Abstract
The invention discloses a ball screw transmission device with the fixed length limiting function. The ball screw transmission device with the fixed length limiting function comprises a lead screw, a lead screw sleeve and balls, wherein a ball bushing is arranged between the lead screw and the lead screw sleeve, the ball bushing is arranged on one segment of the lead screw in a sleeved mode, the movable balls are arranged in the ball bushing in a clamped mode, the balls are arranged on the ball bushing according to the shape of threads of the lead screw in the direction of the threads of the lead screw, limiting nails are arranged at the two ends of the lead screw, and bayonets abutting against the limiting screws are arranged at the two ends of the ball bushing. According to the ball screw transmission device with the fixed length limiting function, through the specially designed ball bushing, the sliding guiding function can be achieved, the stroke of the lead screw sleeve can be limited, the ball bushing is prevented from continuously rotating due to the limiting screws at the preset positions, and therefore the lead screw sleeve can stop linear movement and only idle along the ball bushing.
Description
Technical field
The present invention relates to mechanical transmission, relate in particular to a kind of transmission of carrying out within the scope of certain length, otherwise depart from the spindle gear of transmission.
Background technique
The present invention relates to the spacing ball leading screw driving device of fixed length, general ball leading screw driving device can limited location the function of idle running, be at most because the length of screw mandrel is limit, stop operating to end.And in this case related ball screw, what need to complete is the routine rotation that limits length, reaching while limiting position, screw rod bushing can not can stop operating, and can proceed idle running.
Summary of the invention
The present invention is directed to above problem and proposed to transmit certain power limiting in length, and the ball leading screw driving device that is reaching the laggard line space of this restriction length and turn.
The spacing ball leading screw driving device of fixed length that relates to of the present invention, this ball leading screw driving device comprises screw mandrel, screw rod bushing and ball, it is characterized in that, between screw mandrel and screw rod bushing, be provided with ball bushing, this ball bushing is enclosed within a section of screw mandrel, on it, snap in multiple free balls, the plurality of ball shape along wire rod thread on ball bushing is arranged with moving towards; Be provided with stop screw at screw mandrel two ends, there is the bayonet socket that withstands this stop screw at the two ends of ball bushing.
This bayonet socket is a ladder breach of ball bushing axial direction.
Bearing and gear that the spacing ball leading screw driving device of this fixed length also comprises the erection joint that is fixedly installed togather with screw rod bushing, is installed together with screw mandrel.
The ball bushing that the present invention crosses by a special design, not only can slide guide but also can be screw rod bushing stroke limit, limit ball bushing at default position stop screw and be rotated further, thereby screw rod bushing can only be dallied and stop straight line motion along ball bushing.
[brief description of the drawings]
Fig. 1 is spindle gear structural representation of the present invention;
Fig. 2 is the ball bushing enlarged diagram of spindle gear of the present invention;
Fig. 3 is spindle gear sectional view of the present invention;
Wherein: 10, screw mandrel; 20, screw rod bushing; 30, ball bushing; 31, bayonet socket; 40, ball; 50, stop screw; 60, erection joint; 70, bearing; 80, gear.
[embodiment]
Below in conjunction with drawings and Examples, the spindle gear of fixed length transmission of the present invention is elaborated.
Please refer to accompanying drawing 1: wherein show the spacing ball leading screw driving device of fixed length that relates to of the present invention, this ball leading screw driving device comprises screw mandrel 10, screw rod bushing 20 and ball 40, between screw mandrel 10 and screw rod bushing 20, be provided with ball bushing 30, this ball bushing 30 is enclosed within a section of screw mandrel, on it, snap in multiple free balls 40, the plurality of ball shape along wire rod thread on ball bushing 30 is arranged with moving towards; Be provided with stop screw 50 at screw mandrel 10 two ends, there is the bayonet socket 31 that withstands this stop screw 50 at the two ends of ball bushing 30; This bayonet socket 31 is ladder breach for ball bushing 30 axial directions.In the time of normal rotation, screw rod bushing, along the ball slide guide on ball bushing 30, rotates and moves axially on leading screw, when turn to certain apart from time, when now ball bushing 30 has arrived the position of stop screw 50, its bayonet socket 31 holds out against and is stuck in stop screw place, stops operating.Now, screw rod bushing 20 is rotated further, and only can only dally along ball bushing 30 outer surfaces, moves no longer forward.And when opposite spin, principle is identical, the other one end bayonet socket 31 that is only ball bushing 30 is limited by screw mandrel 10 another one stop screws 50, move no longer forward, and screw set 20 just starts idle running.
Bearing 70 and gear 80 that the spacing ball leading screw driving device of this fixed length also comprises the erection joint 60 that is fixedly installed togather with screw rod bushing 20, is installed together with screw mandrel.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, but not in order to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, when utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be not depart from technical solution of the present invention content, refer to any simple modification that above embodiment is done according to the technology of the present invention, equivalent variations and modification, all belong in the scope of technical solution of the present invention.
