Technical Field

[0001] This invention relates to the field of planetary carrier assembly technology, and more particularly to a planetary gear assembly device. Background Technology

[0002] In the existing technology, when assembling large sliding bearing planetary gears, the vertical installation of the planetary gear axis into the planetary carrier can easily cause damage to the bearing shell. In order to avoid damage to the bearing shells on both sides of the planetary gear, the current method is to hoist the planetary gear into the planetary carrier with the planetary carrier axis horizontal. However, this assembly method is inefficient and has a high safety risk during the planetary carrier flipping and hoisting process.

[0003] Therefore, there is an urgent need for a planetary gear assembly device to solve the aforementioned problems. Summary of the Invention

Each locking component includes a fixing block and a screw, which is threadedly connected to the fixing block and whose end can abut against the outer ring of the slewing bearing.

[0012] As a preferred technical solution for a planetary gear assembly device, the support component includes a tray, an adjusting plate, and a support base. The adjusting plate is installed above the support base, and the distance between the adjusting plate and the support base is adjustable. The tray is installed above the adjusting plate and can slide on the adjusting plate. The planetary gears are installed above the tray and can slide on the tray.

[0033] like Figures 1-3 As shown, this embodiment provides a planetary gear assembly device for mounting planetary gears 200 onto mounting positions 1001 on a planetary carrier 100. The planetary gear assembly device includes a planetary carrier support assembly 1 and a planetary gear support assembly 2.

[0034] Specifically, the planetary carrier support assembly 1 includes a slewing bearing 11, on which the planetary carrier 100 is rotatably mounted, and the planetary carrier 100 and the slewing bearing 11 are coaxially arranged. The planetary gear support assembly 2 is disposed on one side of the planetary carrier support assembly 1, and includes a support member 21. The planetary gears 200 are mounted on the support member 21, and the axis of the planetary gears 200 is parallel to the axis of the planetary carrier 100. One end of the support member 21 is connected to the mounting position 1001, and the planetary gears 200 can slide to the mounting position 1001 via the support member 21. During assembly, the planetary carrier 100 is first mounted on the slewing bearing 11 to enable the planetary carrier 100 to rotate, with the axis of the planetary carrier 100 in the vertical direction. Then, the planetary gears 200 are mounted on the support member 21. When the planetary carrier 100 rotates to a preset position, the support member 21 is connected to the mounting position 1001, and then the planetary gears 200 are pushed to the mounting position 1001, thus realizing the installation of the planetary gears 200 into the planetary carrier 100. Compared to the existing planetary gear hoisting assembly method, in this embodiment, the axes of both the planetary gear 200 and the planetary carrier 100 are vertical. The planetary carrier 100 is stably mounted on the slewing bearing 11, and the planetary gear 200 is stably mounted on the support component 21, preventing swaying. This improves the stability of the installation of the planetary carrier 100 and the planetary gear 200, reduces safety risks, and simplifies the assembly operation of the planetary gear 200, thus improving work efficiency.

[0035] In this embodiment, as Figure 1 and Figure 2 As shown, the planetary gear assembly device also includes a base plate 3. The planetary carrier support assembly 1 and the planetary gear support assembly 2 are both installed on the base plate 3, so that the planetary gear assembly device is assembled into a single structure, which is convenient for movement and adjustment.

[0036] Furthermore, the planetary carrier support assembly 1 also includes a positioning ring 12, which is mounted above the outer ring 112 of the slewing bearing 11, and the end of the planetary carrier 100 is embedded in the positioning ring 12. On one hand, this fixes the planetary carrier 100 above the slewing bearing 11; on the other hand, the planetary carrier 100 will automatically align itself when it falls into the positioning ring 12, which provides positioning for the planetary carrier 100. In this embodiment, the positioning ring 12 is mounted on the outer ring 112 with screws.

