In automotive production, the assembly of the gearbox is complex, and the mounting of the bearings is of great importance in the overall gearbox assembly. In the conventional assembly process of the gearbox, the bearing of the output shaft of the gearbox is usually mounted by means of knocking of a simple tool. However, the strength of the manual rattle in the conventional assembly process of the transmission is large, and the loss of the bearing is easily caused.
In view of this, the present application proposes a gear box production apparatus including a bearing mounting apparatus, and all gear box production apparatuses as far as they include a bearing mounting apparatus belong to the gear box production apparatus as referred to in the present application. Fig. 1 to 4 are schematic views of an embodiment of a bearing mounting device provided in the present application.
Referring to fig. 1 to 3, a bearing mounting device 100 provided in the present application is used for pushing a bearing on an output shaft of a gearbox to a mounting position along an axial direction of the output shaft of the gearbox, and the bearing mounting device 100 includes a mounting member 1, a pushing member 2 and a driving assembly. The mounting piece 1 is sleeved on the output shaft, the mounting piece 1 is provided with external threads 11, and the pushing piece 2 is provided with a matching threaded hole 21 matched with the external threads 11. The driving assembly comprises a driving piece in driving connection with the pushing piece 2, and the driving piece is used for driving the pushing piece 2 to rotate relative to the mounting piece 1 so that the pushing piece 2 can move towards a bearing on the output shaft along the axial direction of the output shaft.
In the technical scheme of this application, through set up external screw thread 11 on installed part 1, set up on pushing away the piece 2 again with external screw thread 11 complex cooperation screw hole 21 to make when the relative installed part 1 rotation of driving piece drive pushing away the piece 2, push away the piece 2 and can follow the axial of output shaft and move towards the epaxial bearing of output. This brings the abutment 2 close to the bearing and pushes the bearing against the mounting position. When the pushing piece 2 moves towards the bearing, the mounting piece 1 cannot move, and after the pushing piece 2 completes the mounting of the bearing, the mounting piece 1 can be detached from the output shaft so as to be used continuously.
Unlike the prior art, the thrust piece 2 is brought close to the bearing by a rotary motion, which makes the thrust exerted by the thrust piece 2 on the bearing more dispersed, without causing wear on the bearing. And the pushing piece 2 can be connected with the driving piece, so that the labor is liberated, the use cost is reduced, and the movement of the pushing piece 2 is more accurate.
In a specific application, the caliber of the thread on the output shaft is arranged in a ladder, so that the mounting piece 1 can be sleeved on the output shaft, but the pushing piece 2 cannot be close to the bearing by being directly screwed with the output shaft. When the pushing member 2 is directly screwed with the output shaft, the pushing member 2 cannot approach the bearing through rotation due to the change of the screw diameter of the output shaft. Therefore, in the present embodiment, the mounting member 1 also actually plays a role of switching the pushing member 2 and the output shaft, so as to avoid the problem of the change of the screw diameter of the output shaft. In practical application, the inner diameter of the pushing piece 2 is larger than the maximum outer diameter of the output shaft, so that the pushing piece 2 can be prevented from contacting with the output shaft in the rotation process, and the pushing piece 2 can be ensured to smoothly rotate.
It should be noted that, in the driving member, there are various embodiments of the driving member, for example, a pneumatic trigger, a stepping motor or a rotary cylinder may drive the pushing member 2 to rotate relative to the mounting member 1, which is not limited herein.
In some embodiments, referring to fig. 2 to 3, the mounting member 1 is provided with a mounting threaded hole 12 extending in the axial direction of the output shaft therethrough, and the mounting member 1 is screwed to the output shaft by means of the mounting threaded hole 12.
In this embodiment, the bearing mounting device 100 needs to be sleeved on the output shaft when in use, and this makes the mounting member 1 need to be detachably mounted on the output shaft, so that the bearing can be detached after the bearing is completely mounted. The use demand of installed part 1 can be satisfied in threaded connection, so in this embodiment, installed part 1 carries out the spiro union with the output shaft through running through the installation screw hole 12 that extends along the axial of output shaft, with the output shaft screw-thread fit fixed when the output shaft is located to installed part 1 cover, when supporting pushing away 2 relative installed part 1 rotation, it can follow the axial activity of output shaft to push away 2 still, can not receive the influence.
