Abstract
The utility model provides a spindle box with oil immersed type annular seal. The spindle box comprises a box body and a spindle. Through holes are formed in the front face and in the back face of the box body. The spindle is matched with the through holes. The box body comprises a support seat and a top cover. The support seat is provided with a containing part. A circle of annular first groove is arranged on the top face of the support seat. A sealing ring is arranged inside the first groove. The top cover is fixed on the top face of the support seat. An oil flinger is arranged inside the containing part. The oil flinger is fixed on the spindle. A spiral second groove is arranged on the end face of the oil flinger. Oil liquid for cooling is arranged on the bottom of the box body. At least part of the oil flinger is immersed into the oil liquid. When the spindle box is used, a rotating disc rotates at high speed along with the spindle, the lower portion of the rotating disc is immersed into the oil liquid, and the oil liquid enters into the second groove and is thrown out along the spiral direction of the second groove. The oil liquid which is thrown out can take away the heat inside the spindle box so that the heat dissipation performance of the spindle box is good.
Description
Technical field
The utility model relates to a kind of bearing ring lathe for machining, relates in particular to a kind of for the main spindle box with oil immersed type ring packing on the bearing ring lathe for machining.
Background technology
The bearing ring turning lathe is a kind of lathe that is specifically designed to the machining bearing lasso, mainly comprises elevator, feed mechanism, cutting agency, clamp mechanism, knife rest and frame.The rear end of clamp mechanism links to each other with main shaft, and main shaft drives the clamp mechanism rotation, for supports main shaft, also is provided with a main spindle box between main shaft and the clamp mechanism, is provided with through hole on the both ends of the surface of main spindle box, and main shaft matches with through hole.During use, the main shaft High Rotation Speed, and can produce friction between the through hole, this friction can produce very large heat, causes the temperature of main spindle box to raise cause danger.The temperature of main spindle box raises simultaneously, also can cause the lubricating oil on the main shaft thinning, can not play due lubricant effect, and then further increases the weight of the friction heat radiation, therefore is necessary to change.
Summary of the invention
The utility model provides a kind of main spindle box with oil immersed type ring packing for deficiency of the prior art, and cooling is good in the main spindle box.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of main spindle box with oil immersed type ring packing, comprise casing and main shaft, be provided with through hole on the two sides, front and back of described casing, described main shaft matches with described through hole, described casing comprises a supporting seat and a top cover, be provided with an accommodation section on the described supporting seat, be provided with the first groove of a ring shape on the end face of described supporting seat, be provided with sealing ring in described the first groove, described top cover is fixed on the end face of described supporting seat, be provided with a disc in the described accommodation section, described disc is fixed on the described main shaft, is provided with spiral the second groove on the end face of described disc, the bottom of described casing is provided with the fluid of cooling usefulness, and described disc has at least part to immerse in the described fluid.During use, rotating disk is with the main shaft High Rotation Speed, and the bottom of rotating disk is immersed in the fluid, and fluid enters in the second groove, and along with the hand of spiral of the second groove throws away.These fluid that throw away can be taken away the heat in the main spindle box, so that the main spindle box heat radiation is good.The sealing ring of simultaneously supporting seat end face setting can form close contact with the bottom surface of top cover, prevents oil liquid leakage.
In the technique scheme, preferred, described top cover links to each other with described supporting seat by bolt.
The beneficial effects of the utility model are: during use, rotating disk is with the main shaft High Rotation Speed, and the bottom of rotating disk is immersed in the fluid, and fluid enters in the second groove, and along with the hand of spiral of the second groove throws away.These fluid that throw away can be taken away the heat in the main spindle box, so that the main spindle box heat radiation is good.
