Description
(1) technical field
The utility model relates to a kind of speed changer.
(2) background technique
No matter in modern industry and the life is steam, gas turbine, generator, diesel engine, still various gas compressors, water pump, oil pump, so that the pass of some valves, the instrument that opens all need different types of speed changer.There is complex structure in various retarders such as a large amount of now gear-shift transmissions that use, turbine worm, harmonic wave, the processing cost height, and weight is big, the big deficiency that waits of volume.For example the gear reducer used of line belt is twice abovely than motor volume, weight, and its cost exceeds 3-5 doubly than the motor of coupling; The used speed increaser of centralized air-conditioning gas compressor than the big 1-2 of volume, weight of drive motor doubly, cost exceeds 5-8 doubly; Application centrifugal, axial-flow compressor also is subjected to the high restriction of speed increaser cost.The speed changer present situation has a strong impact on Development in Machine Industry.
(3) summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, volume and the weight dual-purpose speed changer of ball bearing little, with low cost.The purpose of this utility model is achieved in that it comprises input shaft, output shaft, the end of input shaft is a retainer with holes, in the hole of retainer, steel ball is installed, input shaft, output shaft match the end outer installment outer race is arranged, the outer race surface of matching with steel ball is v shape groove, its v shape angle is 180 °-30 °, drive fit between outer race, output shaft and the steel ball, and the outer race left end is equipped with bearing cap.The utility model can also comprise like this some additional structural features: the hole on (1) retainer is radially straight hole or oblique hole; (2) outer race is made up of two-part, has between two-part between tightness spacer and two-part to be connected by bolt; (3) output shaft and steel ball fitting surface hold the v shape groove or the conical surface of cylndrical surface, peripheral band pouring weight; (4) output shaft and steel ball fitting surface hold the v shape groove of peripheral band pouring weight, and v shape geosynclinal convex is for output shaft; (5) output shaft is a hollow shaft.Device of the present utility model can be used as speed increaser, if with input shaft change output shaft into, output shaft changes input shaft into, promptly can be used as retarder.According to the difference of usage requirement, change the structure shape of some parts, can obtain being suitable for the dual-purpose speed changer of ball bearing of various requirement.Its major advantage is: (1) is simple in structure, size is little, in light weight.Under the situation of identical rotating speed and transmitted power, it than turbine worm, planetary pinion and gear-shift transmission weight, the low 20-60 of size doubly.(2) efficient height.When reduction speed ratio was 20-60, gear reducer efficient was 0.90-0.93, and the efficient of the utility model device can reach 0.96-0.98.(3) cost is low.It than gear, the low 60-80 of planet gear speed increaser doubly, and is lower 20-80 times than turbine worm, gear and plane table thermoconductivity meter.(4) startup is fast with period of braking.By gear transmission startup and period of braking 2-10 minute with dropped to 30 seconds-2 minutes and 10 seconds-1 minute in 2-5 minute.(5) gear ratio can change continuously.Device of the present utility model is limited by the number of teeth, modulus unlike the gear reducer speed ratio, speed ratio changes continuously with each structural parameter.