In some embodiments, the mounting member 1 is threaded with the output shaft during a particular application, and the mounting member 1 requires constant rotation to complete the installation. The time required to manually rotate the mount 1 is too long, which can affect the machining efficiency. Thus, in an embodiment of the present application, the mounting member 1 includes a main body portion 13 provided with the mounting threaded hole 12 and a first connecting portion 14 disposed at an end of the main body portion 13 remote from the bearing, and the driving assembly further includes a driver drivingly connected to the first connecting portion 14 to drive the mounting member 1 to rotate relative to the output shaft.
In this embodiment, the driver drives the first connecting portion 14 to rotate, and the first connecting portion 14 drives the main body portion 13 to synchronously rotate, so as to realize rotation of the mounting member 1 relative to the output shaft, and thus the mounting member 1 is quickly mounted. The main body portion 13 is connected with the driver through the first connecting portion 14, so that the mounting member 1 can be automatically mounted, and the mounting efficiency is increased. It should be noted that there are many embodiments of the driver, for example, a pneumatic trigger, a stepper motor or a rotary cylinder may drive the first connecting portion 14 to rotate relative to the output shaft, and the specific manner may be selected according to the actual situation, which is not limited herein.
In some embodiments, referring to fig. 3, a side of the first connecting portion 14 facing the main body portion 13 is provided with a first end surface for covering one end of the mounting threaded hole 12, and the first end surface of the first connecting portion 14 is provided with a positioning portion 141 for extending into the mounting threaded hole 12, where the positioning portion 141 is used to abut against the output shaft when the mounting member 1 is located at a preset position.
In a specific application, the position of the mounting member 1 also determines the position of the pushing member 2, so that in order to ensure that the pushing member 2 can push the bearing accurately to the mounting position, the mounting position of the mounting member 1 should also be accurate. In the present embodiment, therefore, the first connecting portion 14 is provided with the positioning portion 141 protruding into the mounting screw hole 12 on the first end surface so as to abut against the output shaft when the output shaft protrudes into the mounting screw hole 12 by a certain length, so that the mounting member 1 cannot be mounted in a further rotation, thus positioning the position of the mounting member 1. Of course, the length of the positioning portion 141 extending into the mounting threaded hole 12 can be adjusted as required, so that the mounting position of the mounting member 1 can be changed, thereby adjusting the movable position of the pushing member 2. The thread caliber on the output shaft is arranged in a gradient, and the positioning part 141 can accurately mount the mounting piece 1 at a required position without being sleeved on an improper thread caliber.
In some embodiments, referring to fig. 2 and 4, the main body 13 is provided with a plurality of first threaded holes 131, the first connecting portion 14 is provided with a plurality of second threaded holes 142 corresponding to the first threaded holes 131 one by one, and the mounting member 1 further includes a plurality of screw members 15 mated with the first threaded holes 131 and the second threaded holes 142, so that the first connecting portion 14 can be screwed and fixed to the main body 13.
In the solution of the present embodiment, the main body 13 needs to be fixedly connected to the first connecting portion 14, and the plurality of screw members 15 respectively pass through the corresponding second threaded holes 142 and extend into the corresponding first threaded holes 131, so that the first connecting portion 14 is screwed and fixed to the main body 13. The screw-connection member 15 can make the torque input by the driver more dispersed by arranging a plurality of screw-connection members, reduce the generation of stress, and the screw-connection mode is more convenient for the replacement and maintenance of the first connection portion 14. In addition, the first connecting portion 14 may be fixedly mounted in a plurality of manners, such as welding, and even the main body portion 13 and the first connecting portion 14 may be directly integrally formed, and not necessarily be fixed by screwing.
In some embodiments, referring to fig. 2 to 3, the bearing mounting device 100 further includes a second connecting portion 22, the second connecting portion 22 is detachably connected to an end of the pushing member 2 away from the bearing, and the driving member is connected to a side of the second connecting portion 22 away from the pushing member 2.
