Description
Technical field
The utility model relates to retarder, and it is speed reducer dedicated to be specifically related to a kind of lathe.
Background technique
At present moving pillar plane milling and boring machine is to use machining large equipment very widely because stationary table do not move on the ground, so worktable to bear the weight of workpiece unrestricted.But in order to guarantee machining accuracy, moving of crossbeam and two columns must be synchronously.Therefore, must adopt two retarders, and all adopt the spur gear transmission speed reducer usually, because always there is the gap in the spur gear transmission, therefore two columns is mobile always asynchronous, just causes machining accuracy inaccurate.
The model utility content
The purpose of the utility model is to overcome the defective that exists in the existing technology, provide a kind of can eliminate drive gap and improve the lathe of machining accuracy speed reducer dedicated.
For realizing above-mentioned purpose; The technological scheme of the utility model is that a kind of lathe of design is speed reducer dedicated, comprises casing, has input shaft, transition axis, first output shaft and second output shaft in the casing; Be fitted with driving gear on the input shaft; First transition gear of load is in transmission connection on driving gear and the transition axis, also is fitted with second transition gear and the 3rd transition gear on the transition axis, and first of the load input gear transmission is connected on second transition gear and first output shaft; Second of the load input gear transmission is connected on the 3rd transition gear and second output shaft; And the output terminal of first output shaft and second output shaft has first output gear and second output gear respectively, it is characterized in that
A, said driving gear, first transition gear, second transition gear, the 3rd transition gear, the first input gear, the second input gear are spiral gear;
The outer end of b, said transition axis is fitted with bearing pin, is set with anti-backlash on the bearing pin, is fixed with end cap on the casing, and an end of bearing pin stretches out from the center hole of end cap;
C, said input shaft, first output shaft and second output shaft are hollow shaft, on the inwall of said hollow shaft, are provided with spline.
Wherein, on said bearing pin, be provided with radially boss, be provided with overhanging mounting end, on said mounting end, be set with anti-backlash in the outside of said radially boss.
The two end part of said input shaft, transition axis, first output shaft and second output shaft all adopt thrust-bearing to be installed on the casing.
Described anti-backlash is dish-shaped anti-backlash.
The advantage and the beneficial effect of the utility model are: after this retarder adopts said structure, owing to driving gear, first transition gear, second transition gear, the 3rd transition gear, the first input gear, the second input gear are spiral gear; Outer end at said transition axis is fitted with bearing pin, is set with anti-backlash on the bearing pin, and end cap is fixed on the casing, and an end of bearing pin stretches out from the center hole of end cap; If the gap appears in transmission between the gear, can be under the yellow effect of the crack bullet of disappearing, and through adopting spiral gear to cooperate between the gear; Reach the purpose of eliminating drive gap; Thereby improved the transmission accuracy between the gear, made moving of two columns more synchronous, improved machining accuracy.
Description of drawings
Fig. 1 is the speed reducer dedicated structural representation of the utility model lathe.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technological scheme of the utility model, and can not limit the protection domain of the utility model with this.
As shown in Figure 1; The utility model is that a kind of lathe is speed reducer dedicated; Comprise casing 1; Have input shaft 2, transition axis 4, first output shaft 8 and second output shaft 10 in the casing 1; Be fitted with driving gear 3 on the input shaft 2, first transition gear 5 of load is in transmission connection on driving gear 3 and the transition axis 4, also is fitted with second transition gear 6 and the 3rd transition gear 7 on the transition axis 4; First of the load input gear 9 is in transmission connection on second transition gear 6 and first output shaft 8; Second of the load input gear 11 is in transmission connection on the 3rd transition gear 7 and second output shaft 10, and the output terminal of first output shaft 8 and second output shaft 10 has first output gear 12 and second output gear 13 respectively, and said driving gear 3, first transition gear 5, second transition gear 6, the 3rd transition gear 7, first are imported gear 9, second and imported gear 11 and be spiral gear; The outer end of said transition axis 4 is fitted with bearing pin 16, is set with anti-backlash 14 on the bearing pin 16, is fixed with end cap 15 on the casing 1, and an end of bearing pin 16 stretches out from the center hole of end cap 15.Said input shaft, first output shaft and second output shaft are hollow shaft, on the inwall of said hollow shaft, are provided with spline.
As shown in Figure 1, in order to eliminate the gap between the gear transmission more effectively, on said bearing pin 16, be provided with radially boss 16～1, have overhanging mounting end 16～2 in the outside of boss 16～1 radially, be set with anti-backlash 14 on the mounting end 16～2.
As shown in Figure 1, in order to make stable drive, the two end part of said input shaft 2, transition axis 4, first output shaft 8 and second output shaft 9 all adopt thrust-bearing to install.
