Abstract
The invention discloses a transmission gear sliding device which comprises a gear regulation shaft, a moving shaft, a spring, a shift key and a working shaft, wherein the gear regulation shaft is perpendicular to the moving shaft, and is meshed with the moving shaft; the spring and the shift key are connected with the moving shaft through elastic cylindrical pins, and are embedded into a slot of the moving shaft; one end of the spring is clamped in a pit in the end part of the slot of the moving shaft, and the other end of the spring is clamped on the lower surface of the shift key; the end, with the slot, of the moving shaft is sleeved by a hole of the working shaft; a slot is also cut in the working shaft, and is opposite to the slot of the moving shaft; when the working shaft rotates, gears rotate along with the working shaft, and when different gears are required to work, the gear regulation shaft can be rotated to drive the moving shaft to move to different positions to mesh the shift key with different gears. The transmission gear sliding device is simple in structure and simple and convenient to operate, the shift key can be conveniently regulated to realize the meshing transmission of different gears, and the shortcoming of high damage rate of gear teeth during the position regulation of the sliding gears is overcome.
Description
Technical field
The present invention relates to machine tool transmission system technical field, particularly relate to a kind of driving gear slide device.
Background technique
In existing machine tool transmission system, when needing to realize different drive ratios, the different gears meshing of many employings realizes, what mechanically generally adopt is on axle, install the shifting slide gear can doing to move axially along axle realize, when adjusting the position of shifting slide gear, many employings shift fork promotes to make different gear enter engagement, now than the collision being easier to cause between the gear teeth, the gear teeth easily damage, traditional shifting slide gear needs to pull shift fork when regulating and realizes different gear teeth meshing, troublesome poeration, in order to improve this situation, design a kind of driving gear slide device and seem very necessary.
Summary of the invention
When object of the present invention is exactly the position in order to overcome prior art adjustment shifting slide gear, the gear teeth are easily caused to damage, the defect of troublesome poeration, devise a kind of driving gear slide device, adopt and regulate the position of shift key to make different meshed gears in running order, the defect that when avoiding the position of adjustment shifting slide gear, the gear teeth easily damage.
The required technical problem solved of the present invention can be achieved through the following technical solutions:
A kind of driving gear slide device, comprise regulating tooth wheel shaft, shifting axle, spring, shift key, working shaft, the front end of described regulating tooth wheel shaft is adjusting gear, described regulating tooth wheel shaft and described shifting axle are arranged vertically, described spring and described shift key all adopt elastic cylindrical pin to be connected with described shifting axle, be drilled with cylindrical hole in the middle of described working shaft, namely one end of described shifting axle is enclosed within the hole of described working shaft.
The half circle of described shifting axle cuts spiral-shaped teeth, has engaged with adjusting gear.
Upper half part of described shifting axle has cut an elongated slot vertically.
Described spring and shift key are all embedded in the groove of shifting axle upper half part, and one end of spring is stuck in the pit of shifting axle trough end, and the other end is stuck in the lower surface of shift key.
The shaft part that described working shaft installs gear has also cut an elongated slot.
Trough on described shifting axle on the direction of trough and working shaft is just right.
The height of described shift key exceeds the trough certain altitude of working shaft, and its projection just embeds in the keyway of gear.
Owing to have employed above technological scheme, tool of the present invention has the following advantages:
Adopt the Combination Design of regulating tooth wheel shaft, shifting axle, spring, shift key, working shaft, regulate the position of shift key that different meshed gears can be made in running order, the collision between the gear teeth is easily caused when avoiding the position of adjustment shifting slide gear, the defect that the gear teeth easily damage, regulate during the position of shift key and only need rotate regulating tooth wheel shaft, avoid traditional shifting slide gear to need to pull the trouble that shift fork realizes different gear teeth meshing when regulating, easy and simple to handle.
Accompanying drawing explanation
Fig. 1 is structural blast figure of the present invention;
In figure, each label implication is:
1, regulating tooth wheel shaft; 2, spring; 3, shift key; 4, working shaft; 5, elastic cylindrical pin; 6, gear; 7, shifting axle.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
A kind of driving gear slide device, comprise regulating tooth wheel shaft 1, shifting axle 7, spring 2, shift key 3, working shaft 4, the front end of regulating tooth wheel shaft 1 is adjusting gear, cylindrical hole is drilled with in the middle of working shaft 4, during work, rotate regulating tooth wheel shaft 1, due to the gear teeth meshing of adjusting gear and shifting axle 7 end, promote shifting axle 7 to move axially in the hole of working shaft 4, when shift key 3 moves to working shaft 4 trough position, the elastic force of spring 2 promotes shift key 3 and slips into this groove, and it highly exceeds trough certain altitude, the projection of shift key 3 just embeds in the keyway of gear 6, when then working shaft 4 rotates, gear 6 plays rotation with one, when needing different working gears, then shifting axle 7 can be driven to move to diverse location by rotating regulating tooth wheel shaft 1, shift key 3 is realized from different gears meshing.
The half circle of shifting axle 7 has cut spiral-shaped teeth, and regulating tooth wheel shaft 1 and shifting axle 7 are arranged vertically, and the tooth between them engages each other.
Upper half part of shifting axle 7 has cut an elongated slot vertically.
Spring 2 and shift key 3 all adopt elastic cylindrical pin 5 to be connected with shifting axle 7, and embed in the groove of shifting axle 7 upper half part, one end of spring 2 is stuck in the pit of shifting axle 7 trough end, and the other end is stuck in the lower surface of shift key 3.
The shaft part installing gear 6 at working shaft has also cut an elongated slot.
Namely one end that shifting axle 7 cuts trough is enclosed within the hole of working shaft 4, on it direction of trough and the trough of working shaft 4 just right.
Structure of the present invention is simple, regulate the position of shift key 3 that different meshed gears can be made in running order, the collision between the gear teeth is easily caused when avoiding the position of adjustment shifting slide gear, the defect that the gear teeth easily damage, regulate during the position of shift key 3 and only need rotate regulating tooth wheel shaft 1, avoid traditional shifting slide gear to need to pull the trouble that shift fork realizes different gear teeth meshing when regulating, easy and simple to handle
