example

[0021] Example: The shaft oil supply hydrostatic spindle is applied to the bearing testing instrument to test the bearing. The specific implementation steps are as follows:

[0022] step 1.

[0023] Clean the white steel oil tank of the hydraulic station, and inject filtered 20# clean hydraulic oil. The main components of the hydraulic station: oil pump, filter, accumulator, heater, radiator, liquid level thermometer, connect the oil inlet pipe and oil return pipe, open the hydraulic station to suspend the main shaft in a static state.

[0024] Step 2.

[0025] Install the shaft oil hydrostatic spindle on the test platform, and install the pulley or coupling, and connect to the motor. Install sensors related to bearing detection and axial and radial force devices, and insert the mandrel into the series of Morse taper holes of the main shaft or on the outer Morse taper.

[0026] Step 3.

[0027] When the hydraulic station is turned on, turn on the motor to drive the main sh...

Abstract

The invention relates to an oil static pressure main shaft for shaft oil supply, which belongs to the mechanical engineering technical field. The invention is characterized in that the oil static pressure main shaft for shaft oil supply is composed for the main shaft, a front end cover, a regulating ring, a bearing bush, a rear end cover and a bush seat. The high pressure oil is directly entered into an oil chamber of the bearing bush through an oil nozzle, an oil orifice is drilled on the main shaft, therefore the high pressure oil is supplied to the radial oil chamber through the oil orifice of the main shaft for thrusting the oil chamber. The main shaft is suspended in the bearing bush by an oil membrane, the hydraulic oil flowed out of the oil chamber is returned back to a hydraulic station through an oil return hole of the bearing bush. The oil static pressure main shaft has the effect and performance that a restrictor and a bush sleeve are removed, the shaft but the bush sleeve is used for oil supply, and the structure is simplified. The oil static pressure main shaft solves the obstruction problem of the restrictor and reduces the complex degree of mechanical treatment and assembly process.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering and relates to an oil static pressure main shaft designed through a shaft oil supply structure. Background technique [0002] The oil static pressure spindle has been widely used in the mechanical industry. The traditional oil static pressure technology is that the high pressure oil is supplied from the bushing through the restrictor. The small hole of the throttle is generally 0.5-0.6mm, which is very easy to block, resulting in stuffy car phenomenon. Such as image 3 As shown: 8 symmetrical oil chambers and oil return grooves are opened on the 2 oil supply sleeves. The material of the sleeves is generally tin bronze or cast Babbitt alloy. The processing of the oil chambers is usually done by turning, milling, and EDM. The bushing needs to be installed into the bearing bush, usually by cold fitting or interference fit pressing. Therefore it is difficult to ensure the coaxiality a...
