Description

Technical Field

[0001] This utility model relates to a bearing installation tool for replacing bearings in equipment such as centrifuges. Background Technology

[0002] In the process of producing potassium chloride from salt lake brine, scraper centrifuges are used for material separation. Due to the presence of a large amount of potassium chloride dust in the working environment, these dust particles can enter the bearings, increasing wear and causing them to easily break. Damaged bearings must be replaced promptly. Furthermore, commonly used equipment on potassium chloride production lines, such as flotation cells, hot melt tanks, crystallizers, filters, and centrifuges, typically contains rotating parts such as bearings. These bearings wear down over time, requiring continuous replacement of damaged or expired bearings to maintain proper equipment operation.

[0003] The lack of suitable bearing installation tools presents significant inconvenience for maintenance work. Current methods typically require multiple maintenance personnel to work together. One worker manually secures the bearing to the end of the shaft, while others use hammers, chisels, or similar tools to tap the bearing, gradually installing it onto the bearing housing on the shaft through mechanical force. This method is time-consuming, labor-intensive, and inherently dangerous. Insufficient force makes installation difficult, while excessive force, resulting in uneven stress on the bearing due to limited impact, can easily damage it, reducing its lifespan and potentially harming equipment. Furthermore, the operation increases the risk of finger injuries to maintenance personnel, and prolonged maintenance time disrupts normal production.

[0004] The purpose of this invention is to solve the problems of inconvenient, time-consuming and labor-intensive bearing installation in existing equipment. Utility Model Content

[0005] To solve the above problems, this utility model provides a bearing installation tool, including an installation cylinder 1, an installation retaining ring 2, and an installation rod 3. The installation cylinder 1 is a straight cylinder, and the installation retaining ring 2 is a circular ring. The inner diameter of the installation retaining ring 2 corresponds to the diameter of the rotating shaft. The installation retaining ring 2 is fixedly installed inside the installation cylinder 1, near the front opening of the installation cylinder 1. A space for accommodating the bearing is formed between the installation retaining ring 2 and the front opening of the installation cylinder 1. The front end of the installation rod 3 is fixedly connected to the rear end of the installation cylinder 1 by multiple connecting rods 31. The axis of the installation rod 3 is collinear with the axis of the installation cylinder 1. A stop block 32 is provided at the rear end of the installation rod 3.

[0006] When using this utility model, the front end of the mounting cylinder 1 is sleeved onto the bearing to be installed, so that the mounting ring 2 abuts against the bearing. Hold the mounting rod 3 to keep the mounting cylinder 1 aligned with the bearing. Then, use a hammer or other tool to strike the stop block 32 at the rear end of the mounting rod 3. The mounting ring 2 impacts the bearing, so that the bearing is evenly stressed, thereby installing the bearing onto the bearing seat.

[0007] This utility model features an installation cylinder 1 with an installation retaining ring 2 positioned near the front opening. A space for accommodating the bearing is formed within the installation cylinder 1, located in front of the installation retaining ring 2. The installation cylinder 1 allows for positioning, while the installation retaining ring 2 ensures even force distribution on the bearing, preventing damage due to uneven force. This allows for simple and quick bearing installation, solving the problems of inconvenient, time-consuming, and labor-intensive bearing installation in existing equipment.

[0008] Preferably, it also includes a mounting slider 4, the mounting rod 3 is a straight rod, the mounting slider 4 is cylindrical, the inner diameter of the mounting slider 4 corresponds to the diameter of the mounting rod 3, and the slider can be slidably sleeved on the mounting rod 3.

[0009] By setting a gripping mounting slider 4 on the mounting rod 3, when installing the bearing, holding the mounting slider 4 can keep the mounting cylinder 1 aligned with the bearing. When the stop block 32 at the rear end of the mounting rod 3 is struck, it can prevent the mounting rod 3 from vibrating and moving forward, which could cause injury to the maintenance personnel's hands.

[0010] Preferably, a rubber pad 41 is provided on the outer side of the mounting slider 4. By providing a rubber pad 41 on the outer side of the mounting slider 4, the grip comfort can be improved, the friction can be increased, and the sliding can be prevented from causing the mounting slider 4 to fall out of the hand.

[0011] Preferably, the front end of the mounting rod 3 is provided with a mounting plate 33, which is circular and has a diameter larger than that of the mounting rod 3. The mounting rod 3 is fixedly connected to each connecting rod 31 through the mounting plate 33, and the front end of the mounting slider 4 is provided with an annular striking block 42.

