Elastic metal-plastic bushing and elastic metal-plastic bushing temperature measuring assembly

Abstract

The invention provides an elastic metal plastic bearing bush and a temperature measurement assembly of the elastic metal plastic bearing bush. The elastic metal plastic bearing bush comprises a bush base body (2) and an elastic metal plastic compound material bush face (1) which is arranged on the bush base body (2), the elastic metal plastic bearing bush is provided with an installation groove (4), the installation groove (4) is used for installing a temperature sensing device (3), is arranged at the oil outlet edge (E) of the elastic metal plastic bearing bush and is provided with an opening facing towards the oil outlet edge (E), and an end of the installation groove (4) along the extension direction is located on the working face of the elastic metal plastic bearing bush. According to the elastic metal plastic bearing bush and the temperature measurement assembly of the elastic metal plastic bearing bush, the actual operating temperature of the working face can be monitored accurately, and timely warning and controlling can be achieved according to the temperature, so that effective safe operation monitoring can be conducted on the plastic bearing bush, and bush burning accidents can be avoided.

Description

technical field [0001] The invention relates to the field of bearings, in particular to an elastic metal-plastic bearing bush and a temperature-measuring assembly for the elastic metal-plastic bearing bush. Background technique [0002] Elastic metal-plastic bearings are a new type of bearings that have emerged in the past two decades. They have many excellent properties and can replace traditional Babbitt bearings. They are widely used in hydropower equipment, mill gearboxes, metallurgical equipment and other industries. Timely and accurate monitoring of the actual operating temperature of the elastic metal-plastic bearing is an important link to ensure the normal operation of the elastic metal-plastic bearing during long-term use. [0003] In the prior art, most of the conventional monitoring methods for temperature monitoring of Babbitt alloy bearings are still used, that is, the actual operating temperature of elastic metal-plastic bearings is monitored by monitoring the...

AI Technical Summary

Problems solved by technology

In this utility model, there is an oil guide hole on the working surface of the bearing pad leading to the temperature measuring hole where the temperature measuring element is installed. If the oil guide hole does not open an oil outlet hole on the side of the bearing pad, due to the contact between the pad surface and the temperature measuring element The distance is far, and the oil in the oil guide hole cannot be discharged during normal operation, so it is difficult for the oil guide hole to send the hot oil on the surface of the bearing pad to the temperature measuring element. At this time, the oil that the temperature measuring element can touch is still the base oil. The oil in the body, and the oil in the tile body is difficult to flow, so it basically maintains the same temperature as the surrounding environment, that is, despite the existence of the oil guide hole, the temperature measured by the temperature measuring element is still the same as the temperature of the tile body around the temperature measuring element Roughly the same temperature, it is difficult to accurately measure the temperature of the working surface of the bearing pad

And if in order to maintain the flow of oil in the oil guide hole, when the oil outlet hole is set on the side of the bearing bush to communicate with the oil guide hole, although the oil in the oil guide hole has fluidity, due to the height of the oil level in the working oil tank of the thrust pad Generally, it is more than 10mm higher than the thrust tile surface. Therefore, in fact, the setting of the oil outlet hole will cause the oil guide hole to communicate with the lubricating oil in the oil tank. Therefore, the temperature of the lubricating oil measured by the temperature measuring element in the temperature measuring hole is seriously affected by the temperature in the oil tank. It is also difficult to obtain accurate measurement results due to the influence of oil temperature

Therefore, the above temperature measurement method disclosed in this utility model patent cannot accurately measure the actual temperature on the working surface of the elastic metal-plastic bearing pad.

[0006] In short, the plastic bearing manufacturing industry and users have been trying to improve the monitoring method of the actual operating temperature of the elastic metal plastic bearing for many years, but have not found an effective method for accurately monitoring the working surface temperature of the plastic bearing during long-term operation.
