 on which the elastic member is fitted.