After the mounting member 1 is mounted, the driving member needs to drive the pushing member 2 to rotate, so that the pushing member 2 moves. In the present embodiment, however, the abutment 2 is provided with a mating threaded hole 21, so that the connection of the driving member to the abutment 2 is limited. Therefore, the second connecting portion 22 is detachably mounted at the end of the pushing member 2 away from the bearing, and when the mounting member 1 is mounted, a user can mount the second connecting portion 22 on the pushing member 2, so that the driving member can drive the pushing member 2 to rotate by driving the second connecting portion 22 to rotate. The detachable installation mode of the second connecting part 22 ensures that the second connecting part 22 does not influence the installation of the installation piece 1, and is more convenient to maintain and replace. The pushing member 2 is connected to the driving member through the second connecting portion 22, thereby enabling automatic installation of the pushing member 2. And the pushing member 2 needs to push the bearing to the mounting position, so that the pushing member 2 needs a large force, and therefore the pushing member 2 cannot be rotated by manpower but can only be driven by the driving member. The second connection portion 22 makes the connection of the driving member and the pushing member 2 more convenient and more stable.
In some embodiments, the pushing member 2 is provided with a plurality of insertion holes 23 facing the second connecting portion 22, and the second connecting portion 22 is provided with a plurality of insertion rods 221 corresponding to the insertion holes 23 one by one, and each insertion rod 221 is inserted into the corresponding insertion hole 23.
In this embodiment, when the second connection portion 22 is required to be installed, the user only needs to align the insertion rod 221 with the insertion hole 23 and insert the insertion rod into the corresponding insertion hole 23 to complete the installation. The matching of the inserted link 221 and the insertion hole 23 is simple, the installation is convenient, and the production cost is low.
In some embodiments, an annular mounting groove is provided on the inner sidewall of the mating threaded bore 21, and the annular mounting groove is located on the side of the mating threaded bore 21 that is adjacent to the bearing. The pushing member 2 further comprises a snap ring 24 adapted to the annular mounting groove, and the snap ring 24 is mounted to the annular mounting groove.
In this embodiment, after the bearing is pushed to the mounting position, the pushing member 2 and the mounting member 1 need to be detached from the output shaft, so that the subsequent use is convenient. At this time, the driving member can rotate the pushing member 2 in the opposite direction only by changing the rotation direction, so as to move in the direction away from the bearing, thereby completing the disassembly. In this embodiment, the pushing member 2 may drive the mounting member 1 to move together by the snap ring 24. The snap ring 24 is installed in the side that cooperates the screw hole 21 and is close to the bearing, and when the side that supports pushing piece 2 and is close to mounting 1 near the bearing, snap ring 24 can take place to touch with mounting 1 to promote mounting 1 together to move towards the direction that keeps away from the bearing.
The mounting part 1 can be more stable to mount by being in threaded fit with the output shaft in specific application, and the snap ring 24 can drive the mounting part 1 to move as well. When the pushing piece 2 rotates until the clamping ring 24 contacts with the mounting piece 1, the clamping ring 24 can be in abutting contact with the mounting piece 1 to be pressed, so that the clamping ring 24 can drive the mounting piece 1 to rotate along with the pushing piece 2, the mounting piece 1 is gradually separated from the output shaft, and finally the disassembly is completed.
In a specific application, the cross-sectional area of the bearing is large, and the contact area of the pushing member 2 with the bearing is too small, which may cause too much stress concentration. Thus, in an embodiment of the present application, the end of the abutment 2 facing the bearing is provided with an abutment portion 25 surrounding the mating threaded hole 21, and the abutment portion 25 is configured to abut against the bearing when the abutment 2 is moved in the axial direction of the output shaft toward the bearing on the output shaft.
In the present embodiment, the pushing portion 25 surrounds the mating threaded hole 21, and the pushing portion 25 extends toward the outside, so that the contact area between the pushing member 2 and the bearing is increased. By extending the pushing part 25 towards the outside, the pushing part 2 can make the pushing force more dispersed when pushing the bearing by the pushing part 2, and reduce the possible loss of the bearing.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples merely represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the invention. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application. Accordingly, the scope of protection of the present application is to be determined by the claims appended hereto.
