Abstract
The utility model relates to a speedup type mining gearbox. The gearbox comprises a three-shift gear, a three-shift shaft, a single-shift shaft, a single-shift gear, an output shaft and an output gear. The three-shift shaft is fixedly connected to the three-shift gear. The single-shift shaft is fixedly connected to the single-shift gear. The output shaft is fixedly connected to the output gear. The output gear is engaged to the single-shift gear. The gearbox further comprises a speedup gear that sleeves the single-shift gear and is fixedly connected to the single-shift gear. The speedup gear is engaged to the three-shift gear. The number of teeth of the speedup gear is less than the number of teeth of the three-shift gear. The number of teeth of the output gear is less than the number of teeth of the three-shift gear. The gearbox overcomes problems that the conventional gearbox fails to speed up to lead to motor power to be not fully utilized. The gearbox is additionally provided with the speedup gear on the basis of the gearbox with compact structure, so that the requirements of the mining engineering machinery are better met, and the wide speedup scope largely meets the requirements of economic efficiency and productivity of the mining industry and engineering machinery.
Description
Technical field
The utility model relates to a kind of actuating unit, is exactly a kind of acceleration type gear box for mine specifically.
Background technique
Existing gearbox designs is compact, spacing between one gear shaft and output shaft and three gear shafts and output shaft differs very little, therefore causes three gear gears identical with the number of teeth of output gear, and three gear shaft speed are passed to output shaft through a gear shaft, speed does not change, cannot speedup.Even also all cannot speedup travel the in the situation that of making that vehicle is good in road conditions, vehicle is unloaded etc., the power of motor does not just make full use of like this, causes energy loss larger.
Model utility content
Cannot speedup in order to solve existing gearbox, the technical problem that causes engine power not make full use of, the utility model provides a kind of acceleration type gear box for mine.
Technical solution of the present utility model:
Acceleration type gear box for mine, comprise three gear gears, three gear shafts, a gear shaft, first gear, output shaft, output gear, described three gear shafts are fixedly connected with three gear gears, a described gear shaft is fixedly connected with first gear, described output shaft is fixedly connected with output gear, described output gear and first gear are intermeshing
Its special way is: also comprise overdrive gear, described overdrive gear is sleeved on a gear shaft and with it and is fixedly connected with, described overdrive gear engages with three gear gears, and the number of teeth of described overdrive gear is less than the number of teeth of three gear gears, and the number of teeth of described output gear is less than the number of teeth of three gear gears.
The utility model has advantages of:
1, on the gearbox of compact structure, increase overdrive gear, met better the needs of mining engineering machinery, wide in range slewing range has met mining industry widely, the Economy of engineering machinery and productivity requirement.
2, the utility model, under the structure prerequisite that does not change gearbox, reaches the effect of speedup, simple in structure, convenient realization.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model acceleration type gear box for mine;
Wherein reference character is: 1-tri-keeps off gear, 2-tri-gear shafts, 3-overdrive gear, 4-mono-gear shaft, 5-first gear, 6-output shaft, 7-output gear.
Specifically mode of execution
As shown in Figure 1, acceleration type gear box for mine, comprise three gear gears 1, three gear shafts 2, one gear shaft 4, first gear 5, output shaft 6, output gear 7, three gear shafts 2 are fixedly connected with three gear gears 1, one gear shaft 4 is fixedly connected with first gear 5, output shaft 6 is fixedly connected with output gear 7, output gear 7 is intermeshing with first gear 5, also comprise overdrive gear 3, overdrive gear 3 is sleeved on a gear shaft 4 and with it and is fixedly connected with, overdrive gear 3 engages with three gear gears 1, the number of teeth of overdrive gear 3 is less than the number of teeth of three gear gears 1, the number of teeth of output gear 7 is less than the number of teeth of three gear gears 1.
Speedup principle of the present utility model:
On a gear shaft of gearbox, design an overdrive gear, thereby solved the design difficulty of the difference increase of the three gear gear numbers of teeth and the output gear number of teeth, captured the difficulty of gearbox speedup gear design.In the time of transmission of power to three gear shaft, three gear gears rotate with it, and the overdrive gear engaging with three gear gears also rotates thereupon, and drives first gear to rotate, and first gear drives the output gear being engaged with to rotate.Because the number of teeth of overdrive gear is less than three gear gears, the number of teeth of output gear is less than the number of teeth of three gear gears, realizes speedup.
Claims (2)
1. acceleration type gear box for mine, comprise three gear gears, three gear shafts, a gear shaft, first gear, output shaft, output gear, described three gear shafts are fixedly connected with three gear gears, a described gear shaft is fixedly connected with first gear, described output shaft is fixedly connected with output gear, described output gear and first gear are intermeshing
It is characterized in that: also comprise overdrive gear, described overdrive gear is sleeved on a gear shaft and with it and is fixedly connected with, described overdrive gear engages with three gear gears, and the number of teeth of described overdrive gear is less than the number of teeth of three gear gears.
2. acceleration type gear box for mine according to claim 1, is characterized in that: the number of teeth of described output gear is less than the number of teeth of three gear gears.
