Abstract
The invention discloses a digit-control high-accuracy speed reducer, comprising a base 1, a worm 2, and a worm rod 3. The worm rod 3 is composite one that dividing the screw line of screw rod into two sections at 1/2 length and along the radius, while one section is arranged with a worm rod axle 3-1 and another end is arranged with the worm rod sheath 3-2, the worm rod sheath 3-2 is mounted on the worm rod axle. When in use, based on the application of speed reducer, the invention accurately machines the combine faces 3-1.1 and 3-2.1 of two sections of worm rod, to correct and eliminate the production error of worm and worm rod and the transmission space caused by the abrasion, to control the transmission space under 0.005mm, to confirm the accurate transmission of speed reducer. The invention has compact structure, high positioning accuracy and stable transmission, without noise.
Description
One, technical field
The present invention relates to a kind of machining equipment, particularly the numerical control machine tool retarder.
Two, background technique
Existing numerical control machine tool retarder generally adopts worm type of reduction gearing, traditional structural design is all adopted in the worm and gear driving section, promptly adopt the integrated type worm screw, such structure can't guarantee the highi degree of accuracy transmission of numerical control machine tool, this be because: 1, under the certain situation of the centre distance of worm and gear, because the manufacturing of worm gear, worm screw adds and has error (comprising diameter dimension error and tooth surface shape size error) man-hour, will cause the worm and gear drive gap, this gap is general＞0.05mm; 2, along with the use of retarder, the wearing and tearing of the worm and gear flank of tooth can cause that also drive gap becomes big.Because retarder when work worm and gear engagement inter-lobe clearance can not be revised, and has influenced the retarder transmission accuracy, and then the machining accuracy when having influenced the numerical control machine tool processed product, quality of product reduced.
Three, summary of the invention
The objective of the invention is to overcome above-mentioned defective, the numerical control machine high accurate speed reducer of the drive gap of a kind of energy modifying factor worm and gear foozle and service wear generation is provided.
For realizing above purpose, numerical control machine high accurate speed reducer of the present invention comprises support, worm gear and worm screw, this worm screw is the combined type worm screw, it is that helix of cylindrical worm radially is divided into two sections at length direction 1/2 place along worm screw, one section band worm shaft, another section is a worm set, and worm set is assemblied on the worm shaft.
After high-accuracy combination processing, make the helix of cylindrical worm of segmentation be combined into high-accuracy one, fully guaranteed the highi degree of accuracy transmission of retarder.Use condition according to retarder, carry out fine finishing by junction plane to two sections of worm screws, revise even eliminate because the drive gap that the foozle of worm and gear and use wearing and tearing cause, the drive gap of worm and gear is controlled in the 0.005mm, fully guaranteed the high transmission accuracy of retarder, accuracy of manufacturing and quality of product when having improved the numerical control machine tool processed product have fundamentally solved traditional worm type of reduction gearing can not guarantee to influence the numerical control machine tool machining accuracy because of transmission accuracy problem.
Numerical control machine high accurate speed reducer compact structure of the present invention, simple, reasonable, volume is little, the Location accuracy height, stable drive, noise free is easy to loading and unloading, is convenient to promote.
Four, description of drawings
Fig. 1 is a numerical control machine high accurate speed reducer plan view of the present invention;
Fig. 2 is a retarder combined type worm screw assembling schematic representation.
Five, embodiment
As shown in Figure 1, 2, numerical control machine high accurate speed reducer of the present invention mainly is made up of parts such as support 1, worm gear 2 and worm screws 3.This worm screw 3 is combined type worm screws, is about to helix of cylindrical worm and radially is divided into two sections along worm screw at length direction 1/2 place, and one section band worm shaft 3-1, another section is worm set 3-2, worm set 3-2 is assemblied on the worm shaft 3-1.When worm screw 3 and worm gear 2 cause that owing to foozle and transmission tooth surface abrasion produces bigger drive gap, by worm screw two junction 3-1.1,3-2.1 are carried out fine finishing, the drive gap of worm screw 3 with worm gear 2 can be adjusted in the 0.005mm, guarantee the highi degree of accuracy transmission of worm and gear.
