Description

Set composite in rotary moving
Technical field
This utility model relates to technical field of mechanical transmission, particularly relates to a kind of set composite in rotary moving.
Background technology
Rotate and movement is two kinds of basic forms of motion in machine driving.In the prior art, individually rotate, individually Move or be mutually related rotation and mobile being all easier realizes.And some equipment, it is desirable that non-interference rotation And movement.Chinese utility model patent notification number CN 202484239U discloses and a kind of rotates translation composite structure, this mechanism by Runner assembly and translation assembly two parts are constituted, and runner assembly is rotated by motor-driven rotatable shaft, rotary shaft through leading screw through hole with Rotary work-table is fixing to be connected, and rotary shaft drives rotary work-table to rotate;Translation assembly drives worm gear wheel by worm screw, drives Translation workbench moves up and down.So, this structure is achieved that in transmission to meet simultaneously and rotates and translation requirement, and two kinds of fortune Do not interfere between Dong.But, said structure is more complicated, processing difficulties.
Summary of the invention
For solving above-mentioned technical problem, this utility model provides a kind of simple in construction, easy to process in rotary moving compound Device.
The technical scheme in the invention for solving the above technical problem is as follows:
A kind of set composite in rotary moving, including axle, cylindrical rack, dive key, the first gear and installs successively The first lining, the second gear and the second lining on axle, described dive key has certain length and is axially mounted to axle On keyway in;Described second gear is herringbone bear, and it is driven by driving gear and pass through dive key and is connected with axle, drives Axle rotates, and dive key is packed on axle by screw;Can be in axially opposing slip between second gear and axle;Described cylinder Tooth bar is fixedly installed on axle and between described first lining and dive key;Described first gear is driven by driving means Moving and engage with described cylindrical rack, band moving axis moves axially;Described first lining, the second lining are supported by supporting construction, Relative to sliding and can move for support shaft and with between axle.
Above-mentioned cylindrical rack is integrally formed with axle, including cylindrical body and be formed on this cylindrical body multiple Annular tooth, the plurality of annular tooth is parallel to each other and spaced set.
Preferably, described cylindrical rack is identical with described guide flat key length, in order to when axle is axially moveable, Second gear can omnidistance be connected by dive key with axle.
The structure of above-mentioned first lining and the second lining is identical, by body and be arranged between this body and described axle 1 Multiple balls constitute, ball scribbles lubricant grease, to reduce frictional force.
Set composite in rotary moving of the present utility model has the advantage that compared with existing rotating and moving device of configuration-changeable
1, two kinds of forms of motion of mobile rotation can be realized non-interference;
2, use cylindrical rack and dive key connecting mode, make rotation and migration on a component, component Few, simple in construction;
3, the cylindrical rack structure improved is easy to process, and single unit system cost of manufacture is low;
4, axle is supported by two linings.When axle slide or rotate time, its can automatic adjusting position, make at gear drive In minimum drag state.
5, in this structure, the second gear engages with driving gear, and when axle moves axially, the second gear will not move with axle Dynamic.
Accompanying drawing explanation
Fig. 1 is the structural representation of set composite in rotary moving of the present utility model.
Wherein:
1, axle the 2, first lining 3, cylindrical rack 4, dive key
5, screw the 6, second lining the 7, first gear the 8, second gear
Detailed description of the invention
Below in conjunction with the accompanying drawings the structure of set composite in rotary moving of the present utility model is described in detail.
Seeing the set composite in rotary moving of Fig. 1, its core component is axle 1, and axle 1 can carry out non-interference rotation and shifting Dynamic.The concrete structure of this device is as follows:
A kind of set composite in rotary moving, including axle 1, cylindrical rack 3, dive key the 4, first gear 7 and successively The first lining the 2, second gear 8 and the second lining 6 being arranged on axle 1.
Dive key 4 has certain length and is axially mounted in the keyway on axle 1;Second gear 8 is by driving means Driving and pass through dive key 4 and be connected with axle 1, can rotate by band moving axis 1, the second gear 8 is herringbone bear, energy between itself and axle 1 In axially opposing slip.Cylindrical rack 3 is fixedly installed on axle 1 and between the first lining 2 and dive key 4.First Gear 7 is driven by driving means and engages with cylindrical rack 3, and band moving axis 1 moves axially.First lining the 2, second lining 6 Being supported by supporting construction, said two lining for support shaft 1 and relative to sliding and can move with between axle 1.
Cylindrical rack 3 is typically integrally formed with axle 1, and it includes cylindrical body and is formed on this cylindrical body Multiple annular tooth, multiple annular tooth are parallel to each other and spaced set.First gear 7 in rotation process with corresponding annular tooth Engagement, makes axle 1 move.The length of described cylindrical rack 3 and described dive key 4 is preferably identical, in order to move vertically at axle Time dynamic, the second gear 8 can omnidistance be connected by dive key with axle.
First lining 2 is identical with the structure of the second lining 6, by body and be arranged between this body and described axle 1 Multiple balls are constituted.Lubricant grease is scribbled, to reduce frictional force on ball.In the embodiments illustrated in the figures, dive key 4 leads to Cross screw 5 to be packed on axle 1.Multiple balls are zigzag arrangement.
It addition, although figure does not shows, when axle 1 is axially moveable, because the second gear 8 is herringbone bear and driving gear Engagement, so will not move with axle.
During use, driving means, such as motor, drive the second gear 8, thus band moving axis 1 rotates;Meanwhile, Two gears 7 engage with cylindrical rack 3, and under the effect of driving means, band moving axis 1 moves axially, it is achieved the rotation fortune of axle 1 Move and move and carry out simultaneously.When the second gear 8 band moving axis 1 rotates, cylindrical rack 3 can keep nibbling with the first gear 7 all the time Closing, the rotation without countershaft 1 is formed to be interfered;When the first gear 7 band moving axis 1 moves axially, dive key 4 makes the second gear 8 keep being connected with axle 1 all the time, and the mobile formation without countershaft 1 is interfered.And, make dive key 4 due to the rotation of axle 1 Working side surface pressure increase, frictional force is when increasing and affect axle 1 mobile, or due to the movement of axle 1, makes cylinder tooth bar 3 Working side surface pressure increase, frictional force increase and when affecting the rotation of axle 1, due to the supporting of first, second lining 2,6, energy Make axle 1 automatic adjusting position, make gear drive be in minimum drag state.
Outfan at axle 1 connects corresponding device, can realize the rotary motion of this device and being combined of moving axially Motion.
