Abstract
The utility model relates to a stepless speed regulating small-sized winch for mine, which solves the problems of low efficiency of a small-sized winch for mine and large noise. Besides, the small-sized winch for mine can not stepless regulate speed. The utility model adopts a driving motor to connect with the large positive wheel shaft of a planetary differential speed reducer; the driving speed reduction gear group of a planetary frame is connected with a barrel shaft; an inner gear is connected with a speed regulation wheel by a gear group; a brake is arranged in the speed regulation wheel. The utility model has the advantages of low running noise, high efficiency, long service life, low cost and convenient maintenance. The utility model is more ideal winch for mine.
Description
The utility model relates to a kind of mining infinite speed variation puffer device.
At present, domestic existing mining infinite speed variation puffer, the overwhelming majority still is the imitated Soviet Union of the fifties, its technical performance falls behind, JT800X600-30 winch as the imitative Soviet Union, adopt the one-level drop-gear box to add a pair of exposed gear transmission, driving efficiency is low, and noise is big, and makes difficulty, because the big gear wheel on the reel is a steel casting, the casting difficulty is big, and it is to adopt the common electric machine can not speed governing that big gear-hobbing machine, the shortcoming of the old-fashioned winch maximum of this kind are wanted in processing, even adopt winding motor to change rheostatic speed regulation, but speed adjusting performance is bad in the low-speed range.Moreover this kind mode of speed control, owing to do not have the Wound-rotor type fire proof motor, so can not go down into a mine.
The purpose of this utility model is to provide a kind of noise little, the efficient height, and the life-span is long, is easy to make, and cost is low, reliability height, mining infinite speed variation puffer easy to maintenance.
The utility model is finished with following mode: mining infinite speed variation puffer includes driving motor 1 and reel 3, big positive wheel shaft 2-4 with planet differential retarder 2 is connected with motor 1, transmission train of reduction gears with planet difference speed reducer 2 links to each other with the transmission shaft 3-1 of reel 3, planetary differential 2 has drg 4-2 through the fly wheel governor 4-1 of gear cluster connection speed regulation device 4 on fly wheel governor 4-1.Pinion carrier 2-3 or inner gear 2-5 transmission train of reduction gears with planet differential retarder 2 link to each other with the transmission shaft 3-1 of reel 3.Reel 3 coaxial brake wheel and the drg 3-2 of being equipped with.
The utility model is mining, and the infinite speed variation puffer all is contained in transmission gear spare in the casing, and good seal performance is lubricated, it is little to wear and tear, and the life-span is long, the driving efficiency height, planet differential mechanism adopts inner gear to float, and it is very steady to turn round, and noise is little, and keep in repair very convenient, be easy to make, cost is low, and its speed governing is simple to operate, good speed adjustment features is a kind of desirable mining puffer.
Fig. 1 is the utility model transmission principle figure.
Fig. 2 is the concrete structure figure of a kind of embodiment of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, the utility model is mining, and the infinite speed variation puffer is to connect planet differential retarder 2 by driving motor 1, and the drum load 3 of band brake device connects planet differential retarder 2, and speed regulation device 4 connects planet differential retarder 2.The utility model embodiment is connected by flexible pillar pin coupling (or flexible pillar pin coupling of band brake wheel) 1-1 the sun wheel shaft 2-4 of planet differential retarder 2 as shown in Figure 2 with driving motor 1.The pinion carrier 2-3 of planet differential retarder 2 or inner gear 2-5 are connected with spool spindle 3-1 by gear 2-9, gear 2-7, gear 2-6, the gear 2-8 of train of reduction gears, and unsteady inner gear 2-5 of planet differential retarder 2 (also can make do not float) or the meshing gear 2-2 of pinion carrier 2-3 are connected with fly wheel governor 4-1 with gear 2-1, brake wheel and drg 3-2 are arranged on the spool spindle 3-1, drg 4-2 is arranged on the fly wheel governor 4-1.The utility model puffer also has the chassis, the control button of electric control circuit, magnetic starter etc.Operate two handles by the operator, just can realize that control promotes, and transfers the various running statees of load.As rotating speed, by the rotation of right handles control reel 3 by left handle control fly wheel governor 4-1.When left handle not during the application of force, be that drg 4-2 opens, fly wheel governor 4-1 is in free state, driving motor 1 can starting under no load (disregarding mechanical wear), the power that applies when left handle is from small to large the time, drg 4-2 progressively holds fly wheel governor 4-1 tightly, this moment fly wheel governor 4-1 rotating speed from high to low, the kinematic velocity of spool spindle (load) 3-1 is also just from small to large.When fly wheel governor 4-1 is checked, reel (load) 3-1 kinematic velocity reaches maxim (being command speed), the power that applies when left handle is from big to small the time, be that drg 4-2 progressively leaves fly wheel governor 4-1, the rotating speed of fly wheel governor 4-1 from low to high at this moment, the kinematic velocity of reel (load) 3-1 also just from big to small, Here it is, and the utility model carries out the principle of speed governing according to power dividing, and drg 3-2 just in case of emergency, the right handles application of force, 3-1 checks with spool spindle (load), and left handle is put the not application of force simultaneously, and motor is in unloaded the rotation.
