Description
Technical field
The invention belongs to bearing detection technique field, relate to a kind of wind power used double row same diameter four point touching ball slewing bearing groove center distance tester.
Background technology
Along with the environmental pressure deficient relatively and that faced of traditional energy is increasing, makes various countries comprise and continue to increase input aspect the regenerative resource of wind-powered electricity generation in development.At present, wind-powered electricity generation industry each continent all over the world, and be quick growing trend.Particularly recent years, the development of global wind-powered electricity generation industry breaks with tremendous force, and the market demand growth trend of wind power equipment is good, and the development prospect of wind-powered electricity generation unit self-contained bearing presents one scene of flourishing life.The quick growth of wind-powered electricity generation industry is for the development of wind power equipment provides strong support.Over nearly 10 years, Chinese large-sized wind-powered electricity generation unit manufacturing industry starts from scratch, and begins to take shape at present.Particularly country has more put into effect some concrete industrialization support policies, and wherein proposing the wind power equipment localization rate of parts and components will reach more than 70%.Yet, owing to we start late, the research of wind power bearing is compared with external advanced enterprise have certain distance in addition, particularly aspect check, our gap is just bigger.
The wind power used double row same diameter four point touching ball turntable bearing is a kind of turntable bearing of brand new in China, it is the driftage bearing of high-power wind power generation equipment first-selection, because the requirement in 20 year serviceable life, it is less than 0 that the whole end-play of the type bearing requires, double channel play phase mutual deviation requires strict more, simultaneously, double channel play phase mutual deviation also directly has influence on the serviceable life of bearing.Present stage, owing to do not have the Internal and external cycle double channel ditch heart, often select for use numerically-controlled machine to guarantee or add ball to measure indirectly apart from direct measuring equipment, measuring error is bigger, is restricting the total quality level of the type bearing.
Summary of the invention
For solving wind power used double row same diameter four point touching ball slewing bearing groove center distance and the ditch heart apart from parallel error, the difficult problem that directly detects of mutual deviation mutually, the invention provides a kind of wind power used double row same diameter four point touching ball slewing bearing groove center distance tester, can effectively detect the wind power used double row same diameter four point touching ball slewing bearing groove center distance, can reflect ditch heart distance and the ditch heart intuitively apart from parallel error, whether mutual deviation satisfies the requirement of standard mutually, and the final double channel play of bearing phase mutual deviation be made accurately judge.
For achieving the above object, the present invention adopts technical scheme as described below:
Described wind power used double row same diameter four point touching ball slewing bearing groove center distance tester has the main support rod of measuring disk in order to be provided with, the top of described main support rod be provided with movable support rod and make movable support rod and main support rod hinged; One end of described movable support rod is fixedly connected with the measurement disk, constitutes the measurement disk structure that swings up and down of main support rod relatively on the movable support rod; The middle and lower part of described main support rod has the strip hole and is connected and fixed an end of bar by gib screw, the other end of described fixed bar is fixedly connected with the measurement disk, the structure that constitute that fixed bar can move along the strip hole of main support rod, the measurement disk on the fixed bar can be adjusted the position with fixed bar up and down; Be fastened on movable support rod one end the measurement disk, be fastened on fixed bar one end the diameter of measurement disk identical: the upper end of described main support rod connects to measure by the meter fixed bar use dial gauge, and the gauge outfit of described measurement usefulness dial gauge contacts with the other end of movable support rod.
Measuring instrument of the present invention can satisfy wind power used double row same diameter four point touching ball slewing bearing groove center distance and the ditch heart apart from the detection of mutual deviation mutually; Not only solved the direct measurement of ditch heart distance, more can reflect Internal and external cycle ditch heart distance and the ditch heart accurately, guaranteed the phase mutual deviation of the two ditch end-plaies after the final assembling apart from parallel error, mutual deviation mutually.

Among the figure: 1, measured workpiece, 2, measure disk, 3, movable support rod, 4, main support rod, 5, trip bolt, 6 meter fixed bars, 7, measure and to use dial gauge, 8, housing screw, 9, movable support rod pin, 10, gib screw, 11, fixed bar, 12, measure the disk trip bolt.
Embodiment
In conjunction with the accompanying drawings and embodiments the present invention is illustrated:
Embodiment:
As shown in Figure 1, 2: described wind power used double row same diameter four point touching ball slewing bearing groove center distance tester, have the main support rod 4 of measuring disk in order to be provided with, the top of described main support rod 4 be provided with movable support rod 3 and make movable support rod and main support rod hinged; One end of described movable support rod 3 is fixedly connected with measures disk 2, constitutes measurement disk 2 structure that swings up and down of main support rod relatively on the movable support rod; The middle and lower part of described main support rod 4 has the strip hole and is connected and fixed an end of bar 11 by gib screw 10, the other end of described fixed bar 11 is fixedly connected with measures disk 2, the structure that constitute that fixed bar 11 can move along the strip hole of main support rod, the measurement disk on the fixed bar can be adjusted the position with fixed bar up and down; Be fastened on movable support rod 3 one ends measurement disk 2, be fastened on fixed bar 11 1 ends the diameter of measurement disk 2 identical: the upper end of described main support rod 4 connects by meter fixed bar 6 to be measured with dial gauges 7, and described measurement contacts with the other end of movable support rod 3 with the gauge outfit of dial gauge 7.
The detection mode and the step of described wind power used double row same diameter four point touching ball slewing bearing groove center distance tester are as follows:
1, check and correction measuring instrument, the measuring workpieces ditch heart apart from the time, first check and correction measuring instrument, the check and correction size press the ditch heart apart from nominal size, adds measurement disk physical size;
2, survey ditch heart distance, after check and correction is finished, two measurement disks of detector are placed in two raceways of bearing respectively; Fixing fixedly rod end, move left and right activity rod end is read minimum value and is the ditch heart apart from actual measured value on indicator;
3, survey the workpiece ditch heart apart from parallel error, said method is measured a week, and the ditch heart is this workpiece ditch heart apart from parallel error apart from the difference of actual measurement maximal value and minimum value;
4, survey the cover bearing ditch heart apart from the phase mutual deviation, measure another supporting with it part lasso ditch heart distance then, the difference of two lasso ditch hearts distance is this cover bearing ditch heart apart from the phase mutual deviation.
5, select to measure disk according to the lasso of different channel shapes and curvature, the disk diameter is chosen the diameter of actual use steel ball, proofreads reference dimension again simultaneously and measures.
