Technological scheme
In order to solve above-mentioned technical barrier; The utility model has designed a kind of thin oil lubricant bearing support seal arrangement, and it comprises bearing support, it is characterized in that: have on the inner hole wall of said bearing support near both ends of the surface and decide the plate mounting groove; Decide to be equipped with in the plate mounting groove sealing and decide plate; Decide plate mounting groove top and have capilar bore, capilar bore communicates through splash oil pipe hole and oil return slotted eye, on the return opening on the oil return slotted eye venting gas appliance is housed; Saidly decide the plate mounting groove and have the air-flow steering channel near installing on the end face one side inner hole wall, the air-flow steering channel is connected with air inlet system through the air-flow suction port.
Said sealing is decided plate and is comprised and decide ring and thimble that thimble elasticity is connected on the outer side surface of deciding ring.
Said capilar bore aperture is 0.8~1.2mm, and the aperture, oil pipe hole of splashing is 5.6~6.5mm.
Said air-flow steering channel width is 6.5~7.5mm, and the degree of depth is 9.5~10.5mm, and the air-flow steering channel becomes 75 ° with the bearing support axial direction.
Said air inlet system comprises air-strainer; The air-strainer outlet end is connected to air compressor; The air compressor export pipeline is connected on the air-flow suction port of air-flow steering channel, main line ball valve, needle-valve, pressure gauge outfit is installed on the connecting pipeline of said air compressor and air-flow suction port successively and divides the pipeline ball valve.
Said venting gas appliance comprises three-way pipe, and three-way pipe one port is received the return opening on the bearing support oil return slotted eye, and second port is connected to air filter, and the 3rd port takes back the oil return hydraulic station through pipe fitting.
Beneficial effect
When rotating shaft is rotated in bearing support; The lubricant oil countershaft lubricates and reduces rotational resistance; Sealing is decided plate resistance and is blocked the less amount of lubrication oil of splashing out, makes it get into the oil return hydraulic station along the capilar bore and the oil pipe hole of splashing, and air inlet system forms the pneumostop effect through the air blast in bearing support of air-flow suction port; Increase the sealability of whole bearing support, prolonged the working life of bearing support.
