Abstract
The invention provides a large and heavy type elevator-shaped nut with a wedge-shaped lubricating oil cavity. The technical scheme provided by the invention is as follows: the large and heavy type elevator-shaped nut with the wedge-shaped lubricating oil cavity comprises a nut body, wherein conical oil storage cavities are arranged at two ends of the nut body, wedged-shaped removed faces are machined on side faces, with certain length of thread teeth, at two end parts of the nut body to form the wedge-shaped oil cavity, and an oil injection hole is further formed in the middle part of the nut body. The large and heavy type elevator-shaped nut disclosed by the invention has the beneficial effects that a screw rod and the nut are fully lubricated with a good lubrication effect, friction force can be effectively lowered, and friction heat can be reduced.
Description
Technical field
The present invention relates to a kind of trapezoidal nut, relate in particular to large-scale, the heavy up-down trapezoidal nut of a kind of wedge shape lubricant oil cavate.
Background technique
Current up-down trapezoidal screw, pair of nut transmission are to large-scale, heavy development, and up-down trapezoidal screw, pair of nut adopt grease lubrication.At present leading screw, nut lubricant reservoir structure: 1) no special lube chamber is by leading screw, the oil storage of nut gap; 2) in the middle of nut, be processed into local curved surface near the oiling aperture on the side thread form face and form small oil cavity; 3) the car clearance groov is made oil pocket in the nut inner thread chamber.Above-mentioned lubricant reservoir structure is science not, and leading screw, nut lubrication effect are undesirable.Because current leading screw, nut lubricant reservoir structure are only considered to inject lubricating grease in leading screw, the nut rotation cavity, lubricating grease leans on leading screw or nut rotation to bring in leading screw, the nut surface of contact; Concerning large-scale, heavy trapezoidal screw, lift nut pair; Because leading screw, nut interface pressure are big, lubricating grease is difficult to get between the surface of contact, and nut two ends screw thread is owing to the reason cutter relieving of processing in addition; When work, contact earlier with leading screw thread form face; The two ends screw thread scrapes off the lubricating grease on the leading screw thread form face, and it is bad to cause leading screw, nut to lubricate, big, the heating of frictional force.
Summary of the invention
The present invention be directed to the existing in prior technology shortcoming, and provide a kind of leading screw, nut to lubricate fully, effective, can effectively reduce frictional force, large-scale, the heavy up-down trapezoidal nut of wedge shape lubricant oil cavate of the heat of reducing friction.
The present invention realizes through following technical measures: large-scale, the heavy up-down trapezoidal nut of a kind of wedge shape lubricant oil cavate; It comprises nut body; The two ends of nut body are provided with the taper shoe cream room; Be processed with wedge shape on the side of the worm tooth of the two end part certain-length of said nut body and remove face and constitute the wedge shape oil pocket, the middle part of said nut body also is provided with oil hole.Being arranged so that when nut and leading screw cooperate of wedge shape oil pocket has certain interval storage lubricant oil between the two.
Concrete characteristics of the present invention also have, and the axial length of above-mentioned said wedge shape oil pocket is the length of 1～1.5 button screw thread.
The beneficial effect of this programme can be learnt according to the narration to such scheme; The present invention is processed with the wedge shape oil pocket at the nut two ends, and the nut two ends not only store lubricating grease, and lubricating grease leans on wedge cavities to get in leading screw, the nut surface of contact; Leading screw, nut lubricate fully; Effective, reduce frictional force, the heat of reducing friction.

Embodiment
For clearly demonstrating the technical characterstic of this programme, through an embodiment, this programme is set forth below.
As shown in the figure; Large-scale, the heavy up-down trapezoidal nut of a kind of wedge shape lubricant oil cavate; It comprises nut body 1; The two ends of nut body 1 are provided with taper shoe cream room 2, are processed with wedge shape on the side of the worm tooth of two end part 1～1.5 button reach of said nut body 1 and remove face and constitute wedge shape oil pocket 3, and the middle part of said nut body 1 also is provided with oil hole 4.
The present invention can pass through or adopt existing techniques in realizing without the technical characteristics of describing; Repeat no more at this; Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited in above-mentioned giving an example; Variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present invention also should belong to protection scope of the present invention.
