Abstract
The utility model provides a nut rotary driving mechanism, it relates to drive arrangement technical field, concretely relates to nut rotary driving mechanism. The two ends of the lead screw (6) are provided with a first supporting end (1) and a second supporting end (7), cushion pads (2) are arranged on the inner sides of the first supporting end (1) and the second supporting end (7), the middle of the lead screw (6) is screwed with a lead screw nut (3), a transmission belt wheel (4) is arranged on the rear side of the lead screw nut (3), the transmission belt wheel (4) is connected with a nut sleeve (11), a bearing (9) and a shaft sleeve (10) are arranged on the outer side of the nut sleeve (11), a connecting seat (5) is arranged on the outer sides of the bearing (9) and the shaft sleeve (10), and a transparent cover (8) is arranged on the rear side of the connecting seat. The upper limit of the rotating speed of the ball screw is improved, the running speed of the machine is increased, and therefore the production efficiency of the machine is improved.
Description
Technical field:
The utility model relates to technical field of driving, is specifically related to a kind of nut rotary drive mechanism.
Background technology:
The tradition ball screw kind of drive adopts the rotation of motor-driven leading screw, and the nut on the leading screw drives operating mechanism and moves.Under the condition of big stroke, high speed, leading screw produces shake, thereby has limited the raising of machine speed.
The utility model content:
The purpose of the utility model provides a kind of nut rotary drive mechanism, and it has improved the upper limit of the rotating speed of ball screw, improves machine operating speed, thereby improves the production efficiency of machine.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises first supported end 1, cushion pad 2, feed screw nut 3, drive pulley 4, Connection Block 5, leading screw 6, second supported end 7, covers 8 thoroughly, bearing 9, axle sleeve 10, nut sleeve 11 and driving-belt 12; The two ends of leading screw 6 are provided with first supported end 1 and second supported end 7; First supported end 1 and second supported end, 7 inboards are provided with cushion pad 2, and leading screw 6 middle parts are connected with feed screw nut 3, and the rear side of feed screw nut 3 is provided with drive pulley 4; Drive pulley 4 is connected with nut sleeve 11; Nut sleeve 11 arranged outside have bearing 9 and axle sleeve 10, and the arranged outside of bearing 9 and axle sleeve 10 has Connection Block 5, and the rear side of Connection Block 5 is provided with and covers 8.
Motor is accepted the movement instruction rotation, drives drive pulley 4 rotations, drives feed screw nut 3 rotations, thereby realizes moving of Connection Block.The functional part of equipment links to each other with Connection Block 5.During the feed screw nut rotation, nut sleeve is rotation simultaneously also.Outer ring through bearing 9 is with axle sleeve 10, cover 8 be connected thoroughly, and Connection Block 5 moves with feed screw nut.
The utility model has improved the upper limit of the rotating speed of ball screw, improves machine operating speed, thereby improves the production efficiency of machine.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
Referring to Fig. 1, this specific embodiment is to adopt following technical scheme: it comprises first supported end 1, cushion pad 2, feed screw nut 3, drive pulley 4, Connection Block 5, leading screw 6, second supported end 7, covers 8 thoroughly, bearing 9, axle sleeve 10, nut sleeve 11 and driving-belt 12; The two ends of leading screw 6 are provided with first supported end 1 and second supported end 7; First supported end 1 and second supported end, 7 inboards are provided with cushion pad 2, and leading screw 6 middle parts are connected with feed screw nut 3, and the rear side of feed screw nut 3 is provided with drive pulley 4; Drive pulley 4 is connected with nut sleeve 11; Nut sleeve 11 arranged outside have bearing 9 and axle sleeve 10, and the arranged outside of bearing 9 and axle sleeve 10 has Connection Block 5, and the rear side of Connection Block 5 is provided with and covers 8.
Motor is accepted the movement instruction rotation, drives drive pulley 4 rotations, drives feed screw nut 3 rotations, thereby realizes moving of Connection Block.The functional part of equipment links to each other with Connection Block 5.During the feed screw nut rotation, nut sleeve is rotation simultaneously also.Outer ring through bearing 9 is with axle sleeve 10, cover 8 be connected thoroughly, and Connection Block 5 moves with feed screw nut.
This specific embodiment has improved the upper limit of the rotating speed of ball screw, improves machine operating speed, thereby improves the production efficiency of machine.
