Abstract
The invention discloses a compact type high-speed reversing device comprising a reversing device body, wherein the reversing device body is provided with an arc-shaped circular rolling path with a cambered surface, a ridge and a positioning head. The arc-shaped circular rolling path with the cambered surface consists of a left guide lip, a right guide lip and a rear guide lip. An outlet of the arc-shaped circular rolling path with the cambered surface is arranged on the lower end face of the reversing device body; an air leakage channel is arranged on the upper end face of the reversing device body; and saw teeth are arranged at one side of the positioning head. The compact type high-speed reversing device disclosed by invention has the advantages that a rolling ball is short in rolling flow in a rolling path and rolls smoothly, the movement speed can be increased, the structure is compact, the radial size is small, and the working effect is good.
Description
Technical field
The present invention relates to the back device, relate in particular to a kind of compact type high speed back device, belong to the ball screw pair transmission field.
Background technique
The back device that " the two back device ball-recirculation lead screw pair " of existing a kind of patent No. ZL201020113282.3 selected for use; The back device of this type is that lateral means is in the ball nut entrance end; Because the radial dimension of back device is big, causes the feed screw nut radial dimension bigger; Owing to the raceway long flow path, influenced the fluency and the high speed transmission performance of ball in addition.Therefore, need provide a kind of new technological scheme to solve above-mentioned technical problem.
Summary of the invention
The purpose of this invention is to provide the compact type high speed back device that a kind of fluency is good, high speed and precision is located transmission.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of compact type high speed back device; Comprise back device body; Said back device body is provided with cambered surface arc circulation raceway, back and positioning head, and said cambered surface arc circulation raceway is made up of left guide lip, right guide lip and back guide lip, and the lower end surface of said back device body is provided with the outlet of cambered surface arc circulation raceway; The upper-end surface of said back device body is provided with disappointing passage, and the first side in said location is provided with sawtooth.
Said back is the semicolumn bodily form on the longitudinal direction of back device body.
Said positioning head is the semicircle capitiform.
The invention has the beneficial effects as follows: ball rolls in cambered surface arc circulation raceway, short, the smoothness of rolling of flow process, useful raising movement velocity; The semicylinder axial device of back is in the ball nut both ends of the surface, compact structure, and radial dimension is little; Positioning head places the feed screw nut two ends, and its good working effect is arranged radially, axial two-way positioning action.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
