Abstract
The utility model discloses a transmission shaft rolling typed axial supporting device, comprising a transmission shaft; the supporting device comprises multi-group of rolling components which have the same structure, are circularly arranged and fixedly connected on the end surface of the transmission shaft; the multi-group of rolling components can roll in the same plane; the rolling components comprise a bearing seat which is fixedly connected with the transmission shaft, a supporting shaft which is arranged on the bearing seat and a rolling bearing which is arranged on the supporting shaft; the end surface of the supporting shaft and the end surface of the transmission shaft are obliquely arranged on the bearing seat; the rolling bearing is sheathed with a conical sleeve; the conicity of the conical sleeve is the same as the inclination angle of the supporting shaft. When in use, the multi-group of rolling components are circularly arranged and fixedly connected on the end surface of the transmission shaft; the conical sleeves of the multi-group of rolling components are attached to an axial force bearing device of a wind motor. As the supporting device consists of multi-group of rolling components which have simple structure, short processing period and low manufacture cost, the supporting device has short processing period and low manufacture cost relatively to the large traditional thrust bearing.
Description
Technical field
The utility model relates to a kind of roller axial supporting device for driving shaft.
Background technique
At present, high-power grid type wind-driven generator is along with continuous advancement in technology, and single-machine capacity is increasing, and the volume and weight of unit increases thereupon, and the diameter of its transmission shaft is also increasing.In order to bear the axial force of transmission shaft, need on transmission shaft, adorn the very big traditional thrust-bearing of specification, this big specification thrust-bearing complex manufacturing technology, the manufacturing cycle is long, and the cost height is seriously restricting the manufacturing speed and the cost of production of large-scale wind driven generator.
The model utility content
The technical problems to be solved in the utility model is at above-mentioned defective, and a kind of roller axial supporting device for driving shaft that can replace traditional thrust-bearing that the large-scale wind driven generator transmission shaft is used that is suitable for is provided, and this device can shorten the manufacturing cycle, reduces production costs.
For solving the problems of the technologies described above, the utility model provides a kind of roller axial supporting device for driving shaft of following structure, comprise transmission shaft, its structural feature is: this support device comprises the rolling assembly on the many groups of identical transmission shaft end faces that are periphery and are fixed in of structure, and described many group rolling assemblies can be along same plane rolling.
Described rolling assembly comprises the bearing support affixed with transmission shaft, be contained in the back shaft on the bearing support and be contained in rolling bearing on the back shaft, back shaft and transmission shaft end face are skewed and are contained on the bearing support, be set with conical sleeve on the rolling bearing, the tapering of conical sleeve is identical with the angle of inclination of back shaft.
The roller axial supporting device for driving shaft of said structure during use is periphery many group rolling assemblies and is fixed on the end face of transmission shaft, the axial force holder of the conical sleeve of many group rolling assemblies and wind-driven generator is adjacent to gets final product.Because this support device is made of many groups rolling assembly, rolling assembly is simple in structure, and the process-cycle is short, low cost of manufacture, thereby can make this support device for traditional thrust-bearing of big specification, its process-cycle is short, low cost of manufacture.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
