One, technical field
The utility model relates to a kind of switch type machine power speed change gear, belongs to machine power speed change gear technical field of structures.
Two, background technique
At present, power speed changing equipment adopts gear type or Worm-gear type to carry out speed change mostly, when needs change sense of rotation, makes the need reversing rotation of motors of power source of motor, but frequent actuating motor is all influential for the life-span of whole electrical network and motor.Can only will not change the outputting power direction with under the situation of internal-combustion engine if do not possess the motor of use at some, just trouble is difficult more.
Three, summary of the invention
The purpose of this utility model is to solve the deficiency that above-mentioned prior art exists, provide a kind of rational in infrastructure, realize outputting power break-in, speed change under the prerequisite of power source sense of rotation need not to change, this machine power speed change gear can be applicable to building, exploration and automobile industry.
The utility model is achieved through the following technical solutions:
A kind of switch type machine power speed change gear, special way is to comprise equipped mutually casing 8 and box back 19, main shaft 28 that crosses casing middle part and the countershaft 27 parallel with main shaft 28, main shaft 28 and casing 8, cover 5 clutch shaft bearing 4 with having clutch shaft bearing respectively between the box back 19, second bearing 17 that has second bearing cap 15 connects, be provided with B belt pulley 3 on the main shaft successively, A Brake drum 6, gear ring 23, sun gear 20 and C belt pulley 16, sun gear 20 and first planet wheel 12 that is installed on the planet carrier 11,21 interlocks of second planet wheel, first planet wheel 12, second planet wheel 21 respectively with gear ring 23 interlocks, the housing two ends of gear ring 23 are respectively equipped with the 3rd bearing 9, the 4th bearing 14, B Brake drum 18, B gear 10, B gear 10 be loaded on countershaft 27 on A gear 24 interlock mutually, also be provided with the 5th bearing 2 on the countershaft 27, the 6th bearing 25 and A belt pulley 1.
Said B Brake drum 18 links with the brake pushrod 13 that can apply braking force.
Said A Brake drum 6 links with braking device 7.
The said braking force that applies is Pneumatic pressure power or hydraulic power.
The working principle of switch type machine power speed change gear:
When B belt pulley 3 during as power intake, apply braking force for B Brake drum 18, at this time gear ring 23 is braked, because planet carrier 11 " number of teeth " is many, output wheel C belt pulley 16 will have the raising speed effect; Conversely, when C belt pulley 16 during as input, B belt pulley 3 output of will slowing down.
If remove the braking action of B Brake drum 18, apply braking force for A Brake drum 6, when the 16 conduct inputs of C belt pulley, A belt pulley 1 has decelerating effect, and the outputting power direction is opposite simultaneously; Otherwise when A belt pulley 1 during as input end, C belt pulley 16 has the speedup effect, and the outputting power direction is opposite.
The utility model has the advantages that rational in infrastructurely, apply the position and can change the outputting power direction, and outputting power speed change, break-in are convenient, flexible, applied widely, long service life by changing the braking source.
