Detailed Description

The utility model is further elucidated below in connection with the accompanying drawings.

As shown in fig. 1, 2 and 3, the utility model relates to a gear motor, which is used for driving a main shaft of a parking spot lock to rotate when being used for the parking spot lock, so as to drive a rocker arm of the parking spot lock to finish a lifting function. Because the rocker arm is driven by a large moment when ascending and the rocker arm descends at a high speed, a speed reducing motor is generally used for driving the rocker arm to ascend and descend.

The motor 10 is provided with an output shaft. Here, a first fixing plate 21 and a second fixing plate 22 are provided under the motor 10, and are fixedly connected by 4 screws (24, 25, 26, 27) for placing a gear set (11, 30, 40, 50, 60) for transmission. The first gear 11 is tightly matched with the output shaft of the motor 10, and the second, third and fourth gears are duplex gears and are composed of two gears with a large diameter and a small diameter.

As shown in fig. 2, 4 and 5, fig. 2 is a schematic diagram of the gear set transmission principle of the present utility model, in which the gear set is unfolded to show the meshing relationship between gears, and fig. 4 and 5 are upper and lower views of the schematic diagram of the gear set structure of the present utility model.

The transmission principle of the working gear set of the utility model is as follows: the first gear 11 is fixedly sleeved on the output shaft of the motor 10. The second, third and fourth gears are respectively provided with a gear shaft (31.41.51), two ends of the gear shafts (31, 41, 51) are respectively arranged on the first fixing plate 21 and the second fixing plate 22 and are in tight fit, and loose fit is formed between the gears and the gear sets. When the gears operate, the gear shafts are blocked between the first fixing plate 21 and the second fixing plate 22 and cannot move.

The first gear 11 is a single gear, which is meshed with the large gear of the second gear 30, the small gear 32 of the second gear 30 is meshed with the large gear of the third gear 40, the small gear 42 of the third gear 40 is meshed with the large gear of the fourth gear 50, the small gear 52 of the fourth gear 50 is meshed with the driving gear 60, the driving gear 60 is a single gear, and all gears are arranged in straight teeth, i.e. the gear shafts are arranged in a straight line along one direction.

The second, third and fourth gears are duplex gears, namely two gears with large and small diameters are combined, so that the gears of the gears are partially overlapped in the vertical direction, and the arrangement is more compact. Through the design of duplex gear, can be better with the better matching of parking stall lock. Of course, the first gear may be replaced by a similar device, such as a worm, which also achieves the function and effect of the present utility model, while remaining within the scope of the utility model.

As shown in fig. 1 and 2, a washer 12 is disposed between the first fixing plate 21 and the motor 10 for better fixing the motor 10, and meanwhile, the thickness of the washer 12 can be adjusted according to the length of the output shaft of the motor, that is, the distance between the first fixing plate 21 and the second fixing plate 22 is adjusted, so that the structure of the gear motor is more compact.

The outer side of the second fixing plate 22 is provided with a cover plate 23. A drive shaft 61 (fig. 5) is provided in the middle of the output gear 60, and passes through the second fixing plate 22 and the cover plate 23. Because the first fixed plate and the second fixed plate are provided with a plurality of counter bores for installing the gear shaft, the cover plate has attractive effect besides the fixed second fixed plate.

The utility model adopts 2 fixing plates, is convenient to install and debug and is convenient to maintain.