[0012] By setting an installation plate 33 at the front end of the installation rod 3 and a striking block 42 at the front end of the installation slider 4, when the bearing is small and easy to install, tools such as hammers can be avoided. When installing the bearing, hold the stop block 32 at the rear end of the installation rod 3 with one hand and the installation slider 4 with the other hand, push the installation slider 4 to slide forward along the installation rod 3, so that the striking block 42 hits the installation plate 33, and the bearing can be installed, saving time and effort.

[0013] Preferably, the distance between the mounting ring 2 and the front opening of the mounting cylinder 1 is 3cm. By setting the distance between the mounting ring 2 and the front opening of the mounting cylinder 1 to 3cm, a space can be formed between the mounting ring 2 and the front opening of the mounting cylinder 1 to accommodate the bearing, which facilitates the installation of the bearing and also prevents the front end of the mounting cylinder 1 from conflicting with other parts of the equipment and affecting the installation of the bearing.

[0014] Preferably, a protective pad 21 is provided on the side of the mounting ring 2 facing the opening of the mounting cylinder 1. By providing a protective pad 21 on the side of the mounting ring 2 facing the opening of the mounting cylinder 1, the protective pad 21 can separate the mounting ring 2 and the bearing during bearing installation, preventing the mounting ring 2 from directly contacting the bearing, further protecting the bearing and reducing the possibility of bearing damage from impacts.

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figure 1 and Figure 2 As shown, the bearing installation tool includes an installation cylinder 1, an installation retaining ring 2, an installation rod 3, and an installation slider 4. The installation cylinder 1 is a straight cylinder with an internal cavity that accommodates the bearing and the equipment shaft.

[0022] The mounting ring 2 is a circular ring, and its inner diameter corresponds to the diameter of the rotating shaft. The mounting ring 2 is fixedly installed inside the mounting cylinder 1, near the front opening of the mounting cylinder 1. A space for accommodating the bearing is formed between the mounting ring 2 and the front opening of the mounting cylinder 1. When installing the bearing, the bearing is snapped into the space located at the front end of the mounting ring 2 inside the mounting cylinder 1.

[0023] The inner diameter of the mounting ring 2 corresponds to the diameter of the rotating shaft, meaning that the inner diameter of the mounting ring 2 is equal to or slightly larger than the diameter of the rotating shaft, allowing the rotating shaft to pass through the inside of the ring.

[0024] The distance between the mounting ring 2 and the front opening of the mounting cylinder 1 can be set according to the size of the bearing, as long as it can accommodate the bearing. In this embodiment, the distance between the mounting ring 2 and the front opening of the mounting cylinder 1 is 3cm.

[0025] The distance between the mounting ring 2 and the front opening of the mounting cylinder 1 is set to 3cm. The space between the mounting ring 2 and the front opening of the mounting cylinder 1 can accommodate the bearing, which facilitates the installation of the bearing and prevents the front end of the mounting cylinder 1 from conflicting with other parts of the equipment and affecting the installation of the bearing.

[0026] By setting up an installation cylinder 1, and setting an installation retaining ring 2 inside the installation cylinder 1 near the front opening, a space is formed inside the installation cylinder 1 in front of the installation retaining ring 2 to accommodate the bearing. The installation cylinder 1 can be used for positioning, and the installation retaining ring 2 can make the bearing bear evenly stressed, preventing damage caused by uneven stress on the bearing, thus allowing the bearing to be installed simply and quickly.

[0027] A protective pad 21 is provided on the side of the mounting ring 2 facing the opening of the mounting cylinder 1. By providing the protective pad 21 on the side of the mounting ring 2 facing the opening of the mounting cylinder 1, the protective pad 21 can separate the mounting ring 2 and the bearing during bearing installation, preventing the mounting ring 2 from directly contacting the bearing, further protecting the bearing and reducing the possibility of bearing damage from impacts.

[0028] like Figure 1 and Figure 3 As shown, the mounting rod 3 is a straight rod extending in the front-to-back direction. The axis of the mounting rod 3 is collinear with the axis of the mounting cylinder 1. A mounting plate 33 is provided at the front end of the mounting rod 3, and a stop block 32 is provided at the rear end. The mounting plate 33 is circular, and its diameter is larger than that of the mounting rod 3. The mounting plate 33 is fixedly connected to the rear end of the mounting cylinder 1 through multiple connecting rods 31.

[0029] The stop block 32 and the mounting rod 3 can be fixed by threaded connection or welding.

[0030] The mounting rod 3 and the mounting cylinder 1 are fixedly connected by multiple connecting rods 31, which can install bearings with longer shafts. The position of the shaft end can be observed through the gaps between the connecting rods 31, preventing the shaft end from being undetected when it abuts the front end of the mounting rod 3, which could lead to bearing installation failure or even damage to the equipment.

