Abstract
A large-sized speed increasing box shock absorption mechanism belongs to improvement for partial structures of wind generators, and comprises a speed increasing box and a cabin base. The large-sized speed increasing box shock absorption mechanism is characterized by further comprising a shock absorption base fixed onto the cabin base by the aid of a bolt group; a circular through hole is arranged inside the shock absorption base; an elastic sleeve is sleeved inside the through hole; a steel shaft integrated with the speed increasing box is sleeved inside the elastic sleeve; and the elastic sleeve sequentially consists of a rubber layer, a steel plate layer, a rubber layer and a steel plate layer in a composite manner. The large-sized speed increasing box shock absorption mechanism can be used for effectively reducing the negative influence of shock of a wind generating unit on a transmission mechanism and further ensuring long-term maintenance-free running of the wind generating unit.
Description
Technical field
The utility model is the improvement at the partial structurtes of wind-driven generator, specifically a kind of large-scale speedup box damper mechanism.
Background technique
In large-scale wind generating equipment, speedup box is important function parts, and its main function is that the transmission of power that wind wheel is produced under the wind-force effect is given generator and made it obtain corresponding rotating speeds.Usually the rotating speed of wind wheel is very low, does not far reach the desired rotating speed of generator for electricity generation, must be used for by the speedup of speedup box realizing.
Wind-power electricity generation is subjected to the influence of natural condition bigger, and the appearance of some special meteorological conditions all may cause the wind-powered electricity generation unit to break down, and narrow and small cabin can not be as have firm support basis ground.The power coupling of whole drive system and the factor of torsional vibration are always embodied a concentrated reflection of on certain weak link, and a large amount of facts have proved, this link usually is the speedup box in the unit.Therefore, be one of design object reduce the harm of environmental factor as far as possible to speedup box.
The ability of speedup box opposing vibrations will directly influence the working life of wind power generating set, require to guarantee enough rigidity during design, and certain elasticity is arranged again, make it to realize long-term non-maintaining operation.
The model utility content
The purpose of this utility model is to provide a kind of large-scale speedup box damper mechanism, is used to alleviate the adverse effect of the vibrations of wind power plant to driving mechanism, and then guarantees the long-term non-maintaining operation of wind-powered electricity generation unit.
The technical scheme in the invention for solving the technical problem is: the large-scale speedup box damper mechanism of this kind, comprise speedup box and engine room foundation, it is characterized in that, also comprise by the bolt group and be fixed on damping base on the engine room foundation, be provided with manhole in the described damping base, be nested with resilient sleeve in the described through hole, be nested with steel axle in the described resilient sleeve with the speed reducer one.
Described resilient sleeve is composited by rubber layer, steel plate layer, rubber layer, steel plate layer from inside to outside successively.
Effectively be nested with thickness on the bolt of described bolt group and be at least the shock absorbing sleeve of three centimetres rubber material.
The beneficial effects of the utility model are: install and use by of the present utility model, can effectively alleviate the adverse effect of wind power generating set vibrations to driving mechanism, and then guarantee the long-term non-maintaining operation of wind-powered electricity generation unit.
Description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the A-A end view drawing of Fig. 1;
Among the figure: 1 speedup box, 2 engine room foundations, 3 damping base, 4 resilient sleeves, 5 steel axles, 6 bolts, 7 shock absorbing sleeves.
Embodiment
As shown in Figure 1 and Figure 2, the large-scale speedup box damper mechanism of this kind comprises speedup box 1, engine room foundation 2, also comprises by the bolt group being fixed on damping base 3 on the engine room foundation.This damping base is arranged between speed reducer and the engine room foundation, is used to reduce the vibrations of speedup box.
For further strengthening damping effect, effectively be nested with the shock absorbing sleeve 7 that thickness is at least three centimetres rubber material on the bolt 6 of bolt group.
Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
