Abstract

The utility model provides a ball screw gear pair transmission mechanism with nut rotation, which comprises a left support, a right support, a screw, a left anti-collision block, a right anti-collision block, a screw nut, a driving belt wheel, a driving belt, a motor, a nut sleeve, a connecting body, a bearing, a shaft sleeve and an end cover. During the work process, the screw does not rotate; the motor dives the screw nut to rotate through the driving belt wheel; the screw nut axially moves in a straight line along the screw; and the screw nut is connected with the motor through the connecting body, so as to ensure that the motor and the screw nut kept move axially and synchronously along the screw. The nut rotation rather than the screw rotation is adopted in the transmission mechanism so that ball screw gear pair transmission mechanism still has high transmission precision and speed in the situation with long distance and heavy load; the service life of the screw is prolonged.

Description

The ball screw auxiliary drive gear that nut rotates

Technical field

The utility model relates to driving mechanism, the ball screw auxiliary drive gear that particularly a kind of nut rotates.

Background technique

Characteristics such as ball screw pair generally is made up of devices such as nut, leading screw and balls, has the Location accuracy height, and transmission speed is fast have been widely used in the industry that lathe, textile manufacturing machine and seal chartered plane tool etc. require highi degree of accuracy or high efficiency transmission.When leading screw during as active body, the driven by motor leading screw rotates, and nut changes into straight line motion with the rotation angle of leading screw according to the helical pitch of corresponding specification, and workpiece can be fixedlyed connected with nut, the straight line motion of realization.But leading screw under the heavy duty situation of long stroke, is easy to generate bigger scratching during as active body, also can produce distortion, influences the transmission accuracy and the transmission speed of lathe; Simultaneously, also can shorten to some extent the working life of leading screw.

The model utility content

The purpose of this utility model is to overcome the deficiencies in the prior art, the ball screw auxiliary drive gear that provides a kind of nut to rotate, to guarantee the transmission accuracy and the transmission speed of ball screw pair, overcome the radial load of belt simultaneously, improve working life, make it adapt to the heavy duty operating mode of long stroke.

To achieve these goals, the utility model has adopted following technological scheme: the ball screw auxiliary drive gear that a kind of nut rotates comprises left supporting element, right supporting element, leading screw, the anti-collision block in a left side, right anti-collision block, feed screw nut, drive pulley, driving belt, motor, nut sleeve, connecting body, bearing, axle sleeve and end cap; Leading screw is fixedly connected between left supporting element and the right supporting element, anti-collision block in a left side and right anti-collision block are set on the leading screw and are close to the inboard of left supporting element and right supporting element, feed screw nut is connected the centre of leading screw, drive pulley is sleeved on the feed screw nut and with feed screw nut and is fixedly linked, driving belt is connected between drive pulley and the motor, nut sleeve is sleeved on the feed screw nut and with drive pulley and is fixedly linked, bearing and axle sleeve are sleeved on the nut sleeve, one end of connecting body is sleeved on nut sleeve, on bearing and the axle sleeve, the other end and the motor of connecting body are fixedly linked, and end cap is sleeved on the nut sleeve and with connecting body and is fixedly linked.

The ball screw auxiliary drive gear that nut of the present utility model rotates compared with prior art, leading screw distortion and disturbing phenomenon that the ball screw auxiliary driving occurs have been reduced largely in transmission process, reduced the vibration of lathe, under the heavy duty situation of long stroke, still can keep high transmission accuracy and transmission speed, the life-span of having improved leading screw.

Description of drawings

Fig. 1 is the overall structure schematic representation of the ball screw auxiliary drive gear of the utility model nut rotation;

Fig. 2 is the broken section structural representation of the ball screw auxiliary drive gear of the utility model nut rotation.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

Referring to Fig. 1, Fig. 2, the ball screw auxiliary drive gear that nut of the present utility model rotates comprises left supporting element 1, right supporting element 2, leading screw 3, the anti-collision block 4 in a left side, right anti-collision block 5, feed screw nut 6, drive pulley 7, driving belt 8, motor 9, nut sleeve 10, connecting body 11, bearing 12, axle sleeve 13 and end cap 14.Leading screw 3 is fixedly connected between left supporting element 1 and the right supporting element 2, anti-collision block 4 in a left side and right anti-collision block 5 are set on the leading screw 3 and are close to the inboard of left supporting element 1 and right supporting element 2, feed screw nut 6 is connected the centre of leading screw 3, drive pulley 7 is sleeved on the feed screw nut 6 and with feed screw nut 6 and is fixedly linked, driving belt 8 is connected between drive pulley 7 and the motor 9, nut sleeve 10 is sleeved on the feed screw nut 6 and with drive pulley 7 and is fixedly linked, bearing 12 and axle sleeve 13 are sleeved on the nut sleeve 10, one end of connecting body 11 is sleeved on nut sleeve 10, on bearing 12 and the axle sleeve 13, the other end of connecting body 11 and motor 9 are fixedly linked, and end cap 14 is sleeved on the nut sleeve 10 and with connecting body 11 and is fixedly linked.

Working procedure of the present utility model and principle can be described as follows in conjunction with Fig. 1: leading screw 3 two ends are fixing by left supporting element 1 and right supporting element 2, apply pulling force at two support ends during installation, can improve the rigidity of screw mandrel 3, and leading screw 3 distortions and disturbance are reduced; The anti-collision block 4 in a left side of extremity piece inboard is supported on a left side, the anti-collision block 5 in the right side of right supporting element 2 inboards can avoid feed screw nut 6 and supporting element directly to bump against, and plays buffer function; When motor 9 rotates, drive drive pulley 7 by driving belt 8 and rotate, drive pulley 7 drives feed screw nut 6 rotations.Because leading screw 3 is fixed, feed screw nut 6 will be done axial motion along leading screw 3; Drive pulley 7 connects by bolts and nuts cover 10, nut sleeve 10 is installed on connecting body 11 1 end inside by bearing 12, axle sleeve 13 and end cap 14, connecting body 11 the other ends are connected with motor 9, constituted a fixed connection structure, when feed screw nut 63 when leading screw 3 is done axial motion, also will drive motor 9 and axially be synchronized with the movement along leading screw 3.
