Abstract
The utility model discloses a compact high-speed reversing device, which comprises a reversing device main body. The reversing device main body is provided with a cambered surface arc-shaped circular rollway, a backbone, and a positioning head. The cambered surface arc-shaped circular rollway is composed of a left guide lip, a right guide lip and a rear guide lip; and the lower end surface of the reversing device main body is provided with a cambered surface arc-shaped circular rollway outlet, and the upper end surface thereof is provided with a gas release channel, and one side of the positioning head is provided with sawteeth. The compact high-speed reversing device disclosed by the utility model has the following advantages: the rolling route of a ball in the rollway is short, and the rolling of the ball is smooth, so as to facilitate the increase of the movement speed; and the structure is compact, the radial dimension is small, and the working effect is good.
Description
Technical field
The utility model relates to the back device, relates in particular to a kind of compact type high speed back device, belongs 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.
The model utility content
The purpose of the utility model provides the compact type high speed back device that a kind of fluency is good, high speed and precision is located transmission.
The utility model solves the technological scheme that its technical problem adopted:
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 beneficial effect of the utility model is: 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 utility model is described further.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the rear view of the utility model.
Wherein: 1, positioning head, 2, left guide lip, 3, right guide lip, 4, the lower end surface; 5, back, 6, the back guide lip, 7, sawtooth, 8, the upper-end surface; 9, the passage that loses heart, 10, back device body, 11, cambered surface arc circulation raceway, 12, the outlet of cambered surface arc circulation raceway.
Embodiment
As illustrated in fig. 1 and 2; A kind of compact type high speed back device of the utility model; Comprise back device body 10, back device body 10 is provided with cambered surface arc circulation raceway 11, back 5 and is the positioning head 1 of semicircle capitiform, and back 5 is the semicolumn bodily form on the longitudinal direction of back device body 10; Cambered surface arc circulation raceway 11 is made up of left guide lip 2, right guide lip 3 and back guide lip 3; The lower end surface 4 of back device body 1 is provided with cambered surface arc circulation raceway outlet 12, and the upper-end surface 8 of back device body 10 is provided with the passage 9 that loses heart, and positioning head 1 one sides are provided with sawtooth 7.
This compact type high speed back device is made filler with metal powder material, and sintering forms behind the disposable die cast.
Ball rolls in cambered surface arc circulation raceway 11, short, the smoothness of rolling of flow process, useful raising movement velocity; The semicylinder axial device of back 5 is in the ball nut both ends of the surface, compact structure, and radial dimension is little; Positioning head 1 places the feed screw nut two ends, and positioning head 1 is the semicircle capitiform, and its good working effect is arranged radially, axial two-way positioning action.
