Description

Technical Field

[0001] This utility model belongs to the field of tooling equipment technology, specifically relating to a bearing installation device. Background Technology

[0002] Bearings are a crucial component of flywheels, and currently, they are typically pressed into the flywheel manually using press-fit equipment. To prevent the bearing from detaching from the flywheel, an interference fit is required between the flywheel and the bearing. Therefore, the internal space provided for the bearing within the flywheel is limited. To successfully press the bearing into the flywheel, a significant amount of time must be spent constantly adjusting the bearing's levelness during the press-fit process. If the bearing is tilted, it cannot be pressed, as this will damage the bearing due to pressure. Such a press-fit operation is not only time-consuming and inefficient, but also prone to bearing damage due to improper operation. Utility Model Content

[0003] To address the problems mentioned in the background art, this utility model provides a bearing installation device. Because the bottom of the pressure seat under the flywheel is an elastic pad, which is soft and easily deformable, when the pressure head presses against the bearing, forcing the bearing into the flywheel, the flywheel also adjusts synchronously to match the flatness or tilt of the bearing. With both tilting in the same direction, the bearing is successfully pressed into the flywheel. Therefore, this bearing installation device is not only simple in structure and low in cost, but also easy and efficient to operate, fully utilizing the softness and deformability of the elastic pad to successfully achieve the bearing pressing operation.

[0004] To achieve the above objectives, according to one aspect of this utility model, the technical solution adopted by this utility model is as follows:

[0005] A bearing installation device for installing a bearing inside a flywheel includes a pressure-applying component and a pressure-bearing component. The pressure-applying component is provided with a movable pressure head, and the pressure-bearing component includes a pressure-bearing seat and an elastic pad. The elastic pad is disposed at the bottom of the pressure-bearing seat, and the pressure head is fixedly disposed on the pressure-bearing seat.

[0006] Preferably, the thickness of the elastic pad is 4 mm to 10 mm.

[0007] Preferably, the top of the pressure bearing head is provided with a first guide head, and the bearing can be sleeved on the first guide head.

[0008] Preferably, the pressure application assembly includes a pressure rod, a guide rod, and an operating handle, wherein the operating handle drives the pressure rod to move up and down along the guide rod.

[0009] Preferably, one end of the pressure rod is provided with the pressure head, and the top end of the pressure head is provided with a second guide head, and the bearing can be sleeved on the second guide head.

[0010] Preferably, the pressure-bearing component further includes a support column and a base, which are fixedly connected. The pressure-bearing seat is disposed on the base, and the pressure-applying component and the pressure-bearing component are connected by a cantilever.

[0011] Preferably, one end of the cantilever is movably sleeved on the support column, the cantilever can move up and down along the support column, or rotate around the support column, and the other end of the cantilever is equipped with the pressure application component.

[0012] Preferably, the pressure bearing seat and the elastic pad are provided with corresponding clearance notches, and the pressure bearing seat and the elastic pad are connected by the clearance notches.

[0013] Preferably, the elastic pad is a soft rubber pad.

[0014] 1. This utility model provides a bearing installation device, including a pressure-applying component and a pressure-bearing component. The pressure-applying component is equipped with a movable pressure head, the top of which is a second guide head. The pressure-bearing component includes a pressure-bearing seat and an elastic pad. The elastic pad is located at the bottom of the pressure-bearing seat, and the pressure-bearing seat is also fixedly equipped with a pressure head. The top of the pressure head is equipped with a first guide head. Bearings can be fitted onto both guide heads. When the bearing is pressed into the flywheel from the top, because the bottom of the pressure-bearing seat is an elastic pad with soft and easily deformable characteristics, when the second guide head presses against the bearing and presses it into the flywheel, the pressure on the flywheel acts on the soft and easily deformable elastic pad. Therefore, the flywheel also adjusts synchronously with the flat or tilted state of the bearing, and the tilting directions of the two tend to be the same, thus successfully pressing the bearing into the flywheel. This bearing installation device is not only simple in structure and low in cost, but also simple and convenient to operate. It utilizes the soft and easily deformable characteristics of the elastic pad to achieve stable and efficient installation of the bearing into the flywheel.

[0015] 2. The bearing seat and the elastic pad are provided with corresponding clearance notches. The clearance notches allow the bearing seat and the elastic pad to be connected by screws, thereby restricting and positioning their relative positions. This prevents the elastic pad from deviating from its predetermined position due to excessive deformation, ensuring the normal operation of the bearing installation equipment.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please check Figures 1 to 4 This utility model discloses a preferred embodiment of a bearing installation device. Operable by means of mechanical force, the device installs the bearing into the flywheel 50. Specifically, the bearing installation device includes four corner supports, a workbench 10 with a flat top, and a pressing device 20 fixed to the workbench with screws. The pressing device 20 applies pressure to a first bearing 60, thereby pressing the first bearing 60 into the flywheel 50. The workbench 10 provides an operating platform and support for the pressing device 20. Specifically, the pressing device 20 includes a support 21, a base 22, a cantilever 23, and pressure application components.

[0032] Specifically, the base 22 is a solid base that supports the entire pressing equipment 20 and is fixed to the top surface of the workbench 10 by screws 30 through its own screw holes 40. Additionally, the support column 21 is a solid column that is directly threaded to one end of the base 22. On the support column 21, the cantilever 23 is movably fitted onto it through a mounting hole (not shown) at one end. The cantilever 23 can move up and down along the central axis of the support column 21 as needed, or it can rotate back and forth on the same plane with the support column 21 as the center. When it is necessary to fix the cantilever 23 to a certain position on the support column 21, it can be locked in place using screws and screw holes on the cantilever 23.

