Abstract
The invention discloses a kind of screw mandrel bottom bearing oil-proof device, including screw mandrel and the bearing block and bearing installed in screw mandrel bottom, step is integrally formed with above the bottom bearing block of screw mandrel, ring-type oil-containing groove is provided with the lower end of step, the external diameter of described ring-type oil-containing groove is more than the external diameter of step.Compared with prior art, the beneficial effects of the invention are as follows：Step on screw mandrel has blocked the connection gap between ring-type oil-containing groove and screw mandrel, be prevented effectively from it is dirty oil under ooze, rubber washer further increases the sealing between ring-type oil-containing groove and screw mandrel simultaneously, external diameter of the external diameter of ring-type oil-containing groove more than step, the dirty oil flow down from screw mandrel can be caught, prevent dirty oil from entering bearing, be prevented effectively from the situation generation that dirty oil damages bearing.
Description
Technical field
The present invention relates to a kind of screw mandrel bottom bearing oil-proof device.
Background technology
In existing vertical processing there is following defect in Z axis screw mandrel bottom, after production and processing a period of time, dirty oil on screw mandrel can be past dirty along screw mandrel, although being mounted with inner frame sealing ring on the bearing block of screw mandrel lower end, but gap is still present, dirty oil still can cause bearing damage from the gap into bearing.
The content of the invention
The present invention needs the above mentioned problem for solving to be directed to above-mentioned the deficiencies in the prior art, and provides a kind of screw mandrel bottom bearing oil-proof device.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of screw mandrel bottom bearing oil-proof device, including screw mandrel and the bearing block and bearing installed in screw mandrel bottom, step is integrally formed with above the bottom bearing block of screw mandrel, ring-type oil-containing groove is provided with the lower end of step, described ring-type oil-containing groove is threadedly attached on screw mandrel, rubber washer is additionally provided between ring-type oil-containing groove and screw mandrel, the external diameter of described ring-type oil-containing groove is more than the external diameter of step.
Described rubber washer is step rubber washer.
Ring-type sponge ring is provided with described ring-type oil-containing groove, described ring-type sponge ring size shape is adapted to ring-type oil-containing groove, and described ring-type sponge ring is provided with breach.
Compared with prior art, the beneficial effects of the invention are as follows：Step on screw mandrel has blocked the connection gap between ring-type oil-containing groove and screw mandrel, be prevented effectively from it is dirty oil under ooze, rubber washer further increases the sealing between ring-type oil-containing groove and screw mandrel simultaneously, external diameter of the external diameter of ring-type oil-containing groove more than step, the dirty oil flow down from screw mandrel can be caught, prevent dirty oil from entering bearing, be prevented effectively from the situation generation that dirty oil damages bearing.