[0031] The mounting slider 4 is cylindrical, and its inner diameter corresponds to the diameter of the mounting rod 3, allowing it to slide onto the mounting rod 3. A circular striking block 42 is provided at the front end of the mounting slider 4, and a rubber pad 41 is fitted onto the outer side of the mounting slider 4.

[0032] The inner diameter of the mounting slider 4 corresponds to the diameter of the mounting rod 3, meaning that the inner diameter of the mounting slider 4 is equal to or slightly larger than the diameter of the mounting rod 3, so that the mounting slider 4 can be fitted onto the mounting rod 3 and slide back and forth along the mounting rod 3.

[0033] By providing a gripping mounting slider 4 on the mounting rod 3, the mounting cylinder 1 can be kept aligned with the bearing when the bearing is installed. When the stop block 32 at the rear end of the mounting rod 3 is struck, it prevents the mounting rod 3 from vibrating and moving forward, thus preventing hand injury to maintenance personnel. A rubber pad 41 is provided on the outside of the mounting slider 4 to improve grip comfort, increase friction, and prevent slippage that could cause the mounting slider 4 to fall out of the hand.

[0034] A striking block 42 is set at the front end of the mounting slider 4. When the bearing is small and easy to install, tools such as hammers can be eliminated. When installing the bearing, hold the stop block 32 at the rear end of the mounting rod 3 with one hand and hold the mounting slider 4 with the other hand. Push the mounting slider 4 forward along the mounting rod 3 so that the striking block 42 hits the mounting plate 33, and the bearing can be installed, saving time and effort.

[0035] like Figure 4 As shown, when in use, if the bearing 52 on the rotating shaft 51 of the mechanical equipment 5 is small and easy to install, the front end of the mounting cylinder 1 is sleeved on the bearing 52 to be installed, so that the mounting ring 2 abuts against the bearing 52, and the end of the rotating shaft 51 passes through the mounting ring 2. Hold the stop block 32 at the rear end of the mounting rod 3 with one hand to keep the mounting cylinder 1 aligned with the bearing, and hold the mounting slider 4 with the other hand to push the mounting slider 4 to slide forward along the mounting rod 3. The mounting plate 33 is struck by the striking block 42, and the bearing is struck on one side by the mounting ring 2 to make the bearing evenly stressed. The bearing is then installed on the bearing seat 53.

[0036] If the bearing 52 on the rotating shaft 51 of the mechanical equipment 5 is too large to install, it is necessary to use a hammer or other tools to tap it. In this case, the front end of the mounting cylinder 1 is fitted onto the bearing 52 to be installed, so that the mounting ring 2 abuts against the bearing 52. The end of the rotating shaft 51 passes through the mounting ring. Hold the mounting rod 3 with one hand to keep the mounting cylinder 1 and the bearing 52 aligned. Use the other hand to tap the stop block 32 at the rear end of the mounting rod 3 with a hammer or other tools. The bearing 52 is impacted by the mounting ring 2, so that the bearing 52 is evenly stressed, thereby installing the bearing 52 onto the bearing seat 53.

[0037] This utility model provides an installation cylinder 1 with an installation retaining ring 2 located near the front opening inside the installation cylinder 1. A space for accommodating the bearing is formed inside the installation cylinder 1 in front of the installation retaining ring 2. The installation cylinder 1 can be used for positioning, and the installation retaining ring 2 can ensure that the bearing is evenly stressed, preventing damage caused by uneven stress. This allows for simple and quick bearing installation.

[0038] By setting a gripping mounting slider 4 on the mounting rod 3, when installing the bearing, holding the mounting slider 4 can keep the mounting cylinder 1 aligned with the bearing. When the stop block 32 at the rear end of the mounting rod 3 is struck, it can prevent the mounting rod 3 from vibrating and moving forward, which could cause injury to the maintenance personnel's hands.

[0039] By setting an installation plate 33 at the front end of the installation rod 3 and a striking block 42 at the front end of the installation slider 4, when the bearing is small and easy to install, tools such as hammers can be avoided. When installing the bearing, hold the stop block 32 at the rear end of the installation rod 3 with one hand and the installation slider 4 with the other hand, push the installation slider 4 to slide forward along the installation rod 3, so that the striking block 42 hits the installation plate 33, and the bearing can be installed, saving time and effort.

[0040] It should be noted that the above embodiments are illustrative of the present invention and not intended to limit the present invention.
