Abstract
The utility model discloses a transmission shaft rolling typed radial supporting device, comprising a ring sleeve which is sheathed on the transmission shaft; multi-group of rolling components are circularly arranged between the ring sleeve and the transmission shaft; the rolling components are fixedly connected with the ring sleeve or the transmission shaft; each group of rolling components comprises a bearing seat, a supporting shaft which is arranged on the bearing seat and a rolling bearing which is arranged on the supporting shaft; the rolling components of the transmission shaft rolling typed radial supporting device has simple structure, short processing period and low manufacture cost, therefore the transmission shaft rolling typed radial supporting device has short processing period and low manufacture cost relatively to the large traditional rolling bearings.
Description
Technical field
The utility model relates to a kind of drive axle rolling type radial support apparatus.
Background technique
At present, high-power grid type wind-driven generator is along with continuous advancement in technology, single-machine capacity is increasing, the volume and weight of unit increases thereupon, and the diameter of its transmission shaft is also increasing, will be equipped with the very big traditional bearing of specification on the increasing transmission shaft of diameter, the conventional rolling bearing complex manufacturing technology of this big specification, 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 drive axle rolling type radial support apparatus that can replace conventional rolling 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 drive axle rolling type radial support apparatus of following structure, comprise the ring set that is sleeved on the transmission shaft, its structural feature is many group rolling assemblies that have been periphery between ring set and transmission shaft, rolling assembly ring set and transmission shaft the two one of on affixed, each group rolling assembly comprises bearing support, be contained in the back shaft on the bearing support and be contained in rolling bearing on the back shaft.
Described rolling assembly is fixed in by bearing support on the inwall of ring set, and rolling bearing rolls with transmission shaft and is connected.
Described rolling assembly is fixed on the transmission shaft by bearing support, and the inwall of ring set is provided with annular groove, and rolling bearing rolls with annular groove and is connected, and the outside of annular groove is provided with the baffle ring that is fixed on the ring set end face.
The drive axle rolling type radial support apparatus of said structure, because its rolling assembly is simple in structure, the process-cycle is short, low cost of manufacture, thereby can make this device for the conventional rolling 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:
Fig. 1 is first kind of embodiment's of the utility model a structural representation;
Fig. 2 is the right elevation of Fig. 1;

Embodiment
A kind of drive axle rolling type radial support apparatus as shown in Figure 1 and Figure 2, comprise the ring set 2 that is sleeved on the transmission shaft 1, six groups of rolling assemblies 3 have been periphery between ring set 2 and transmission shaft 1, six groups of rolling assemblies 3 are evenly arranged, each group rolling assembly 3 comprises bearing support 3-1, is contained in the back shaft 3-2 on the bearing support 3-1 and is contained in rolling bearing 3-3 on the back shaft 3-2 that it is two that rolling bearing 3-3 axially is set up in parallel.Each group rolling assembly 3 is fixed in bolt on the inwall of ring set 2 by bearing support 3-1, and rolling bearing 3-3 rolls with transmission shaft 1 and is connected.The interior edge face of the outer ring 3-3-1 of a rolling bearing 3-3 in the position occupies contacts with the shaft shoulder 6 on the transmission shaft 1.
Another kind of drive axle rolling type radial support apparatus as shown in Figure 3, Figure 4, comprise the ring set 2 that is sleeved on the transmission shaft 1, be evenly equipped with six groups of rolling assemblies 3 between ring set 2 and the transmission shaft 1, the structure of the rolling assembly among structure and the embodiment 1 of each group rolling assembly 3 is identical.Each group rolling assembly 3 is fixed on the transmission shaft 1 with bolt by bearing support 3-1, and the inwall of ring set 2 is provided with annular groove 4, and rolling bearing 3-3 rolls with annular groove 4 and is connected, and the outside of annular groove 4 is provided with the baffle ring 5 that is fixed on ring set 2 end faces.The interior edge face of the outer ring 3-3-1 of a rolling bearing 3-3 in the position occupies contacts with baffle ring 5.
The number of rolling assembly 3 is decided according to the diameter and the stressing conditions of transmission shaft 1, and along with the diameter of transmission shaft 1 and stressed increase, the number of rolling assembly 3 also increases thereupon.
The utility model can replace traditional bearing, and ring set 2 is packed on the frame during use.
The drive axle rolling type radial support apparatus of said structure not only can be used on the transmission shaft of large-scale wind driven generator, can also be used for the transmission shaft of other main equipment.
