Abstract
The utility model discloses a load balancing device for a planetary reducer, which comprises a planet carrier, a planetary wheel and a sun wheel, wherein sunken rollways which are vertically matched are respectively arranged on the planet carrier and the sun wheel; and rolling elements are arranged in the rollways. The load balancing device has the beneficial effects that: with the constant increase of the load as well as the rollways and the rolling elements, the planetary wheel floats relative to the planet carrier, and thereby the load balancing device has functions of aligning and balancing the load and solves the problem that the stressed loads of the sun wheel and the planetary wheel are non-uniform when the reducer is impacted at high load; and meanwhile, an elastic compensation pad plays a role of buffer, and thus the better load balancing effect is achieved, the fault rate of the reducer is reduced and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of planetary speed reducer load-balancing device, belongs to wind-driven generator functional part technical field.
Background technique
At present, along with wind-driven generator develops to high-power, blower fan and functional part also constantly increase as load, the impact that driftage, change oar speed reducer etc. is subjected to.The means of all carrying of tradition planetary speed reducer more and more can not satisfy the demands, and make the rate of fault of speed reducer strengthen, and shorten working life significantly.
Summary of the invention
For solving above technical deficiency, the utility model provides a kind of planetary speed reducer load-balancing device, be applied in the driftage of high-power blower functional part, the variable paddle speed reducer project engineering, can solve speed reducer when being subjected to big load, impact, the load problem of non-uniform that sun gear, planet wheel are subjected to.
The utility model is realized by following measure:
A kind of planetary speed reducer load-balancing device of the utility model comprises planet carrier, planet wheel and sun gear, and described planet carrier and sun gear are provided with the depression raceway that matches up and down, are provided with rolling element in the described raceway.
For better buffer function is arranged, above-mentioned planet carrier bottom is provided with the elastic compensating pad.
The cross section of above-mentioned raceway is semicircle, and described rolling element is a spheroid, and the aligning effect of load balancing mechanism is better.
The beneficial effects of the utility model are: along with the continuous increase of load, because raceway and rolling element, planet wheel takes place unsteady relatively with respect to planet carrier, all carry function thereby have aligning, solved speed reducer when being subjected to big load, impact, the uneven problem of the load that sun gear, planet wheel are subjected to, the elastic compensating pad also plays buffer function simultaneously, realize better effect of load balancing mechanism, reduce the rate of fault of speed reducer, increase the service life.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1, sun gear, 2, rolling element, 3, the planet wheel retainer, 4, planet wheel, 5, planet carrier, 6, the elastic compensating pad, 7, the secondary sun gear.
Embodiment
As shown in Figure 1, a kind of planetary speed reducer load-balancing device of the present utility model, comprise planet carrier 5, planet wheel 4, planet wheel retainer 3, secondary sun gear 7 and sun gear 1, planet carrier 5 and sun gear 1 are provided with the raceway of the depression that matches up and down, are provided with rolling element 2 in the raceway.For better buffer function is arranged, planet carrier 5 bottoms are provided with elastic compensating pad 6.The cross section of raceway is semicircle, and rolling element 2 is a spheroid, and the aligning effect of load balancing mechanism is better.
Its working principle is:
When receiving big load, rolling element 2 rolls in raceway, and unsteady relatively thereby planet wheel 4 takes place with respect to planet carrier 5, planet wheel 4 is forced to displacement and all carries, and refers to that just aligning all carries, and elastic compensating pad 6 can play certain buffer function.Solved speed reducer when being subjected to big load, impact, the uneven problem of load that sun gear, planet wheel 4 are subjected to, the elastic compensating pad also plays buffer function simultaneously, realizes better effect of load balancing mechanism, reduces the rate of fault of speed reducer, increases the service life.
The foregoing description is described to be in order to specify this patent; though describe by specific term in the literary composition; but can not limit the protection domain of this patent with this; being familiar with the personage of this technical field can be after the spirit of understanding this patent and principle change or revises it and reach equivalent purpose; and this equivalence change and modification all should be covered by the claim scope and define in the category.