[0037] The planetary carrier support assembly 1 also includes a pad 15, which is mounted on the base plate 3. The inner ring 111 of the slewing bearing 11 is fixed to the pad 15 with screws. More preferably, the planetary carrier support assembly 1 further includes a third driving member, which is driven and connected to the outer ring 112 of the slewing bearing 11. In this embodiment, the third driving member is a motor, and a gear is provided on the motor's drive shaft. The gear meshes with the outer ring 112 of the slewing bearing 11, enabling the motor to drive the outer ring 112 of the slewing bearing 11 to rotate, thereby achieving automatic rotation of the planetary carrier 100. In other embodiments, the output end of the motor is connected to a worm gear, and a worm wheel is provided on the outer ring 112 of the slewing bearing 11. The worm gear meshes with the worm wheel to drive the outer ring 112 of the slewing bearing 11 to rotate.

[0038] Preferably, the planetary carrier support assembly 1 further includes multiple auxiliary support components 13, which are mounted on the base plate 3 and arranged around the bottom of the planetary carrier 100. Each auxiliary support component 13 includes a base 131 and a support rod 132. One end of the support rod 132 is threaded to the base 131, and the other end can abut against the bottom of the planetary carrier 100. On the one hand, the auxiliary support components 13 provide support for the planetary carrier 100, preventing it from tipping over and improving its structural stability. On the other hand, when the support rod 132 of the auxiliary support component 13 rotates threadedly relative to the base 131, its height can be adjusted, thus adapting to various models of planetary carriers 100 and improving its versatility.

[0039] Preferably, the planetary carrier support assembly 1 further includes multiple locking components mounted on the base plate 3. These locking components are positioned circumferentially around the slewing bearing 11. Each locking component includes a fixing block 141 and a screw. The screw is threadedly connected to the fixing block 141, and its end abuts against the outer ring 112 of the slewing bearing 11. In this embodiment, the fixing block 141 has a second threaded hole 1411, the direction of the central axis of the second threaded hole 1411 being radially aligned with the slewing bearing 11. The screw is threadedly connected to the second threaded hole 1411. When the planetary carrier 100 rotates to a preset position, the screw is threadedly connected to the fixing block 141, and its end abuts against the outer ring 112 of the slewing bearing 11. Multiple screws simultaneously abut against the outer ring 112 of the slewing bearing 11 circumferentially. Through friction, the outer ring 112 of the slewing bearing 11 is locked, preventing the planetary carrier 100 from continuing to rotate. When the outer ring 112 of the slewing bearing 11 rotates by the motor, the planetary carrier 100 can also be prevented from continuing to rotate by the motor self-locking.

[0040] Furthermore, such as Figure 1 and Figure 3As shown, the support component 21 includes a tray 211, an adjusting plate 212, and a support base 214. The adjusting plate 212 is installed above the support base 214, and the distance between the adjusting plate 212 and the support base 214 is adjustable. The tray 211 is installed above the adjusting plate 212 and can slide on the adjusting plate 212. The planetary gear 200 is installed above the tray 211 and can slide on the tray 211. The tray 211 includes a first working position and a second working position. When the tray 211 is in the first working position, the tray 211 is connected to the mounting position 1001. When the tray 211 is in the second working position, the planetary carrier 100 can continue to rotate. The adjusting plate 212 is mounted above the support base 214, and the distance between the adjusting plate 212 and the support base 214 is adjustable, so that the height of the adjusting plate 212 and the support plate 211 is adjustable. This allows the height of the planetary gear 200 to be adjusted to a preset height to adapt to the height of the planetary carrier 100, meeting the installation requirements of planetary carriers 100 of various sizes and improving versatility. When the planetary carrier 100 rotates to the preset position, the support plate 211 moves to the first working position and is connected to the mounting position 1001, driving the planetary gear 200 to slide relative to the support plate 211 onto the mounting position 1001. After the planetary gear 200 is assembled, the support plate 211 is driven to move to the second working position, and the planetary carrier 100 continues to rotate to install the next planetary gear 200 on the mounting position 1001. In this embodiment, the mounting position 1001 is circular, and the end of the support plate 211 is provided with a semi-circular groove to avoid the mounting position 1001, so that the planetary gear 200 falls into the mounting position 1001.

