Description
Technical field
The utility model relates to synchronous machine technical field, particularly a kind of synchronous machine.
Background technology
Because synchronous machine passes through the continuous running of 400 hours under 80 DEG C of ambient temperatures, the grease of the centre bore of main shaft wheel volatilizees or produces; Although grease is arranged at the bottom of main shaft wheel, the grease entering into the centre bore of driving wheel is little, and when main shaft wheel operates when lacking the lubrication of grease, centre bore and central shaft rub and increase, thus produce different sound; If synchronous machine works long hours without when grease lubrication in the centre bore of main shaft wheel, the temperature of main shaft wheel can be made sharply to increase and to cause synchronous machine overheated; For rising problem, the generation of different sound of being badly in need of improving to avoid to work long hours to existing synchronous machine, avoids main shaft wheel and the long-time unlubricated lower friction of central shaft to cause synchronous machine overheated.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of and there will not be the different sound simultaneously motor temperature synchronous machine that can not sharply rise when long-time continuous operates.
For solving the problem, the utility model provides following technical scheme:
A kind of synchronous machine, synchronous machine comprises motor body, main shaft wheel, train of reduction gears, intermediate plate and cover plate, and described motor body is provided with main shaft, the first power transmission shaft, second driving shaft; Described main shaft wheel is provided with the first gear, described train of reduction gears comprises the second gear, the 3rd gear and the 4th gear; The 4th described gear is installed with output shaft; Described main shaft wheel is sheathed on described main shaft; The second described geared sleeve is located on the first described power transmission shaft, and the 3rd described geared sleeve is located on described second driving shaft; Described main shaft wheel is in transmission connection by described train of reduction gears and described output shaft; The bottom of described main shaft wheel is provided with oil storage tank.
Further, the central part of described main shaft wheel offers spindle hole, and the bottom of described oil storage tank offers draws oil groove for being incorporated into by grease in described spindle hole.
Further, the described oil groove that draws is equally distributed three U-type groove of direction of axis line along described main shaft wheel.
Further, the edge of described oil storage tank is provided with chamfering.
Beneficial effect: a kind of synchronous machine of the present utility model, by offering oil storage tank and oiling groove enables grease continue to inject grease in spindle hole bottom described main shaft wheel, avoids the situation that the generation of the different sound of synchronous machine after long time continuous working and temperature sharply rise.

Description of reference numerals: motor body 1, main shaft 11, the first power transmission shaft 12, second driving shaft 13, main shaft wheel 2, the first gear 21, oil storage tank 22, draws oil groove 23, intermediate plate 3, cover plate 4, the second gear the 5, three gear the 6, four gear 7, output shaft 8.
Specific embodiment
Below in conjunction with Figure of description and embodiment, specific embodiment of the utility model is described in further detail:
With reference to a kind of synchronous machine shown in Fig. 1, Fig. 2 and Fig. 4, synchronous machine comprises motor body 1, main shaft wheel 2, train of reduction gears, intermediate plate 3 and cover plate 4, and described motor body 1 is provided with main shaft 11, first power transmission shaft 12, second driving shaft 13; Described main shaft wheel 2 is provided with the first gear 21, described train of reduction gears comprises the second gear 5, the 3rd gear 6 and the 4th gear 7; The 4th described gear 7 is installed with output shaft 8; Described main shaft wheel 2 is sheathed on described main shaft 11; The second described gear 5 is sheathed on the first described power transmission shaft 12, and the 3rd described gear 6 is sheathed on described second driving shaft 13; Described main shaft wheel 2 is in transmission connection by described train of reduction gears and described output shaft 8; The bottom of described main shaft wheel 2 is provided with oil storage tank 22.
Further, the central part of described main shaft wheel 2 offers main shaft 11 hole, and the bottom of described oil storage tank 22 offers draws oil groove 23 for being incorporated into by grease in described main shaft 11 hole.
Further, the described oil groove 23 that draws is equally distributed three U-type groove of direction of axis line along described main shaft wheel 2.
Further, the edge of described oil storage tank 22 is provided with chamfering.
Figure 3 shows that the structure of the main shaft wheel 2 of traditional synchronous machine, the bottom in main shaft 11 hole is right-angle design, need when synchronous machine is assembled in main shaft 11 hole, to inject lubricating grease in advance, when main shaft wheel 2 is installed on main shaft 11, ship the lubricating grease major part be stored in main shaft 11 hole to be discharged, the amount being deposited in the lubricating grease between main shaft 11 hole and main shaft 11 is little, when the long-time continued operation of synchronous machine is that lubricating grease can be told the main shaft wheel 2 of rotation to discharge or by vaporization at high temperature, lubrication is lacked between a main shaft wheel 2 and main shaft 11, final generation abnormal sound, can rise fast along with temperature simultaneously.
It should be noted that the oil storage tank 22 in the utility model can store more lubricating grease, the edge of the oil storage tank 22 simultaneously adopts chamfer design to facilitate lubricating grease to enter in oil storage tank 22, be stored in lubricating grease in oil storage tank 22 to enter in main shaft 11 hole and lubricate by the described oil groove 23 that draws, that avoid different sound with generation that the is zooming phenomenon of temperature.
The above, it is only preferred embodiment of the present utility model, not any restriction is made to technical scope of the present utility model, therefore every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalent variations and modification, all still belong in the scope of the technical solution of the utility model.
