Abstract
The invention relates to a ball screw high-speed mute structure which comprises a fixing base, a screw axle, at least two opposite ball ring, a sealing sheet, and an annular sheath. Wherein, said fixing base has a through inner hole in the center; the inner hole has a screw groove; at least a couple of hollow grooves are arranged at the fixing base; the ball ring along the hollow groove is arranged into the inner hole to make the ball rings cover the outer surface of screw axle with full circumference; the ball ring in ellipse shape to avoid jam of ball to realize the mute function in high speed rotation of screw axle.
Description
Technical field
The present invention is relevant a kind of high speed muting structure for ball screw, especially refer to that a kind of ball screw designs the device mode and the assembled configuration of its rolling steel ball, make screw axis when rotating, particularly the unlikely noise that sends friction and bump of each rolling steel ball under the high speed rotating situation makes property easy to assembly and solemn silence all greatly promote.
Background technique
Press the structure design of ball screw, when metal steel ball is rolled in the spiral grooves on screw axis, the sound that unlikely generation metal steel ball clashes into mutually, therefore in known technical, be the distance piece that filling has plastic cement between two metal steel balls, make to reach the sound of avoiding sending the metal bump.
So open in the 2000-355278 case in the Japan Patent spy, the artificer has invented the device that a kind of ball screw avoids producing noise, in the design of this case for being provided with a kind of steel ball retainer, two sheet holding parts before and after being configured to of retainer has, between two sheet holding parts, linking wafer warpage portion, be packed to steel ball by the Ullage between two sheet holding parts, be provided with in the fixed base endoporus of ball screw again and comprise the spiral grooves that to hold wafer warpage portion, the gyrotron of approximate ㄇ shape also must be set in the fixed base top simultaneously, and the hole is engraved in open many places in the fixed base bottom, so that the press block of steel ball retainer is packed into by engraving the hole, whole construction goes out circulating steel ball sliding channel tank circuit footpath.Generally speaking the complex structure of this case, trickle part is more and be difficult for assembling, and because of filling in one by one by the roll piece of a steel ball and a steel ball retainer between screw axis and the fixed base in the Element Design, so it is higher to produce time cost, be unfavorable for the reduction of cost of goods manufactured, also be easier to produce the fault shortcoming because of part number is numerous.
Open in the 2001-99257 case in the Japan Patent spy in addition, be provided with most steel balls and a steel ball retainer equally, most plastic cement distance pieces on the steel ball retainer are provided with linking strip in periphery, insert mouth and conveying end and must be provided with on the fixed base, make the steel ball and the circulating rolling in spiral grooves of steel ball roll piece that retainer constitutes that are strip; Its shortcoming is that the roll piece of strip all has the head end of linking, this head end will cause roll piece to roll in spiral grooves to have some setbacks, the steel ball of strip roll piece and steel ball retainer are in the gyrotron circulating path of the approximate ㄇ shape of fixed base outside simultaneously, may produce that steel ball rolls in non-circular arc path and tool smoothness not to the utmost is more undesirable for the ball screw quietness.
Be with, it can more progress greatly so that the rotation solemn silence raising of ball screw in order to ask the present invention, has to meet being suitable for of more kinds of industries, reduces with being easy to assembling and manufactured good reject ratio, to promote the improved purpose of with quality as fundamental invention.
Summary of the invention
Main purpose of the present invention promptly provides a kind of high speed muting structure for ball screw, and it has when the screw axis high speed rotating, can reach quiet function in the moving process of rolling steel ball and screw rod spindle guide.
Secondary objective of the present invention is that a kind of high speed muting structure for ball screw is provided, and is easy to assembling in its structure design and promotes usefulness in man-hour, is suitable for a large amount of manufacturings, can reduce the generation of reject ratio simultaneously, produces the advantage that effectively reduces manufacture cost indirectly.
For reaching above-mentioned goal of the invention, the present invention in textural mainly be provided with fixed base, screw axis, more than two in pairs to ball ring, diaphragm seal and ring set form; Described fixed base is provided with the perforation endoporus in central authorities, be provided with spiral grooves in its endoporus, the hollow out caulking groove of at least one pair of is that relative position is arranged on the fixed base in pairs, the ball ring is followed in the endoporus that the hollow out caulking groove is placed in fixed base, but the ball ring wholecircle week that makes at least one pair of is coated on the outer surface of screw axis, its ball ring oval in shape is rolled rolling steel ball swimmingly and is not produced obstruction, quiet effect when reaching the screw rod high speed rotating.
Wherein more than at least two in pairs to the ball ring be oppositely arranged for adopting with the circumference in equal parts angle, therefore the steel ball on each ball ring is to contact with screw axis in the special angle scope, make the steel ball rolling path of ball ring for oval smoothly, retardancy will not be produced, the smooth degree that screw axis rotates can be promoted.And quiet chain belt of the ring-type on the ball ring and steel ball are the one combination, and be convenient again fast when making assembling.
As for detailed construction, application principle, effect and the effect of the embodiment of the invention, then the explanation of doing with reference to following adjoint can be understood completely.
