Description

Technical Field

[0001] The utility model relates to the technical field of guide wheels, in particular to a wear-resistant and high-temperature-resistant guide wheel. Background Art

[0002] A guide wheel is a reaction element of a torque converter, which is fixed to a guide wheel shaft or a guide wheel sleeve in one direction through a one-way clutch. It is a pulley used to guide a transmission belt through an obstacle or change the direction of the transmission belt. It is located between a turbine and a pump wheel. Usually, it is processed from high-carbon steel and then surface-hardened (surface quenched), and has the characteristics of high temperature resistance and high strength.

[0003] After retrieval, the prior art (publication number: CN212899608U) records that "a high-temperature-resistant and high-strength guide wheel includes a bearing rod. One side of the bearing rod is connected with a guide wheel body, and a lubrication mechanism is installed at the top of the bearing rod. The lubrication mechanism internally includes a storage tank fixedly connected to the top of the bearing rod. The top of the storage tank is provided with a feed port, and a rubber plug is connected inside the feed port. In the utility model, under the action of the lubrication mechanism, lubricant can be added to the storage tank through the feed port. The water-absorbing rope clamped in the conduit can smear the lubricant in the storage tank on the surface of the guide wheel body to perform smear maintenance on it, preventing the guide wheel body from being worn after long-term use and having too much rotational resistance. By rotating the hand-tightening bolt, one side of the guide wheel body can be squeezed to stop its rotation, facilitating other processing operations for workers, changing the situation where other guide wheel bodies could not be fixed in the past, and improving the flexibility of the device."

[0004] Although the high-temperature-resistant and high-strength guide wheel in the prior art achieves the effects of lubrication and fixation, there are still some deficiencies: after lubrication through a water-absorbing rope in the existing high-temperature-resistant and high-strength guide wheel, the outer surface adheres to the lubricating liquid and cannot penetrate into the connection gap between the bearing and the shaft rod, resulting in waste of some lubricating liquid. Secondly, due to a large amount of heat generated by high-speed rotation and friction during the use of the existing guide wheel, although the guide wheel has high-temperature resistance, it lacks an active and fast heat dissipation structure, resulting in components such as its transmission belt being affected by high temperature and possibly slipping. Summary of the Utility Model

[0005] To overcome the defects existing in the prior art, a wear-resistant and high-temperature-resistant guide wheel is provided to solve the problems that the existing high-temperature-resistant and high-strength guide wheel lacks an active and fast heat dissipation function, and has poor lubrication effect and waste of lubricating liquid.

[0006] To achieve the above object, a wear-resistant and high-temperature-resistant guide wheel is provided, including: a guide wheel body, the guide wheel body includes a ceramic wheel body on the outside, a bearing is embedded inside the ceramic wheel body, a shaft rod is axially fixed inside the bearing, and a heat-conducting metal sheet is provided inside the ceramic wheel body. A fixing component and a lubricating component are fixed on the outside of the shaft rod. The fixing component includes a fixing ring.

A hose is connected to the lower end of the liquid storage tank. The lubricating component includes a semi-ring body, and the upper side of the semi-ring body is connected to the liquid storage tank through a hose.

[0007] Further, the heat-conducting metal sheets are arranged on the inner wall and the outer wall of the ceramic wheel body, and the heat-conducting metal sheet arranged on the outer wall of the ceramic wheel body is in contact with the external environment.

[0010] Further, a liquid filling port is opened at the upper end of the liquid storage tank, a filter screen is arranged inside the liquid storage tank cavity, and the hose is connected to the lower side of the filter screen.

[0011] Further, a slow flow cavity is opened inside the semi-ring body, a connection hole is opened at the upper side of the slow flow cavity, and the connection hole is connected to the hose.

The fixing component 2 includes a fixing ring 21, and a liquid storage tank 25 is slidably connected to one side of the fixing ring 21 facing the ceramic wheel body 11. A brake pad 28 is arranged on the outside of the liquid storage tank 25. At the same time, a hose 27 is connected to the lower end of the liquid storage tank 25. The lubricating component 3 includes a semi-ring body 31, and the upper side of the semi-ring body 31 is connected to the liquid storage tank 25 through the hose 27.

[0025] Specifically, the guide wheel body 1, the fixing component 2 and the lubricating component 3 constitute the main structure of the wear-resistant and high-temperature resistant guide wheel involved in this application. The shaft rod 13 included in the guide wheel body 1 is in a fixed connection state, and both the fixing component 2 and the lubricating component 3 are in the same fixed connection state as the shaft rod 13.

[0026] Specifically, the inner end of the heat-conducting metal sheet 14 is arranged around the inner wall of the wheel groove of the ceramic wheel body 11 and is flush with the inner wall of the wheel groove. At the same time, the heat-conducting metal sheet 14 located inside the ceramic wheel body 11 can conduct the internal heat outward, thereby realizing rapid heat dissipation.

[0027] Specifically, the brake pad 28 is made of rubber material, and when it is squeezed, it contacts the ceramic wheel body 11 to statically limit it.

[0028] As Figure 2 mixed Figure 4 shown in the figure, the fixing ring 21 is fixed on the outer wall of the shaft rod 13, and a screwing plate 22 is arranged on the outer wall of the fixing ring 21.

The hose 27 is connected to the lower side of the filter screen 26.

[0029] As a preferred implementation manner, by arranging multiple filter screens 26, the lubricating liquid is filtered to prevent impurities from entering the connection part of the bearing 12 and causing wear of the bearing 12.

At the same time, the heat-conducting metal sheet embedded inside the ceramic wheel body can strengthen the self-structural strength of the ceramic wheel body. During use, through the liquid storage tank and the hose included in the fixing component, the lubricating fluid inside is guided downward into the lubricating component, and then through the semi-annular body, the flow-attenuating cavity and the seepage hole included in the lubricating component, the lubricating fluid inside is guided to the connection part between the bearing and the shaft rod, thereby realizing the internal lubrication of the bearing connection and reducing the waste of the lubricating fluid. When fixing, by rotating the threaded rod and cooperating with the screwed plate, the slider is driven to push the liquid storage tank to move, and then the brake pad is pushed to move towards the outer ceramic wheel body and squeeze and rub against it, realizing the fixation of the guide wheel after shutdown, and being integrated with the liquid storage tank, saving the assembly space and being convenient for use and operation.

[0034] The wear-resistant and high-temperature-resistant guide wheel of the present utility model can effectively solve the problems that the existing high-temperature-resistant and high-strength guide wheels lack the active and rapid heat dissipation function, and have poor lubrication effect and waste of lubricating fluid. On the basis of the existing wear-resistant and high-temperature-resistant guide wheel technology, the structure of the fixed lubrication device is simplified, and the heat dissipation effect is accelerated. At the same time, the lubrication effect is enhanced, and the waste of the lubricating fluid is reduced.
