Abstract
The direct-drive type internal spline wheel comprises an integrated spline wheel, wherein the integrated spline wheel is directly installed with an end beam through a bearing; the integral spline wheel comprises a spline wheel body, wherein a through hole is formed in the spline wheel body and matched with a motor driving shaft. A bearing cover is arranged outside the bearing. The utility model has the advantages that: the integrated spline hollow wheel is directly installed with the end beam through the bearing, is directly driven by the three-in-one gear motor with spline shaft extension, and has the advantages of simple structure, convenience in installation and maintenance, stable operation, low noise and reliable use performance.
Description
Technical Field
The utility model relates to a direct-drive spline wheel which is suitable for a crane.
Background
The novel light crane designed by means of the modern design method is highly favored by the market, gradually replaces an old crane, changes and optimizes the wheel structure by adopting a material with high strength grade in order to ensure the novel light crane to have more reliable performance, more stable operation and lower noise, ensures the overall performance of the crane, and simultaneously ensures that the whole crane has lower weight, smaller seat number of the running gear motor and lower power.
CN 107618973A discloses a bearing box on an euro crane, which comprises a driving wheel shaft, an end beam and a driving wheel, wherein the driving wheel shaft is in a ladder shape, a self-aligning roller bearing is fixed on a step at one end of the driving wheel shaft, a self-aligning roller bearing is fixed on the other end of the driving wheel shaft by a spacer sleeve, the end, connected with a speed reducer, of the driving wheel shaft is made into a flat key or a spline, the self-aligning roller bearing is assembled in a bearing chamber and can not move by being clamped by a convex edge in the self-aligning roller bearing, the convex edge in the bearing chamber is propped against an outer ring of the self-aligning roller bearing, four corners of the bearing chamber are provided with fixing bolt holes connected with the end beam, an inner ring of the self-aligning roller bearing is matched with the driving wheel shaft, the driving wheel shaft is connected with the driving wheel by the flat key, the end beam is arranged at a central opening of the wheel shaft, and the width of the opening is larger than the diameter of the matched position of the driving wheel shaft and the self-aligning roller bearing, and can be directly matched with high-quality speed reducers such as SEW and ABM. This solution, although also involving wheels on cranes, is not direct-drive, but still has components such as wheel axles, and the structure is relatively complex.
Disclosure of Invention
The purpose of the utility model is that: the crane has the advantages that the integral use performance of the crane is met, meanwhile, the product structure is more exquisite and attractive, the weight of the whole crane is low, the cost is saved, the performance is improved, and the product is optimized.
The object of the utility model is achieved in the following way:
the direct-drive type internal spline wheel comprises an integrated spline wheel, wherein the integrated spline wheel is directly installed with an end beam through a bearing; the integral spline wheel comprises a spline wheel body, wherein a through hole is formed in the spline wheel body and matched with a motor driving shaft.
A bearing cover is arranged outside the bearing.
Compared with the prior art, the utility model has the advantages that: the integrated spline hollow wheel is directly installed with the end beam through the bearing, is directly driven by the three-in-one gear motor with spline shaft extension, and has the advantages of simple structure, convenience in installation and maintenance, stable operation, low noise and reliable use performance.
