Planetary bevel gear driving device of crane running mechanism

Technical Field

The utility model belongs to the technical field of hoisting equipment, especially, relate to a planet bevel gear drive arrangement of hoist running gear.

Background

The working principle of the conventional driving device of the crane operating mechanism is as follows: the motor is used for driving the speed reducer, and an output gear shaft of the speed reducer is meshed with an outer gear ring of the wheel so as to drive the wheel to rotate. However, the speed reducer of the driving device in the prior art is usually disposed on one side of the outer portion of the end beam of the crane or the end beam of the trolley, and is disposed parallel to the wheels of the cart or the trolley, and the external gear ring is fixed on one side of the wheels and is disposed parallel to the wheels, and this arrangement mainly has the following disadvantages: the reducer and the motor occupy a large space of the crane, collision interference is easy to generate, and the use space of the whole running mechanism is limited in some special occasions and the use requirement cannot be met; and (II) a pair of outer gear rings fixed with the wheels needs to be arranged, and the outer gear rings need larger modules, so that not only is material wasted, but also the service life of the outer gear rings can be greatly shortened, and the maintenance is inconvenient.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a hoist running gear's planet bevel gear drive arrangement for it is unreasonable to solve among the prior art hoist running gear drive arrangement's structural design, thereby leads to drive arrangement to occupy the very big space of hoist, can not satisfy the user demand, and needs to set up a pair of outer ring gear fixed with the wheel, inconvenient technical problem of maintaining.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides a hoist operating device's planet bevel gear drive arrangement, including the end beam, the both ends of end beam lower part are all rotated and are connected with the wheel, and the top of end beam is equipped with drive arrangement, drive arrangement is including setting up the driving motor in the end beam top, and driving motor's the vertical downward setting of output shaft, driving motor's output shaft transmission is connected with the reduction gear, and the reduction gear is located driving motor under, and the reduction gear is fixed at the end beam top, and the mounting hole has been seted up at the top of end beam, and the output shaft of reduction gear runs through the mounting hole and extends to inside the end beam, and fixed cover is equipped with the umbellate form gear on the output shaft of reduction gear, and the fixed cover in periphery of wheel.

The speed reducer is a planetary speed reducer.

The central axis of the output shaft of the driving motor and the central axis of the output shaft of the speed reducer are positioned on the same straight line and are vertical to the central axis of the wheel.

The end beam is a crane end beam or a trolley end beam.

The utility model has the advantages that: the structure is simple and compact, the reducer is arranged right below the driving motor, the central axis of the output shaft of the reducer is vertical to the central axis of the wheel, and the installation space of the driving device is reduced, so that the use requirements of some special occasions are met, and the application range is expanded; and the wheel is directly driven through the bevel gear and the bevel gear ring, an external gear ring is not required to be additionally arranged outside the wheel, and the use and the maintenance are convenient.
