Abstract
The utility model relates to a tube shaft support in a wind driven generator gear case. The tube shaft support comprises hollow tube shafts. Supporting points, located on the input sides, of the tube shafts are input planet carriers in the gear case, and supporting points, located on the output sides, of the tube shafts are transparent covers of a back case body. The tube shaft support is characterized in that the tube shafts located on the input sides are supported on the input planet carriers through bearing bushes, the tube shafts located on the output sides are fixed on the transparent covers through reamed hole bolts, and then the tube shafts are fixedly connected with the back case body through the transparent covers.
Description
Technical field
The tubular axis that the utility model relates in a kind of wind-driven generator wheel-box supports.
Background technique
Wind-power electricity generation is compared with traditional thermal power generation, has the free of contamination advantage of generating, compares with hydroelectric power, have that the capital construction cost is low, floor space is little, maintaining is advantage easily, and especially large-scale hydroelectric power plant, storage reservoir also easily cause certain potential safety hazard to the downstream.In wind-driven generator, gear-box is the critical component of wind-driven generator, and the accelerating gearbox for wind power generator of China's use at present is generally overall structure, and the dismounting difficulty in case break down, can only be changed assembly, causes waste.
Although gear-box is improved, casing is carried out necessary classification, preferably resolve the dismounting difficulty, avoided the replacing assembly, reduced maintenance cost, but, we find, due to tubular axis two ends respectively on the transparent cover by the input planet carrier in the bearings gear-box and rear box, in gear-box work, tubular axis very easily rotates with input star frame, and cable easily weares and teares; Simultaneously, slowly run owing to belonging to underloading between tubular axis and planet carrier, rolling bearing can shorten bearing life easily producing relative sliding in underloading low speed situation between rolling element and raceway.
The model utility content
The purpose of this utility model is: for cable in traditional wind power generation gear case pass gear-box problem easy to wear and rolling bearing in the low speed underloading drawback and the tubular axis that designs supports.
The purpose of this utility model is achieved in that the tubular axis in a kind of wind-driven generator wheel-box supports, comprise hollow tubular axis, the strong point that tubular axis is arranged in input side is the input planet carrier of gear-box, the strong point that is positioned at outlet side is the transparent cover of rear box, it is characterized in that: the tubular axis that is positioned at input side is supported in the input planet carrier by bearing shell, the tubular axis that is positioned at outlet side is fixed on transparent cover by hinged bolts, then is fixedly connected with rear box by transparent cover.
The utility model has the advantage of: due to tubular axis and planet carrier point of contact employing bearing shell, solved the drawback that rolling bearing easily skids; Because oil film between bearing shell and tubular axis is more stable, relatively friction is less, has extended tubular axis working life; Because the transparent cover of tubular axis by rear box is fixedly connected with gear-box, do not rotate with planet carrier, stopped to relatively rotate the wearing and tearing to cable that cause, effectively protected cable.
Description of drawings
Fig. 1 is the position view of the utility model embodiment in gear-box.
Fig. 2 is that the utility model embodiment is at the structural representation of the gear-box input side strong point.
Fig. 3 is that the utility model embodiment is at the structural representation of the gear-box outlet side strong point.
In figure, 1, bearing shell, 2, the input planet carrier, 3, transparent cover, 4, hinged bolts, 5, tubular axis.
Embodiment
Accompanying drawing discloses the utility model embodiment's concrete structure without limitation, below in conjunction with accompanying drawing, the utility model is done to describe further.
As shown in Fig. 1 ~ 3, the utility model comprises hollow tubular axis 5, the strong point that tubular axis 5 is arranged in input side is the input planet carrier 2 of gear-box, the strong point that is positioned at outlet side is the transparent cover 3 of rear box, wherein: the tubular axis 5 that is positioned at input side is supported in input planet carrier 2 by bearing shell 1, the tubular axis 5 that is positioned at outlet side is fixed on transparent cover 3 by hinged bolts 4, then is fixedly connected with rear box by transparent cover 3.
Because tubular axis 5 is hollow shafts, pass gear-box for the protection of cable.During work, input planet carrier 2 rotates, and tubular axis 5 can not rotate with planet carrier.
