When the upper bearing and the lower bearing are lubricated by adopting thin lubricating oil, the lower press cover is provided with an oil inlet (an A hole in the figure), other oil inlets are closed or blocked, the thin lubricating oil enters from the oil inlet of the lower press cover and flows to the lower bearing through the upper bearing through the oil delivery passage port on the wall of the shaft sleeve, finally the thin lubricating oil is collected to the lower press cover, flows into the oil return hole through the plane inclined plane at the bottom of the inner cavity of the lower press cover and returns to the thin oil station for internal circulation use, and the lubricating oil can take away the heat generated by the upper bearing and the lower bearing when flowing through the upper bearing and the lower bearing, so that the lubricating and cooling effects on the upper bearing and the lower bearing are realized, and the service lives of the upper bearing and the lower bearing are further prolonged. 2. When dry lubricating oil (grease) is adopted, a plurality of oil inlet holes on the lower pressing cover are opened, and the dry lubricating oil is pressed into an oil delivery channel in the shaft sleeve wall through the plurality of oil inlet holes under pressure and an oil outlet formed by an oil delivery channel port to finish the lubrication of the lower bearing and the upper bearing.

The technical scheme is as follows: a vertical shaft type impact crusher thin oil and dry oil universal structure comprises a lower gland, a belt pulley, a lower end bearing, a main shaft inner ring, a shaft sleeve, an upper gland, an upper sealing ring and an upper bearing, wherein a plurality of public oil inlet holes are formed in the lower gland in the vertical shaft type impact crusher; an upper bearing and a lower bearing lubricating oil channel are formed in the wall of the main shaft sleeve, the lower bearing lubricating oil transverse oil outlet is located above the lower bearing, and the upper bearing lubricating oil outlet is located at the upper end of the shaft sleeve and forms an upper bearing transverse oil supply hole together with the upper gland.

Compared with the background art, the utility model not only meets the requirement of the customer for filling the lubricating bearing with dry lubricating oil, but also meets the requirement of the customer for lubricating the bearing with thin lubricating oil; and secondly, the working temperature of the upper bearing and the lower bearing is controlled within a set range by detecting the oil temperature of the oil port by adopting a temperature sensor, so that the service life of the upper bearing and the lower bearing is prolonged by more than three times.

Detailed Description

Example 1: reference is made to figures 1-6. A vertical shaft type impact crusher thin oil dry oil general structure comprises a lower gland 1, a belt pulley 2, a lower end bearing 3, a main shaft 4, a main shaft inner ring 5, a shaft sleeve 6, an upper gland 7, an upper sealing ring 8 and an upper bearing 9, wherein the lower gland 1 in the vertical shaft type impact crusher is provided with a plurality of public oil inlet holes 10; an upper bearing and a lower bearing lubricating oil channel 11 are formed in the wall of the main shaft sleeve 6, the lower bearing lubricating oil transverse oil outlet is located above the lower bearing, and the upper bearing lubricating oil outlet is located at the upper end of the shaft sleeve 6 and forms an upper bearing transverse oil supply hole together with the upper gland 7. The plurality of common oil inlet holes 10 in the lower-pressure end are distributed in a high-low distribution. The lower gland is provided with an oil return hole 12. The common oil inlet 10 is a common oil inlet for both the dilute lubricating oil and the dry lubricating oil. The lower gland is provided with an oil return hole 12 which is a shared hole of thin lubricating oil and dry lubricating oil. The method for switching lubrication of thin oil and dry oil of the shaft type impact crusher comprises the following steps: when a customer needs to lubricate the upper bearing and the lower bearing by adopting thin lubricating oil, one common oil inlet hole 10 in the lower gland is reserved, other common oil inlet holes are closed, and the thin lubricating oil enters the upper bearing and the lower bearing lubricating oil channel 11 of the shaft sleeve wall from the common oil inlet hole under the action of the oil pump, and is supplied to the lower bearing and the upper bearing respectively through the lower bearing lubricating oil transverse oil outlet hole and the upper bearing lubricating oil outlet hole; when a customer needs to lubricate the upper bearing and the lower bearing by using dry lubricating oil, the common oil inlets 10 in the lower gland are fully opened, at the moment, the dry lubricating oil enters the upper bearing and the lower bearing lubricating oil channel 11 of the shaft sleeve wall from the common oil inlets under the action of the pressure pump, the dry lubricating oil is supplied to the lower bearing through the lower bearing lubricating oil transverse oil outlet, the dry lubricating oil is supplied to the upper bearing through the upper bearing lubricating oil outlet, and the upper bearing and the lower bearing are lubricated respectively. The dry lubricating oil is butter.

The oil inlet speed of the thin lubricating oil depends on the oil temperature of the thin lubricating oil in the oil outlet, the oil outlet (oil return port) is provided with a temperature detection probe, and when the oil temperature of the oil outlet (oil return port) is larger than the temperature range built in the controller, the controller instructs the execution mechanism to increase the oil inlet speed, so that the temperature of the bearing can be controlled, the bearing is prevented from being damaged due to overhigh temperature, and the lubricating oil is prevented from being failed due to overhigh temperature.

The oil inlet of the dry lubricating oil is determined by lubricating the bearing after the dry lubricating oil runs for 8 hours under the working condition state.

The optimal lubrication time is before the shift, and when the equipment normally runs and the bearing is at the working temperature, the lubricating grease amount is automatically injected into the lubricating metering device, so that the temperature of the bearing can be controlled, the bearing is prevented from being damaged due to overhigh temperature, the bearing can be lubricated, and the bearing is prevented from being damaged due to oil loss.

It is to be understood that: although above-mentioned embodiment is right the utility model discloses a design has done more detailed word description, but these word descriptions, are only right the utility model relates to a simple word description of idea, rather than right the utility model relates to a restriction of idea, any do not surpass the utility model relates to a combination, increase or the modification of idea all fall into the utility model discloses a within the protection scope.
