Description

Technical Field

[0001] This utility model relates to the field of speed reducer installation technology, and in particular to a bearing pressure device for speed reducer assembly. Background Technology

[0002] A speed reducer is an independent mechanical device composed of transmission components such as gears and worm gears. It is mainly used to reduce speed and increase torque, and is widely used for power matching between prime movers and driven machines.

[0003] To ensure smooth operation of the reducer drive shaft, a bearing is usually installed at its end. The inner side of the bearing and the end of the drive shaft are generally interference-fitted. During installation, pressure needs to be applied to the bearing. Existing installation methods mainly involve placing a sleeve on top of the bearing and applying pressure to the top of the sleeve, or alternately tapping the connection point on top of the bearing. During this process, the sleeve is prone to displacement, resulting in inaccurate tapping positions and affecting the quality of the bearing. It is also necessary to use sleeves with different inner diameters according to the shaft end size, which is very inconvenient. Alternating tapping at multiple points causes the bearing to tilt to a certain extent, which not only makes installation difficult but also easily damages the shaft surface. Utility Model Content

[0004] This utility model addresses the deficiencies in the prior art by providing a bearing pressure device for speed reducer assembly.

[0005] This utility model is achieved through the following technical solution: A bearing pressure application device for assembling a speed reducer includes a base, a support seat, a support sleeve, a washer, a guide rod, and a pressure application mechanism. The support seat is fixedly mounted on the top of the base, the support sleeve is snapped onto the top of the support seat, the washer is fixedly mounted on the inner side of the top of the support sleeve, the guide rod is disposed on the outer sides of both sides of the support seat, and the pressure application mechanism is sleeved on the outer side of the guide rod. The pressure application mechanism includes a connecting frame, a guide ring, a mounting cover, a guide rail, a sliding plate, a pressure application rod, a drive rod, a retaining ring, a rotating cover, and a pressure-receiving rod. The guide ring is fixedly mounted on the bottom end of the connecting frame, the mounting cover is fixedly mounted on the inner side of the top of the connecting frame, the guide rail is fixedly mounted on the inner side of the top of the mounting cover, the sliding plate is snapped onto the inner side of the guide rail, the pressure application rod is fixedly mounted on the bottom end of the sliding plate, the drive rod is fixedly mounted on the top of the sliding plate, the retaining ring is fixedly mounted on the outer side of the mounting cover, the rotating cover is sleeved on the outer side of the mounting cover, and the pressure-receiving rod is fixedly mounted on the top of the rotating cover.

[0006] In a preferred embodiment of the present invention, the top of the drive rod passes through the mounting cover and extends to the top outer side of the rotating cover, and the top of the rotating cover and the mounting cover are provided with an arc-shaped groove that mates with the drive rod. The rotating cover presses against the drive rod, causing the sliding plate to move within the guide rail, thereby changing the position of the pressure rod and facilitating pressure on the top of the bearing.

[0007] In a preferred embodiment of this utility model, a groove for engaging with a retaining ring is provided on the inner side of the rotating cover; The retaining ring is mainly used to effectively limit the rotation of the cover, ensuring its effective connection with the mounting cover.

[0008] In a preferred embodiment of the present invention, a lifting ring is provided at the top of the support sleeve, an insertion hole that mates with the support sleeve is provided at the top of the support base, the top of the pad ring is higher than the top surface of the support sleeve, and the pad ring is made of plastic. The washer ring mainly provides effective support for the drive shaft shoulder, preventing damage to the drive shaft caused by hard contact.

[0009] In a preferred embodiment of this utility model, the bottom of the mounting cover is provided with 3-6 sets of guide rails, and the bottom of the pressure rod is lower than the lower surface of the mounting cover.

[0010] The beneficial effects of this utility model are: After the bearing pressure device for the gear reducer supports the drive shaft, the bearing is fitted onto the end of the drive shaft. The position of the pressure rod is adjusted by rotating the cover to position the pressure rod at the top of the inner ring of the bearing. Then, pressure is applied to the pressure rod, so that the pressure rod applies pressure evenly and synchronously to the top of the inner ring of the bearing at multiple points, thereby achieving rapid installation and reducing the risk of damage to the shaft and bearing.

[0014] like Figure 1-4 The illustrated bearing pressure application device for speed reducer assembly includes a base 1, a support seat 2, a support sleeve 3, a washer 4, a guide rod 5, and a pressure application mechanism 6. The support seat 2 is fixedly mounted on the top of the base 1, the support sleeve 3 is snapped onto the top of the support seat 2, the washer 4 is fixedly mounted on the inner side of the top of the support sleeve 3, the guide rod 5 is disposed on the outer sides of both sides of the support seat 2, and the pressure application mechanism 6 is sleeved on the outer side of the guide rod 5. The pressure application mechanism 6 includes a connecting frame 61, a guide ring 62, a mounting cover 63, a guide rail 64, a sliding plate 65, a pressure rod 66, and a drive rod 67. The retaining ring 68, rotating cover 69, and pressure rod 610 are provided. The guide ring 62 is fixedly installed at the bottom of the connecting frame 61. The mounting cover 63 is fixedly installed on the inner side of the top of the connecting frame 61. The guide rail 64 is fixedly installed on the inner side of the top of the mounting cover 63. The sliding piece 65 is locked on the inner side of the guide rail 64. The pressure rod 66 is fixedly installed at the bottom of the sliding piece 65. The drive rod 67 is fixedly installed on the top of the sliding piece 65. The retaining ring 68 is fixedly installed on the outer side of the mounting cover 63. The rotating cover 69 is sleeved on the outer side of the mounting cover 63. The pressure rod 610 is fixedly installed on the top of the rotating cover 69.

[0015] Specifically, the top of the drive rod 67 passes through the mounting cover 63 and extends to the top outer side of the rotating cover 69. The top of the rotating cover 69 and the mounting cover 63 are provided with arc-shaped grooves that cooperate with the drive rod 67. The inner side of the rotating cover 69 is provided with a groove that cooperates with the retaining ring 68. The top of the support sleeve 3 is provided with a lifting ring. The top of the support base 2 is provided with an insertion hole that cooperates with the support sleeve 3. The top of the washer ring 4 is higher than the top surface of the support sleeve 3. The washer ring 4 is made of plastic. The bottom of the mounting cover 63 is provided with 3-6 sets of guide rails 64. The bottom of the pressure rod 66 is lower than the lower surface of the mounting cover 63.

[0016] In this embodiment, a suitable support sleeve 3 is selected according to the size of the shaft so that the inner washer 4 can support the shaft shoulder, ensuring that the drive shaft is vertically locked into the support sleeve 3. Then, the guide ring 62 is sleeved on the outside of the guide rod 5, and the bearing is placed on the top of the drive shaft. Then, the rotating cover 69 is rotated on the top of the mounting cover 63, so that the arc groove on the top of the rotating cover 69 applies pressure to the drive rod 67, causing the sliding piece 65 to slide in the guide rail 64 to adjust the position of the pressure rod 66.

[0017] Furthermore, adjusting the rotating cover 69 allows the drive rod 67 to be adjusted synchronously, thereby ensuring that the pressure rods 66 are distributed in a circular pattern. After adjusting the pressure rods 66 to be located at the top of the bearing inner ring, the guide ring 62 falls on the surface of the guide rod 5 until the bottom of the pressure rod 66 contacts the top of the bearing inner ring. At this time, the hydraulic press applies pressure to the pressure rod 610, which allows the pressure rods 66 to apply pressure to the top of the bearing inner ring synchronously and evenly. The bearing is quickly installed by applying pressure evenly at multiple points.
