Description
Technical field
The invention relates to linear guide rail circulating device, its linear guides is generally the linear transmission that accurate control is provided, and is widely used on manipulator, industrial machine, machinery industry, automation equipment, measurement machine and the electronic equipment.
Background technique
Linear guide apparatus, main start principle is that the rolling of utilization rolling unit between slide rail and slide block causes relative movement between the two, and the unit of rolling allows rolling unit finish do action for to finish the motion of unlimited stroke so must design the path of a circulatory system.
Yet the formation of first circulatory system of rolling generally is designed to the individual part compound mode such as the Japan Patent spy opens the 2002-54633 communique, the rolling element retainer 11 of its three kinds of configurations, 12,13 with return flow line 14 and backflow commutator (forming) spare part respectively for independently separating by 15a and 15b, this spare part is all non-to be constituted for one with slide block body 4, be to be combined into slide block movement spare with slide block body 4, its shortcoming is that spare part too much can be because the offset that spare part cooperates produces the unit of rolling beats in that circulation time is abnormal, and then the situation with noise of having some setbacks that causes turning round, and spare part also can make inconvenient and time-consuming the taking a lot of work of its assembling too much.
Secondly the first circulatory system of another kind of rolling is shown in U.S. Pat 4662763; The circulatory system of its unit of rolling, mainly be being constituted by two J-shapeds to cutting the semicanal body, this kind design refluxes the not loading zone of ball partly can reduce the offset of cooperation for integral type, but it must make the design of cooperation and the dividing plate that this body must install the location in addition additional on slide block, so assembling is difficult; Hold the space that lubricant grease flows and in body, there is no, so lubricated being difficult for; And since body be split as that to prolong horizontal cutting be two halves, when ball entered body by the pearl groove of load, body was subjected to differential seat angle that angle that ball impacts strength and level split the position apart from little, caused to make up body and separate easily.
Moreover as the design of Japan Patent JP3349238; The circulatory system of its unit of rolling, mainly be to constitute by four semicircular U-shaped pipes with ball retainer groove, and the fractionation direction and the ball retainer groove part quadrature of its combination halfbody, the major defect of this design be to roll strength angle that unit loaded with split line and overlap, be subject to the assembled state influence when causing the unit of rolling in the combination body, to move and produce unstable the rolling, and make up and be subjected to rolling unit's impact when body moves in the unit of rolling, the doubt of splitting is also arranged.
In sum, the linear guides circulatory system remains to be improved to progress greatly in fact.
