Abstract
The invention relates to a T-shaped feed screw nut, and belongs to the field of machine tools. The T-shaped feed screw nut is provided with a nut and is characterized in that: one side of each thread of the nut is provided with an oil groove, and the other side of each thread of the nut is also provided with an oil groove opposite to the oil groove; a lubricating oil hole is formed on a nut root at the oil groove at intervals of one thread; and an oil inlet hole is axially formed on the side wall of the nut. The defect that when a T-shaped feed screw and the nut transfer large torque, the contact surface between the feed screw and the nut cannot be truly lubricated is overcome, an auxiliary device is not needed and the size of the nut is not increased; the T-shaped feed screw nut has a simple structure and is safe and reliable; and the service life of the feed screw and the nut can be prolonged.
Description
Technical field
The present invention relates to machine tool field, at length say it is the T type feed screw nut of a kind of lathe with transmitting large torque.
Background technique
As everyone knows, existing T type nut all is to process the T type screw thread that adapts with screw mandrel on workpiece, comes transmitting torque by the rotation with screw mandrel.The screw thread that matches with nut for the precision inevitable requirement screw mandrel that obtains workpiece motion s will have higher roughness, in transmitting large torque, one side of screw mandrel and nut will contact closely, that gives screw mandrel and nut like this has lubricatedly brought great inconvenience, traditional lubricating can only be to add lubricant oil at screw mandrel and the discontiguous side of nut, and really needing a side of lubricant oil, because what contact during transmitting large torque between the two is very tight, lubricant oil can't enter at all, so not only influence kinematic accuracy, accelerate the wearing and tearing of nut and screw mandrel simultaneously, seriously shorten the life-span of nut, T type nut becomes easily damaged parts in the time of a lot.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of novel T type nut, under the situation of using conventional lubrication, can make the real lubricating contact face of T type feed screw nut energy in transmitting large torque, the working life of improving machining accuracy and prolongation nut, screw mandrel.
The technical solution adopted for the present invention to solve the technical problems is: a kind of T type feed screw nut, be provided with nut, it is characterized in that being processed with oil groove in every button screw thread one side of nut, while is on the opposite of this oil groove, the opposite side of screw thread is processed with oil groove equally, at the bottom of oil groove place nut tooth, be provided with an oilhole, axially be processed with oil inlet hole at the nut sidewall every a button screw thread.
The invention has the beneficial effects as follows, overcome T type screw mandrel and nut can't really lubricate screw mandrel and nut when transmitting large torque surface of contact, need not increase any auxiliary device, do not increased the nut size, simple in structure, safe and reliable, can prolong screw mandrel, nut life-span.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the three-dimensional cross-sectional schematic of Fig. 1
1. nuts among the figure, 2. oil is stifled, 3. oil inlet hole, 4. oilhole, 5. oil groove.
Embodiment
In Fig. 1, Fig. 2, Fig. 3, the present invention is on the basis of general T type nut, the center of eccentric nut certain apart from S, with R is that radius is processed with the oil groove 5 that can store lubricant oil in every button screw thread one side of nut 1, while is on the opposite of this oil groove 5, the opposite side of screw thread also is processed with oil groove 5 in the same way, at the bottom of oil groove 5 place's nut teeth, be provided with an oilhole 4 every a button screw thread, nut 1 sidewall axially be processed with oil inlet hole 3, the unwanted auxiliary hole that stays during the processing and lubrication oilhole on nut 1 sidewall is blocked with oil stifled 2.
