Description
Technical field
The utility model relates to a kind of testing apparatus, is specifically related to a kind of toque force of wind power bearing equipment.
Background technology
China is marching this piece of wind-power electricity generation brand-new " pollution-free industry ", and in the home market, accurate large size bearing is mainly based on import at present, and industry downstream client's development in recent years of large-scale precision bearing is rapid, and supply falls short of demand to cause above-mentioned precision bearing.Render a service in order to make aerogenerator promote generating, increase generated output, the size at positions such as the length of blade, main shaft, speed-increasing gear, generator is also in continuous expansion, but also increase gradually of the loading that the while bearing is born, this technical requirement to wind power bearing is very high.Aerogenerator is strict unusually to the technical requirement of its core component bearing, and each wind power bearing all must be tested its torsion after installing, and comprises static and dynamic.Therefore developing a kind of toque force of wind power bearing platform is the task of top priority that sets foot in wind power equipment manufacturing enterprise.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of toque force of wind power bearing equipment that manufactures and designs for the large-scale wind electricity bearing is provided, and it can measure the torsion of installation rear bearing accurately, reliably.
A kind of technical scheme that realizes above-mentioned purpose is: a kind of toque force of wind power bearing equipment, described wind power bearing is the pivoting support bearing that the outer peripheral face that all has mounting hole and inner ring inner peripheral surface or outer ring on the end face of inside and outside circle is provided with gear, and described torsional test equipment comprises:
The base of one solid bearing, it has three feets at least, is equipped with a dovetail groove on the top end face of these three feets, and described wind power bearing is inlaid in this dovetail groove and by bolt bearing inner race or outer ring is fixed;
One platform, it fixedly is located at vertical fixing a positioning rod on one side of base and its top end face;
The upper end of the backstay on one cylinder, the rear end that it flatly is arranged on the side top of platform and its cylinder body and platform is connected;
One pulling force digital indicator, it is connected on the inner ring or outer ring of wind power bearing with the coaxial setting of cylinder and its front end, and its rear end is connected with the piston rod front end of cylinder.
Above-mentioned toque force of wind power bearing equipment wherein, is fixed a pin in the mounting hole of described wind power bearing inner ring or outer ring, and described pulling force digital indicator is connected with wind power bearing by the draw ring that can be sleeved on the pin that its front end connects.
Above-mentioned toque force of wind power bearing equipment, wherein, described pulling force digital indicator is one to have the extension spring of digital display screen.
Adopt the technical scheme of toque force of wind power bearing equipment of the present utility model, can measure the torsion of wind power bearing after the installation accurately, reliably.This device structure advantages of simple, easy to operate, flexible.
Description of drawings
Fig. 1 is the structure front elevation of toque force of wind power bearing equipment of the present utility model;
Fig. 2 is the structure vertical view of toque force of wind power bearing equipment of the present utility model.
Embodiment
In order to understand the technical solution of the utility model better, below by embodiment particularly and be described in detail in conjunction with the accompanying drawings:
See also Fig. 1 and Fig. 2, toque force of wind power bearing equipment of the present utility model, tested wind power bearing 1 is the single-revolution block bearing, the outer peripheral face that is equipped with mounting hole and inner ring or outer ring on the end face of its inside and outside circle is provided with gear.
Torsional test equipment comprises: a base 2, a platform 3, a cylinder 4 and a pulling force digital indicator 5, wherein,
Pulling force digital indicator 5 is one to have the extension spring of digital display screen, and it is connected on the inner ring or outer ring of wind power bearing 1 with cylinder 4 coaxial settings and its front end, and its rear end is connected with piston rod 42 front ends of cylinder 4.
Toque force of wind power bearing equipment of the present utility model is when the torsion of test bearing, earlier the stiff end (outer ring or inner ring) of wind power bearing 1 is fixedlyed connected with base 2, then on certain mounting hole of the movable end (inner ring or outer ring) of wind power bearing 1, insert a pin 10, and connect a draw ring 50 at the front end of pulling force digital indicator 5, draw ring 50 is enclosed within on the pin 10, after connection finishes, open digital indicator 5, open air compressor then, this moment, the piston rod 41 of cylinder 4 began displacements, the wind power bearing 1 of installation begins to rotate, screen on the pulling force digital indicator 5 has reading to occur simultaneously, and writing down the highest torque value automatically, we judge whether the torsion of tested wind power bearing 1 reaches technical requirement according to these data.
Though toque force of wind power bearing equipment of the present utility model is relatively simple for structure, quite reasonable, practical, operate also easier.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
