Abstract
The invention relates to a speed-change mechanism. A stepless variable-speed mechanism of the main speed reducer of a good-sized extrusion granulator set comprises a main motor and a secondary motor which are respectively input into a planetary transmission device and output from the output end of the planetary transmission device, wherein the rotating speed of the main motor stays unchanged when the main motor is input into the planetary transmission device, and the secondary motor is a stepless adjusting motor. The structure of the speed-change mechanism is simple and unique in design. The power of one main motor is transmitted to the planetary transmission device to partially form one degree of freedom through an intermediate transmission device, while the power of one secondary motor is transmitted to the same planetary transmission device to partially form another degree of freedom through another intermediate transmission device, so as to constituent a differential mechanism with two degrees of freedom. The novel speed reducer adopting the structure greatly reduces production cost, meets the requirement of technique for rotating speed, and improves the utilization rate of resource.
Description
One. technical field
The present invention relates to gear, particularly the stepless speed changing mechanism of extruder grain unit.
Two. background technique
At present the velocity ratio of the retarder of the large-sized squeezing granulation unit in the petrochemical industry is changeless, promptly single speed or double speed.Because large-size machine will realize that there is very big difficulty technically in stepless change, and cost is high economically, and for the stepless change that requires on the petrochemical iy produced technology, if can realize then even more ideal on retarder.
Three. summary of the invention
The objective of the invention is to overcome existing not enough problem, a kind of stepless speed changing mechanism of large-sized squeezing granulation unit main reducing gear is provided, simple in structure, mechanical stepless speed-changing, cost is lower.
The technological scheme that is adopted for achieving the above object of the present invention is: the stepless speed changing mechanism of large-sized squeezing granulation unit main reducing gear; it inputs to planetary driving device respectively by main motor and auxiliary motor; the output of planetary driving device output terminal; the rotating speed of wherein main motor input planetary driving device is constant, and auxiliary motor is a stepless speed regulation motor.
Described main motor connects main transmission by the lead spindle input, and the main transmission input connects planetary gears, and auxiliary motor connects auxilliary transmission device by auxilliary coupling input, and auxilliary transmission device input connects planetary type gear transmission unit.
Described main motor current is greater than auxiliary motor power.General auxiliary motor power is 0.1 to 0.25 times of main motor current.
Structural design of the present invention is simple, unique, the power of a main motor (power is bigger) passes to planetary driving device by intermediate gearing and partly forms one degree of freedom, and the power of another auxiliary motor (power is less) arrives same planetary driving device by another intermediate gearing and partly forms another degrees of freedom, thereby forms the differential mechanism with two degrees of freedom.The input speed that is come by the bigger main motor transmission of power is constant, and changes the rotating speed of lower-powered auxiliary motor, thereby changes the rotating speed of differential mechanism output, realizes infinite variable speed purpose.Adopt the new type speed reducer of this structure, can be by regulating the input speed of auxiliary motor, the realization retarder is exported the purpose of multiple different rotating speeds, and the velocity ratio that has changed present retarder is the situation of single speed or double speed.When obtaining desirable output speed, greatly reduce manufacture cost, satisfied the requirement of technology to rotating speed, improved the utilization ratio of resource.
