[summary of the invention]
The present invention has overcome the deficiency of prior art, provides simple in structure, a kind of compact MW class wind turbine group gear box test table rear end seal cover easy to use.
Be provided with the axis hole that supplies gearbox output shaft to pass in the middle of a kind of wind-driven generator group wheel box testing table rear end seal cover, rear end seal cover, back-end sealing covers and is provided with three syndetons, is divided into first syndeton, second syndeton and the 3rd syndeton;
The a pair of coaxial cylindrical support arm that first syndeton is provided with for the rear end seal cover excircle; Rear end seal cover is suspended on the gear box test table base to support whole gear case through first syndeton; Adopt the cylindrical support arm good, be easy to assembling and regulate and dismantle neutrality;
Second syndeton is a plurality of connecting holes of offering on the lid acies face of rear end seal cover, and second syndeton realizes being tightly connected through bolt and gear case;
The 3rd syndeton is the circle connecting hole that axis hole outer end circumference is offered, and the 3rd syndeton is tightly connected through the rotary components of bolt and support teeth roller box output shaft.Because the singularity of wind-driven generator group wheel box structure; Need the gearbox output shaft of high speed rotating be provided support; So designed gear box test table rotary components together support gearbox output shaft; The rotary components outer end is with the capping of swelling adapter sleeve, and rotary components then is to be connected with rear end seal cover through bolt to fix; That is to say, rear end seal cover, rotary components and swelling adapter sleeve formed one the rotation support system, together support gearbox output shaft.
Further improve, back-end sealing covers to be provided with and is communicated with inside and outside oil return line hole, and the oil return line hole has a plurality of, and a plurality of oil return lines hole is divided into rear end seal cover lid edge bottom side and axis hole bottom side.The lid edge bottom side of rear end seal cover and axis hole bottom side are designed with oil return line hole and thorough consideration aperture size, can prevent problems such as oily temperature that gear case causes because of oil return is untimely is high excessively, have reduced the inaccurate possibility of gear case test data.
Further improve, rear end seal cover is the lid of whole machine work moulding, has reduced the rigging error between part.
Further improve; Be respectively equipped with the O RunddichtringO between rear end seal cover and gear case and rear end seal cover and the rotary components; Whole like this rear end seal cover sealing gear case; And then adopt the sealing of O RunddichtringO with gear case, rotary components end face connecting portion, thereby be isolated from the outside lubricating oil.
The present invention with respect to the beneficial effect of prior art is: the present invention proposes a kind of compact MW class wind turbine group gear box test table rear end seal cover structural design new departure; Its design has following 4 advantages: 1, rear end seal cover support function and sealing function are integrated; Reduced parts design; Reduce production cost, improved test reliability; 2, rear end seal cover sealing gear case; And then adopt the sealing of O RunddichtringO with gear case, rotary components end face connecting portion; Thereby be isolated from the outside lubricating oil, adopt the lubricated and Cooling Design of oil circuit of enclosure-type simultaneously, be designed with oil return line hole and thorough consideration aperture size in the lid edge bottom side and the axis hole bottom side of rear end seal cover; Can prevent problems such as oily temperature that gear case causes because of oil return is untimely is high excessively; Reduce the inaccurate possibility of gear case test data, taken into full account the anti-pollution of oil circuit, helped oily temperature control; 3, rear end seal cover cylindrical support arm design, good to neutrality, can guarantee the right alignment of two installation shaft to greatest extent, and be easy to dismounting; 4, rear end seal cover adopts whole machine work, has reduced the rigging error between part.
