Abstract
The utility model relates to a wind-driven generator yaw speed reducer for preventing oil leakage, which comprises a casing (1), and a four-stage planetary mechanism (6) arranged inside the casing (1). An input shaft and an output shaft are respectively arranged at the top and the bottom of the four-stage planetary mechanism (6) protruding out of the casing (1), an oil pointer (2) is arranged on the outer wall of the upper part of the casing (1), and the lower end thereof communicates with the casing (1), and an oil filling hole (3) and a dustproof air permeable hat (4) are arranged on the top of the casing (1). The yaw speed reducer is characterized in that an opening at the upper end of the oil pointer (2) is connected with the oil filling hole (3) via an oil return pipe (5). Compared with the prior art, the yaw speed reducer removes a stopper for plugging the oil pointer and the oil filling hole on the original basis, the oil pointer communicates with the oil filling hole via the oil return pipe, so as to effectively solve the problem of lubricating oil leakage from the opening at the upper end of the oil pointer for a long time, without increasing additional expense in cost and assembly; meanwhile, the threaded connection between the oil return pipe and the oil pointer and between the oil return pipe and the oil filling hole is very firm.
Description
Technical field
The utility model belongs to the wind driven generator yaw retarder, specifically, is the wind driven generator yaw retarder of the anti-leakage of oil of a kind of energy.
Background technique
Wind-power electricity generation is compared with traditional thermal power generation, advantage with environmentally safe, in the wind-driven generator, yawing speed reducer is the very important parts of wind-driven generator, because the direction of wind is constantly to change, and the size of wind-force, the height of wind speed also is constantly to change, the effect of yawing speed reducer selects to aim at or depart from wind direction exactly, guarantee that the gear-box output speed is specified constant, present wind driven generator yaw retarder, comprise casing 1 as shown in Figure 3, in this casing 1 level Four planetary mechanism 6 is housed, external wall of upper portion is provided with oil ga(u)ge 2, these oil ga(u)ge 2 lower ends communicate with casing 1, described casing 1 top is provided with tank filler sleeve 3 and dustproof ventilative cap 4, during the work of wind driven generator yaw retarder, oil ga(u)ge aperture, 2 upper end and tank filler sleeve 3 all are to stop up with plug, head stops up though this aperture, structure oil ga(u)ge 2 upper end is blocked, also be provided with dustproof ventilative cap 4, but during casing 1 work because the air on temperature rising lubricant oil and its top can expand, internal pressure is very big, ventilative a period of time of the dustproof simultaneously cap 4 of breathing freely is very limited, and lubricant oil can be through the gap between oil ga(u)ge aperture, 2 upper end and the plug plug to external leakage in the casing 1.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of wind driven generator yaw retarder that can prevent to leak lubricant oil.
The technical solution of the utility model is as follows: the wind driven generator yaw retarder of the anti-leakage of oil of a kind of energy, comprise casing and be contained in the interior level Four planetary mechanism of casing, this level Four planetary mechanism stretches out the casing top and input shaft and output shaft are arranged respectively at the bottom, this casing external wall of upper portion is provided with the transparent oil ga(u)ge that can observe oil level of sidewall, this oil ga(u)ge lower end communicates with casing, described casing top is provided with tank filler sleeve and dustproof ventilative cap, its key is: described oil ga(u)ge upper end links to each other with tank filler sleeve by return tube, when yawing speed reducer is worked, level Four planetary mechanism in the casing transmits outputting power, because the air on temperature rising lubricant oil and its top can expand in the casing, internal pressure is very big, the ventilative effect of dustproof ventilative cap is very limited simultaneously, lubricant oil can upwards ooze through oil ga(u)ge upper end oral area under pressure in the casing, flows back in the casing once more from tank filler sleeve by return tube.Described return tube two ends is provided with coupling nut, is threaded with oil ga(u)ge and tank filler sleeve, and what energy was firm is connected with the oil ga(u)ge upper end return tube with tank filler sleeve.
The utility model compared with prior art gets on original basis except the plug of stifled oil ga(u)ge and tank filler sleeve, and with a return tube both are communicated with, in cost and assembling, do not increase expense, but efficiently solve the problem that oil ga(u)ge upper end oral area for a long time outwards leaks machine oil, return tube and oil ga(u)ge and tank filler sleeve adopt very firm of being threaded simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the structural representation before improving.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, the utility model can be prevented the wind driven generator yaw retarder of leakage of oil, casing 1 by interior dress level Four planetary mechanism 6, oil ga(u)ge 2, return tube 5, tank filler sleeve 3 and dustproof ventilative cap 4 are formed, these oil ga(u)ge 2 lower ends communicate with casing 1, described casing 1 top is provided with tank filler sleeve 3 and dustproof ventilative cap 4, and wherein said oil ga(u)ge 2 upper ends link to each other with tank filler sleeve 3 by return tube 5.Described return tube 5 two ends are provided with coupling nut 5a, are threaded with oil ga(u)ge 2 and tank filler sleeve 3.During yawing speed reducer work, level Four planetary mechanism 6 in the casing 1 transmits outputting power, because the air on temperature rising lubricant oil and its top can expand in the casing 1, internal pressure is very big, the ventilative effect of dustproof ventilative cap 4 is very limited simultaneously, lubricant oil can upwards ooze through oil ga(u)ge 2 upper end oral areas in the casing 1, flows back to once more in the casing 1 from tank filler sleeve 3 by return tube 5, has avoided the leakage of lubricant oil in the casing 1.
