Abstract
The invention provides a multi-purpose high-speed rotating joint. The technical problem to be solved is that currently homemade machine tools generally adopt imported high-speed rotating joints, the elasticity of the spiral spring on the high-speed rotating joints is large and results in the close contact of the static seal ring and the moving seal ring, when in rotation without cooling liquid, frictional heat can easily burn the static and the moving seal rings, explaining why the prior multi-purpose high-speed rotating joint can not run under oil-out conditions. The invention is characterized in that the joint comprises a rotator shaft, bearings, a cooling liquid passage and a static ring body, wherein, the static ring is provided with a septum-type rubber seal ring; a spring compensation device is arranged between the bearing and the sealing ring; the cavity formed between the rotator shaft and the static ring is filled with lubricating mass. The invention is applicable to a high-speed rotating shaft for delivering cooling liquid for the high-speed rotating shaft.
Description
Technical field
The present invention relates to transmit the high speed rotation communicating joint of cooling liquid for the high speed rotating hollow shaft.
Background technique
The high-speed rotating shaft of rotating speed below 20,000 commentaries on classics need be carried cooling liquid such as machine tool chief axis to it when work, high speed rotation communicating joint is to be high-speed rotating shaft transmits cooling liquid such as machine tool chief axis device.Generally adopt the high speed rotation communicating joint of import on the present homemade lathe, it is made up of rotor shaft, bearing, cooling passage, stationary ring body and the helical spring on stationary ring.During use rotor shaft is fixed on the high-speed rotary main shaft, cooling liquid is injected from the cooling passage on the stationary ring, lowers the temperature to operative workpiece.Because helical spring elastic force is bigger, and stationary seal ring is contacted with rotary packing ring closely, when no cooling liquid was rotated (promptly doing changes), dynamic and static seal ring was because of friction generates heat, and helical spring and rotation communicating joint heat up very fast, easily it are burnt out.Therefore present high speed rotation communicating joint can not done running.
Summary of the invention
At the deficiencies in the prior art, the object of the present invention is to provide a kind of high speed rotation communicating joint of doing running that adapts to.
The object of the present invention is achieved like this: it comprises rotor shaft, bearing, cooling passage, stationary ring body, it is characterized in that: establish the diaphragm type rubber seal ring on stationary ring.Because diaphragm type rubber seal ring its elastic force when no external force is less, therefore make the pressure between the dynamic and static seal ring less, the heat that is produced is less, and the intensification that it produced is in the scope of its permission.Be convenient processing, seal ring is arranged on the sheath in the housing, on the step of housing, spring is set, with the machining accuracy of compensation housing and axle.Between bearing and seal ring spring compensator being set, is to be used for compensating the error that bearing wear causes, to guarantee precision.Packing lubrication matter in the chamber that between rotor shaft and stationary ring, forms.
The present invention compares with the prior art scheme, and it can be fit to do running, and practicability of the present invention is improved greatly.
Description of drawings
Further specify the present invention below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the enlarged view of the spring compensator among Fig. 1.
Embodiment
It comprises rotor shaft 1, bearing 3 and 4, cooling passage 2, stationary ring 7 and end cap 8, and diaphragm type rubber seal ring 9 is set between stationary ring and end cap.Because diaphragm type rubber seal ring its elastic force when no external force is less, therefore make the pressure between the dynamic and static seal ring less, the heat that is produced is less, and the intensification that it produced is in the scope of its permission.Be convenient processing, seal ring 5 be arranged on the periphery of sheath 10 of 11 li of housings, and relative with bearing, and the sheath in the housing is arranged on the rotor shaft, and spring 6 is set on the step of housing, with the machining accuracy of compensation housing and axle.Spring compensator (referring to Fig. 2) is set between bearing 4 and seal ring 5, and compensation device is to be made of wavy spring 12 and two annular elastomeric spring abutment 13, and it is the precision that is used for compensating after the bearing wear.Packing lubrication matter in the chamber that between rotor shaft and stationary ring, forms.
Claims (2)
1. high speed rotation communicating joint, it comprises rotor shaft, bearing, cooling passage, stationary ring and end cap, it is characterized in that: the diaphragm type rubber seal ring is set between stationary ring and end cap, between bearing and seal ring, spring compensator is set, packing lubrication matter in the chamber that between rotor shaft and stationary ring, forms, sheath in the housing is arranged on the rotor shaft, and seal ring is arranged on the periphery of sheath and is relative with bearing, on the step of housing spring is set.
2. according to the described high speed rotation communicating joint of claim 1, it is characterized in that: said spring compensator is to be made of wavy spring and two annular elastomeric spring abutment.