[0033] Furthermore, at the other end of the cantilever 23 away from the support column 21, a pressure-applying assembly for applying pressure to the bearing is installed. This assembly includes a pressure rod 24, a guide rod 25, and an operating handle 26. The guide rod 25 is fixed to the top of the cantilever 23. The top of the pressure rod 24 extends radially and protrudes upwards with a pressure rod head 242. The guide rod 25 passes through the pressure rod head 242, allowing the pressure rod 24 to be sleeved on the guide rod 25, ensuring that the two are coaxially parallel, and the pressure rod 24 can move up and down along the guide rod 25. An operating handle 26 is connected to the side of the cantilever 23 and the pressure rod 24. When external force is applied to the operating handle 26, the operating handle 26 can transmit mechanical force to the pressure rod 24 via gears or a linkage, causing the pressure rod 24 to apply downward pressure to the pre-installed first bearing 60.

[0034] Please continue reading. Figure 1 and Figure 3 A pressure head 241 is provided at the lowest end of the pressure rod 24. To increase the pressure of the pressure rod 24 on the first bearing 60 and to apply pressure to the first bearing 60 repeatedly and evenly, the diameter of the pressure head 241 is preferably smaller than the diameter of the pressure rod 24. Specifically, a second guide head 2411 protrudes downward from the top of the pressure head 241. After abutting against the first bearing 60, the second guide head 2411 can be fully or partially embedded into the shaft hole 61 of the first bearing 60, thereby press-fitting the first bearing 60 into the flywheel 50.

[0035] Furthermore, a pressure seat 221 is provided directly below the pressure head 241, i.e., on the base 22, with the pressure head 241 and the pressure seat 221 positioned opposite each other. Additionally, a first guide head 2212a protrudes upward from the top of the pressure seat 221. A second bearing 70 can be pre-fitted onto the periphery of the first guide head 2212a. Then, under the downward pressure of the pressure head 241, the second bearing 70 is inserted into the flywheel 50. Furthermore, the pressure seat 221 has a certain thickness to absorb and support the pressure from the pressure head 241.

[0036] Furthermore, the bottom of the pressure-bearing seat 221 is provided with an elastic pad 222, both having the same cross-section. In addition, the pressure-bearing seat 221 is also provided with a first clearance notch 2211, corresponding to, as... Figure 4 As shown, the elastic pad 222 is also provided with a second clearance notch 2221. With this design, the screw can pass through the first clearance notch 2211 and the second clearance notch 2221, thereby connecting the bearing seat 221 and the elastic pad 222, restricting and fixing their positions, preventing the elastic pad 222 from deviating from the predetermined position due to excessive deformation, and ensuring the normal working condition of the bearing installation equipment.

[0037] The specific operation process of the bearing installation equipment of this utility model is as follows:

[0038] like Figure 2 As shown, first, adjust the cantilever 23 up and down or left and right so that the pressure head 241 is aligned with the pressure seat 221. Then, pre-install the second bearing 70 on the pressure head 2212 of the pressure seat 221. Next, place the flywheel 50 on top of the second bearing 70 and place the first bearing 60 flat on top of the flywheel 50. Then, hold the operating handle 26 and apply force to move the pressure rod 24 downward, so that the pressure head 241 generates downward pressure on the first bearing 60. During this process, the second guide head 2411 can be partially or completely embedded in the shaft hole 61 in the middle of the first bearing 60. Specifically, when the first bearing 60 is in a flat state, the second guide head 2411 can be fully embedded in the shaft hole 61. Under the pressure of the second guide head 2411, the first bearing 60 can be gradually nested into the flywheel 50, achieving an interference fit with the flywheel. At the same time, the flywheel 50 will also move downward due to the pressure transmitted from the top first bearing 60, and then, under the pressure, it will be sleeved on the outside of the second bearing 70. In this way, the second bearing is pressed into the flywheel 50.

[0039] When the first bearing 60 is tilted, the second guide head 2411 cannot be fully embedded in the shaft hole 61, but is partially embedded. In this state, due to the soft and flexible nature of the elastic pad under the flywheel 50, it can deform under pressure, providing tilt support for the flywheel 50. Therefore, when the first bearing 60 is tilted, under the pressure of the second guide head 2411, the flywheel 50 will dynamically adjust synchronously with the tilt of the first bearing 60, and the tilt directions of the two will tend to be the same. Thus, during the dynamic adjustment of the relative position of the first bearing 60 with the flywheel 50, the first bearing 60 is gradually pressed into the flywheel 50, thereby realizing the press-fitting operation of the first bearing 60. To ensure the softness of the elastic pad 2122 and to provide support for the tilt of the flywheel 50, the elastic pad 222 is preferably made of a soft rubber type, such as rubber, silicone, PVC soft rubber, etc. In particular, the thickness of the elastic pad can be 4 mm to 10 mm, preferably 5 mm.

[0040] The bearing installation equipment of the present invention is not only simple in structure and low in cost, but also simple and convenient to operate. It utilizes the soft and easily deformable properties of the elastic pad 222 to achieve interference fit between the flywheel 50 and the first bearing 60 and the second bearing 70. It is also simple, efficient and convenient to operate.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
