Description
Technical field
The utility model relates to a kind of field of machining, is specifically related to a kind of speed box for lathe.
Background technique
Along with developing rapidly of China's machinery industry, machining requires more and more higher to the quality of equipment, precision etc., and lathe is as the topmost machining equipment of China, and the indices of lathe is required just to seem more and more important.Gearbox is as the topmost constituent element of lathe, and the indexs such as machining accuracy of lathe are played to vital effect.Existing speed box for lathe mainly is comprised of component such as casing, input shaft, output shaft, driving gears, realizes that by the switching driving gear gear ratio of input and output is regulated.But above-mentioned gearbox is in switching during driving gear, the separation end section between gear and less in conjunction with initial segment contact position area, mechanical deterioration very easily appears in gear, affects the working life of gear.
Summary of the invention
The utility model provides a kind of speed box for lathe, and its purpose is to overcome between the gear that speed box for lathe occurs when the switching driving gear in the mechanical deterioration of separating the end section and occurring in conjunction with initial segment, extends the working life of gear.
For achieving the above object, the utility model adopts following technological scheme:
A kind of speed box for lathe, comprise casing, be installed on input shaft and output shaft in casing, it is characterized in that: fixed gear has been fixedly connected respectively on input shaft and output shaft, with the coaxial free gear connected of fixed gear, free gear at least is comprised of 3 arcuation gear masses, the arcuation gear mass connects with input shaft or the output shaft at place by spline, and fixed gear and free gear are selected an engagement.
Further, also comprise shifting block, shifting block connects with the handle on being located at casing by linkage mechanism.
Further, offer radiation hole on casing.
The beneficial effects of the utility model are:
1, be respectively equipped with the free gear at least formed by 3 arcuation gear masses on input shaft and output shaft, when the switching driving gear, first stir the arcuation gear mass that has neither part nor lot in engagement, turn over after several angle the arcuation gear mass of stirring again other on axle, realize the switching of driving gear, in the separation end section of gear and the mechanical deterioration occurred in conjunction with initial segment, extend the working life of gear while having reduced the switching driving gear.
2, casing is provided with handle, and handle connects with the shifting block of stirring the arcuation gear mass by linkage mechanism, facilitates stirring of arcuation gear mass, and the switching driving gear is convenient, fast
3, offer radiation hole on casing, effectively lower the temperature in casing, improve the utilization efficiency of gearbox.
The accompanying drawing explanation
Fig. 1 is assembling schematic diagram of the present utility model;
Fig. 2 is free gear and splined schematic diagram in the utility model;
Wherein reference character is: 1-casing, 2-input shaft, 3-output shaft, 4-fixed gear, 5-free gear, 6-arcuation gear mass, 7-spline, 8-radiation hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As depicted in figs. 1 and 2, lathe gearbox, comprise casing 1, input shaft 2 and output shaft 3 are arranged in casing 1 by bearing, be separately installed with driving gear on input shaft 2 and output shaft 3, input shaft 2 passes to output shaft 3 by power by driving gear, and finally drives the machine tool chief axis rotation.Described driving gear comprises fixed gear 4 and free gear 5, on input shaft 2, is coaxially installed with fixed gear 4 and free gear 5, is coaxially installed with equally fixed gear 4 and free gear 5 on output shaft 3.Fixed gear 4 is fixedly connected on input shaft 2 or output shaft 3 by flat key, free gear 5 connects with input shaft 2 or the output shaft 3 at its place by spline 7, this free gear 5 is spliced by least 3 arcuation gear masses 6, each arcuation gear mass 6 not only can not come off from input shaft 2 or output shaft 3, and can axially move along spline 7, realize the switching of driving gear.Under working state, fixed gear 4 and free gear 5 is two pairs of gears that switch between engagement and separated state one to one, and two pairs of gears are selected an engagement.Be provided with one handle on casing 1 outer surface, this handle connects with the shifting block in casing 1 by linkage mechanism.Pull handle, move through linkage mechanism and pass to shifting block, shifting block is stirred 6 axial motions of arcuation gear mass, realizes the switching of driving gear.While working due to gearbox, the high-speed gear rotation, produce a large amount of heats, therefore, on casing 1 surface, offers radiation hole 8, by radiation hole 8, distributes the heat that casing 1 internal gear produces, for the gear normal operation provides better condition.
Under working state, be arranged on respectively fixed gear 4 on input shaft 2 and output shaft 3 and free gear 5 for one to one two pairs in engagement the gears with the switching of separated state part, two pairs of gears are selected an engagement, during i.e. free gear 5 engagement in fixed gear in input shaft 24 and output shaft 3, free gear 5 in input shaft 2 and the fixed gear 4 in output shaft 3 are in non-engagement state, on the contrary also establishment.When the needs change gear, first by the shifting block connected with handle, axially push away the arcuation gear mass 6 of the non-engagement side of in/out position, now arcuation gear mass 6 axially moves to certain position, input/shaft rotates to an angle afterwards, axially push away again the now arcuation gear mass in non-engagement side position of in/out, repeat above-mentioned action, until the free gear 5 in engagement exited engagement fully originally, originally the free gear in non-engagement state is fully in engagement, the release of above-mentioned arcuation gear mass and push and can carry out simultaneously.Because free gear 5 of the present utility model is comprised of at least 3 arcuation gear masses 6, therefore, even if occur in same free gear 5 that two arcuation gear masses 6 are in engagement simultaneously, also other arcuation gear mass 6 axially can be pushed away to in/out, but while by 2 arcuation gear masses 6, forming the movable teeth wheel body, two 6 whiles of arcuation gear mass, when engagement, push away in/out arcuation gear mass 6 just particularly difficult.
Due to two pairs of gears (as shown in Figure 1) only being installed on above-mentioned input shaft 2 and output shaft 3, by the number of teeth of setting each gear, can only realize two gear ratio.In order to realize more, larger gear ratio, can on the basis of Fig. 1, separately establish respectively again the free gear 5 that quantity is equal on input shaft 2 or output shaft 3; Also can set up transmission shaft, fixed gear 4 and free gear 5 are installed on this transmission shaft accordingly, multipair fixed gear 4 and free gear 5 are realized more, larger gear ratio in the mode of selecting an engagement one to one, meet process requirements.
Fixed gear 4 in above-mentioned driving gear and free gear 5, except adopting straight-tooth, angular gear, also can adopt bevel gear, and its working principle is identical with foregoing with handoff procedure.In the specific implementation, can meet different process requirements by the angle of regulating between input shaft 2 and output shaft 3.
