An adjustable oil receiving plate device and control method thereof

Abstract

The invention provides an adjustable oil receiving plate device and a control method thereof, belonging to the technical field of mechanical lubrication. In the present invention, a reversible oil receiving plate is arranged in the box of the reducer, and the oil receiving plate is connected to the driver electrically connected to the controller through a cable, and the oil receiving plate is provided with an oil receiving plate extending to the oil groove of the box body. The oil collecting groove and the oil passage hole with flange make it possible to control the driver to lower the oil receiving plate through the cable when the controller detects the low speed operation of the reducer, and receive the lubricating fluid brought by the gear through the oil receiving plate. After the oil is collected by the oil collecting groove, it flows into the oil groove of the box to realize the lubrication of the bearing. When the controller detects that the gearbox is running at a high speed, it can control the driver to pull the oil receiving plate through the cable to reduce or avoid the oil receiving plate. The collection of lubricating oil can prevent the risk of oil leakage caused by excessive lubricating oil and accumulation on the oil seal, which can not only realize the lubrication of the bearing, but also reduce the oil level of the lubricating oil, reduce the sealing pressure, and reduce the risk of oil leakage.

Description

technical field [0001] The invention relates to the technical field of mechanical lubrication, in particular to an adjustable oil receiving plate device and a control method thereof. Background technique [0002] With the advancement of mechanical automation, the reducer is widely used in modern machinery as a transmission device that matches the speed and transmits torque between the prime mover and the working machine or the actuator. Therefore, improving the performance of the reducer has become a Current industry research focus. [0003] As a general mechanical structure, the reducer has broad application prospects and high market value. However, due to the limitation of the existing reducer structure, there are still problems such as lubrication and sealing. For example, the insufficient amount of lubricating oil will lead to poor operation conditions of the reducer bearing, and it is easy to cause the bearing to lock up under the condition of long-term operation.

Problems solved by technology

However, due to the limitations of the existing reducer structure, there are still problems in lubrication and sealing. For example, insufficient lubricating oil will lead to poor operating conditions of the reducer bearings, and it is easy to cause bearing lockup, Burning and other problems, and in the case of a large amount of lubricating oil, it will increase the sealing pressure of the reducer, which will easily lead to the problem of oil leakage of the reducer, which will not only cause safety hazards to the normal operation of the equipment, but also cause environmental pollution, resulting in Solved the problem of poor performance of the reducer

[0004] At present, the existing reducers on the market use the structure of splash lubrication or oil bath lubrication to lubricate the bearings. However, in order to ensure that the bearings have better lubrication conditions, it is necessary to add the oil level of the reducer to the lowest rolling of the submerged bearings. The middle position of the body, that is, the required lubricating oil level is relatively high. Although it can effectively ensure the lubrication conditions of the bearing, when the reducer is running, it will cause problems such as large oil churning loss, temperature rise and serious heat generation, which will affect the reducer. transfer efficiency

In addition, the higher lubricating oil level is already close to the oil seal lip or has not passed the oil seal lip. The existing reducer structure can only rely on the strength of the lip spring, the correctness of assembly and other oil seal structures, as well as the roughness of the oil seal gear, coaxial The sealing condition is equal to the degree of sealing to achieve the sealing, which leads to the problem of poor sealing due to aging and oil leakage in the case of long-term use, resulting in potential safety hazards and environmental pollution.
