Abstract
The utility model discloses a cantilever-type planetary reduction mining explosion-proof starter, which comprises a large and a small integral-type explosion-proof cavities, wherein the small explosion-proof cavity is divided by a separation plate into a wire connection cavity and an explosion-proof cavity, a rotor, an electric brush and a coil are arranged inside the large explosion-proof cavity, and a clutch mechanism and a planetary reduction mechanism are installed inside a clutch cover on the front end of the large explosion-proof cavity, and is characterized in that: the clutch mechanism comprises a fork shaft and a shifting fork, one end of the shifting fork is connected with the fork shaft, the other end is connected with a clutch shaft with a spline, the planetary reduction mechanism comprises a planetary gear, a planetary shaft and an inner gearing gear, the inner gearing gear is connected with the clutch shaft through the planetary shaft, a ball bearing is installed on the clutch cover to support the clutch shaft, the outer end of the clutch shaft extends out of the clutch cover, and a starting gear is installed on the clutch shaft which extends out of the clutch cover. The starting gear of the mining explosion-proof starter is arranged outside the clutch cover, and the planetary reduction mechanism is adopted, so the weight of the entire machine is reduced, the radial carrying capacity of the starter is strengthened, the output torque of the starter is improved, and the service life of the starter is prolonged.
Description
Technical field
The utility model relates to a kind of starter motor, especially a kind of cantilever type planetary reduction gear flame-proof mine starter motor.
Background technique
The flame-proof mine starter motor is the matching used starting device of explosion-proof locomotive under a kind of and the coal mine, the wheel shaft of existing starter motor starter receiver supports by the oil-impregnated bearing on the clutch cover, starter receiver is contained in the clutch cover, because work under bad environment under the big and coal mine of moment of torsion when starting, cause long, startup frequency height starting time, the support copper sheathing of oil-impregnated bearing is worn and torn easily, using through a period of time like this to make wheel shaft sink, cause starter motor to damage, and then influence the ordinary production and the industry development in colliery.
The model utility content
The purpose of this utility model provides a kind of output torque that improves starting, increases the cantilever type planetary reduction gear flame-proof mine starter motor in working life.
The technical solution of the utility model is: a kind of cantilever type planetary reduction gear flame-proof mine starter motor, comprise two integral type explosion-proof chambers of size, be divided into wire connection cavity and explosion-proof chamber by dividing plate in the little explosion-proof chamber, in big explosion-proof chamber, rotor is housed, brush, stator, carbon brush holder, in the clutch cover of big explosion-proof chamber front end, clutch mechanism and planetary gear speed reducing mechanism are housed, clutch mechanism comprises declutch shift shaft, shift fork, shift fork one end is connected with declutch shift shaft, the other end is connected with the clutch shaft of wounded in the battle key, planetary gear speed reducing mechanism comprises planetary pinion, planet axis and inside engaged gear, inside engaged gear connects with clutch shaft by planet axis, ball bearing is contained in clutch cover upper support clutch shaft, stretch out outside the clutch cover clutch shaft outer end, and starting gear is contained in and stretches out on the outer clutch shaft of clutch cover.
Characteristics of the present utility model:
1, the starter cog with the flame-proof mine starter motor is located at outside the clutch cover, and the weight of whole machine body is alleviated.
2, adopt ball bearing to replace oil-impregnated bearing that the anti-radial force of bearing is improved, make the starting gear of flame-proof mine starter motor combine more reliably with the flywheel ring gear of diesel engine, thereby improve the startability of starter motor, prolong the working life of starter motor.
3, planetary reduction gear can make that the starter motor volume is littler, quality is lighter, output torque is bigger.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model structure is as shown in Figure 1: comprise bonnet 1, connector cover 13, electromagnet 29, needle bearing 42, body 47 and two integral type explosion-proof chambers of size, be divided into wire connection cavity and explosion-proof chamber by dividing plate 22 in the little explosion-proof chamber, in big explosion-proof chamber, rotor 49, brush 8, coil 52 are housed, in the clutch cover 30 of big explosion-proof chamber front end, clutch mechanism and planetary gear speed reducing mechanism are housed, on the clutch shaft of clutch cover outer end, starting gear 39 are installed.This clutch mechanism comprises shift fork 31, and shift fork 31 1 ends are connected with declutch shift shaft, and the other end is connected with the clutch shaft 36 of wounded in the battle key, and planetary gear speed reducing mechanism comprises planetary pinion 44, planet axis 43 and inside engaged gear 45, connects with clutch shaft by planet axis 43 to connect.Angular contact ball bearing 37 is contained in clutch cover upper support clutch shaft, and stretch out outside the clutch cover clutch shaft outer end, and starting gear 39 is contained in and stretches out on the outer clutch shaft of clutch cover.During work, the clutch shaft 36 that shift fork 31 is stirred wounded in the battle key moves, and makes the starting gear 39 that is installed on the clutch shaft start diesel engine with the engagement of anti-explosion diesel engine flywheel ring gear.
The utility model is structure as a whole original clutch mechanism, planetary gear speed reducing mechanism, the external gear of clutch cover this three to combine with existing flame-proof mine starter motor and forms a kind of novel cantilever type planetary reduction gear flame-proof mine starter motor, the starter cog of flame-proof mine starter motor is located at the outer and employing planetary gear speed reducing mechanism of clutch cover, the weight of whole machine body is alleviated, thereby strengthen starter motor bearing capacity radially, improve the output torque of starting, increase the working life of starter motor.
