[0002] At present, the wheels on the single-girder bridge crane use LD wheels. This wheel is composed of a driving wheel, a wheel and a toothed plate. The toothed plate is fixed on the wheel with four bolts. Loosening, the tooth plate will be misaligned after loosening, which will cause damage to the tooth plate and the reducer. Since the bearing is a deep groove ball bearing, this kind of bearing has a small load-bearing capacity, short life, and is easy to be damaged. After the wheel is installed on the end beam , the vertical line of the wheel cannot be adjusted, if the vertical line is not good, the crane is easy to gnaw the rail when it is running, so it will affect the quality of the crane

Embodiment Construction
[0008] Embodiments are described in detail in conjunction with the above accompanying drawings, as figure 1 As shown, the wheel shaft 1 is stepped, and one end of the milling slot is used to install the shaft end baffle 8. The center of the end of the milling slot is drilled and tapped, and an oil cup 10 is screwed on it. The purpose is to supply oil to the bearing. The wheel 2 is forged with 45 steel, with a hole in the center. The outer ring of the bearing matches the inner diameter of the driving wheel, and the inner ring matches the wheel shaft 1. The driving wheel uses two spherical roller bearings 6 which are placed with a spacer in the middle. 5. One side is positioned by the step of the shaft, and the other side is positioned by the shaft sleeve 7. The edge gear on one side of the driving wheel meshes with the low-speed shaft of the transmission reducer. There are grooves in the inner hole of the driving wheel, and anti- The dust cover 4 and the circlip 3 are installed...

The invention discloses a wheel of a single girder crane, which comprises a wheel shaft and a driving wheel. The oil cup is connected, the outer ring of the bearing is matched with the inner diameter of the driving wheel, and the inner ring is matched with the wheel shaft. The driving wheel uses two spherical roller bearings with a spacer sleeve placed in the middle, and one side is positioned with a shaft step. The side is positioned with a bushing, the inner hole of the driving wheel has a groove, and the dust cover and the elastic circlip are placed in the groove in turn, the shaft end baffle is stuck in the groove of the wheel shaft and fixed with bolts, the edge of the driving wheel side is slotted with the The low speed shaft of the drive reducer is meshed. The active wheels are made of forged 45 steel. The technical scheme can not only solve the problem of the shedding of the wheel tooth disc, but also improve the bearing capacity of the wheel and prolong the service life.
Description
Technical field: [0001] The invention relates to a crane wheel, which is especially suitable for use on a single beam crane. Background technique: [0002] At present, the wheels on the single-girder bridge crane use LD wheels. This wheel is composed of a driving wheel, a wheel and a toothed plate. The toothed plate is fixed on the wheel with four bolts. Loosening, resulting in misalignment of the toothed plate after loosening, resulting in damage to the toothed plate and the reducer. Since the bearing is a deep groove ball bearing, this kind of bearing has a small load-bearing capacity, short life, and is easy to be damaged, and the wheel is mounted on the end beam. , The vertical line of the wheel cannot be adjusted. If the vertical line is not good, the crane is easy to gnaw the rail when it is running, so it will affect the quality of the crane. Invention content: [0003] The task of the present invention is to propose a single-girder crane wheel that greatly improve...