[0041] Preferably, the support component 21 further includes a plurality of positioning blocks 215, which are mounted on the adjusting plate 212. The positioning blocks 215 are used to position the first working position of the pallet 211, thereby improving the connection accuracy between the pallet 211 and the mounting position 1001. In this embodiment, there are four positioning blocks 215. Two positioning blocks 215 are located on both sides of the pallet 211. Steps are provided at the ends of both sides of the pallet 211 near the planetary carrier 100 to prevent the pallet 211 from shifting along the sides. The other two positioning blocks 215 abut against the step surface to limit the pallet 211 from moving further toward the planetary carrier 100.

[0042] In this embodiment, the support component 21 further includes multiple adjusting studs 216 and locking elements 217. The support base 214 is provided with a first threaded hole, and the adjusting plate 212 is provided with a through hole corresponding to the first threaded hole. The adjusting studs 216 pass through the through hole and are threadedly connected to the first threaded hole. The locking elements 217 are used to fix the adjusting plate 212 onto the adjusting studs 216. In this embodiment, a support flange is provided on the adjusting studs 216, which is used to support the adjusting plate 212. The locking elements 217 include a first nut, a second nut, and a third nut. The first nut and the second nut are located above the adjusting plate 212, and the second nut is located between the first nut and the adjusting plate 212. When the second nut is tightened, it can clamp the adjusting plate 212 together with the support flange to prevent the adjusting plate 212 from moving axially along the adjusting studs 216. The first nut and the second nut are tightened together to prevent the first nut and the second nut from rotating during operation. The third nut is threaded onto the adjusting stud 216 and located at the bottom of the first threaded hole. When the third nut is tightened, the adjusting stud 216 cannot rotate relative to the first threaded hole. When it is necessary to adjust the height of the adjusting plate 212, loosen the third nut and rotate the adjusting stud 216 so that the adjusting plate 212 can be adjusted in height relative to the support 214. After adjustment, tighten the third nut to prevent the adjusting stud 216 from rotating accidentally.

[0043] During the adjustment of the adjusting plate 212, if the adjusting plate 212 is not level, preferably, a spherical washer and a conical washer are provided between the second nut and the adjusting plate 212 to adapt to the tilt state of the adjusting plate 212. The second nut can also be locked when it is tilted relative to the adjusting plate 212.

[0044] Since the planetary gear 200 is relatively heavy, preferably, an auxiliary plate 213 is connected to the end of the adjusting plate 212 away from the planetary carrier support assembly 1. A first driving component is mounted on the auxiliary plate 213, which can push the planetary gear 200 to the mounting position 1001. In this embodiment, the first driving component is a jack or a servo motor, and the auxiliary plate 213 provides a mounting structure for the jack and a support surface for the jack.

[0045] To prevent wear on the planetary gear 200 when the first driving member drives it to rotate, the planetary gear support assembly 2 further includes a buffer block 22. The buffer block 22 is disposed between the planetary gear 200 and the first driving member, and the first driving member drives the planetary gear 200 to move through the buffer block 22. In this embodiment, the buffer block 22 is made of nylon to prevent the first driving member from causing wear on the planetary gear 200.

[0046] Preferably, a second driving member is mounted on the auxiliary plate 213. The second driving member is driven and connected to the support plate 211, and can drive the support plate 211 to move closer to or away from the planetary carrier 100. In this embodiment, a connector is provided at the end of the support plate 211 away from the planetary carrier 100, and the connector is connected to the second driving member. In this embodiment, the second driving member is a bidirectional jack or a servo motor, which can push and pull the support plate 211, thereby driving the support plate 211 to move closer to or away from the planetary carrier 100. In other embodiments, the second driving member is driven by a hydraulic cylinder, a hydraulic oil cylinder, or a servo motor.

[0047] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
