Abstract
The invention relates to a self-cooling ball screw assembly, which overcomes the drawbacks of the straight channel structure design mode of the conventional ball screw nut, can improve the alignment of a straight channel and a spiral rollway and has low temperature rise. The self-cooling ball screw assembly mainly comprises a screw shaft, end plug type reversers, a sealing ring, a straight pipe, a nut and a ball, wherein the ball is arranged in a ball circulating rollway which comprises three parts, namely the spiral rollway, a reversed rollway and a straight channel; the spiral rollway consists of the screw shaft and the spiral part of the nut; the reversed rollway consists of the circular arc rollways in the end plug type reversers at the two ends of the nut; and the straight channel consists the straight pipe arranged in the through hole in the nut.
Description
Technical field
The present invention relates to the precision mechanical transmission technology, be more particularly to that traditional relatively screw rod and nut body ball-recirculation raceway are smooth more, in the using process temperature rise lower from the cooling-down type ball screw pair.
Background technique
Ball screw pair is the key feature that lathe and other machines are realized precision mechanical transmission, and the Performance And Reliability of ball screw pair is directly determining the lathe overall performance.Traditional ball screw pair structure composition mainly contains: lead screw shaft, nut, ball and ball reversing device.The internal spiral raceway of lead screw shaft raceway and nut, ball reversing device and nut straight passage are formed closed circulation raceway jointly, thereby make ball can realize closed circulation.In actual production, there are problems such as relatively poor to neutrality, that surface roughness is lower in the processing of ball straight passage in the nut, thereby make the circulation raceway curvature of ball discontinuous, phase mutual friction and collision easily take place in the running, make the friction torque of ball screw pair not steady; Simultaneously, the collision between ball also makes ball screw pair produce noise, in the using process temperature rise bigger, the working life of having reduced ball screw pair.
Summary of the invention
The objective of the invention is to overcome the existing deficiency of straight passage structural design mode of existing ball screw pair nut, provide a kind of can improve straight passage and spiral rolling track to neutral and can reduce the ball screw pair temperature rise from the cooling-down type ball screw pair.
The technological scheme that patent of the present invention solves its technical problem is:
A kind of from the cooling-down type ball screw pair, it mainly is made up of lead screw shaft, end plug type reverser, seal ring, straight-through tube, nut and ball; Described ball is installed in the ball-recirculation raceway, and the ball-recirculation raceway comprises spiral rolling track, reverse raceway and straight passage three parts: spiral rolling track is made up of the spiral part of lead screw shaft and nut; Oppositely raceway is made up of the circular arc raceway in the end plug type reverser at nut two ends; Straight passage is made up of the straight-through tube in the through hole that is installed in nut.
The seal ring of described straight-through tube outside and the through hole of nut are formed the nut cooling chamber.Cooling liquid inlet and cooling liquid outlet are respectively the entrance and exit of cooling liquid.
Described straight-through tube is made by engineering plastics.
Utilization of the present invention is installed in the seal ring of straight-through tube outside and the through hole of nut is formed the nut cooling chamber.Cooling liquid inlet and cooling liquid outlet are respectively the entrance and exit of cooling liquid.The difference of this scheme is the structural type in the circulation straight passage that changes ball, and constituted the nut cooling chamber, so not only can improve the error of centralization of circulation straight passage and spiral rolling track by the size of regulating seal ring, also can reduce the ball screw pair temperature rise.
Beneficial effect of the present invention is: overcome relatively poor to neutrality that the course of working of existing ball nut straight passage occurs, a kind of temperature rise that can lower ball screw pair is provided, and can have made the smooth more ball wire bar pair of ball-recirculation.
Description of drawings:
Fig. 1 is a kind of structural representation from the cooling-down type ball screw pair.
Among the figure: 1 lead screw shaft, 2 end plug type reversers, 3 seal rings, 4 cooling liquids inlet, 5 straight-through tubes, 6 nuts, 7 cooling liquid outlets, 8 balls.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing and embodiment.
The structural representation from the cooling-down type ball screw pair as shown in Figure 1, its structure be mainly by lead screw shaft 1, end plug type reverser 2, and seal ring 3, straight-through tube 5, nut 6 and ball 8 are formed.The ball-recirculation raceway comprises spiral rolling track, oppositely raceway and straight passage three parts: spiral rolling track is made up of the spiral part of lead screw shaft 1 and nut 6; Oppositely raceway is made up of the circular arc raceway in the end plug type reverser 2 at nut 6 two ends; Straight passage is made up of the straight-through tube in the through hole that is installed in nut 65.The seal ring 3 that is installed in straight-through tube 5 outsides is formed the nut cooling chamber with the through hole of nut 6.Cooling liquid inlet 4 and cooling liquid outlet 7 are respectively the entrance and exit of cooling liquid.
Straight-through tube 5 is made by engineering plastic materials, because the engineering plastic surface roughness is lower, and the frictional force of ball and raceway in the time of therefore can reducing ball and enter straight passage, thereby reduction temperature rise; At the outside seal rings 3 of installing of straight-through tube 5, can regulate straight-through tube and reverse raceway to neutrality, thereby the continuity of ball motion when guaranteeing that ball leaves reverser; Seal ring 3 by straight-through tube 5 outsides is formed the nut cooling chamber with the through hole of nut 6, can reduce the frictional heat that produces between ball and the straight passage.
