Abstract
The invention discloses a gear contact coloring adjusting method of a heavy-duty vertical driving gear box. The key point is adjusting the radial gap between a sliding bearing together with a combination bearing and a main driving axle after centering two ends of the main driving axle so as to guarantee the approaching to the actual working condition during gearing coloring detection. The invention solves the influence of each manufacture error to the gear contact state, especially overcomes the coloring adjustment of the gear box, operating in an elastic vibration interruption, solves the problem of gear contact coloring fluctuation or coloring length insufficiency, simulates the most real gear engaging state, and thus, guarantees the greatest torque transmission capacity of a gear pair so as to improve the stability and accuracy of gear box operation and reduce the vibration noise. Additionally, the gear contact coloring provided by the invention is accurate in judgment and easy in adjustment.
Description
Technical field
The present invention relates to a kind of gear contacting and coloring adjustment method, particularly relate to a kind of method of adjusting with the heavily loaded vertical gearbox gear contacting and coloring of adjustable composite bearing.
Background technique
Domestic many Grand Equipments all begin production domesticization at present, and heavily loaded vertical driving gear case reliability is high, long service life, is used to the state key industry.The vertical high-precision heavy-load gear box transmission shaft of this class all adopts radial sliding bearing and axial thrust sliding bearing to support, and because the high request of spatial constraints and bearing life, sliding bearing begins to feel free to try and adopts floating type, adjustable combination bearing, combination bearing radially adopts adjustable many bearing shells location, axially adopt the thrust static-pressure sliding bearing to support, and thrust bearing is installed in the mechanism that supports with the dish spring.
The most important assembly precision of heavy-load gear box is to need to guarantee the gear pair contact precision.Because vertical driving gear case main transmission component is by dish spring mechanism supports, under slight rotation, just can produce elastic vibration, the design of radial sliding bearing radial clearance is larger in addition, main drive shaft will suffer in the gear installation place axial force F a1, Fa2 and radial force Fr1, Fr2, as shown in Figure 1, this must cause main drive shaft to produce beat.Therefore, must be according to the relevant parameter of the gear-boxes such as the diameter of main drive shaft, gear transmission moment size, rotating speed, when design, just must determine the beat amount δ 2 of the issuable beat amount of main drive shaft input end δ 1 and output terminal, and when assembling, measure accurately δ 1 and δ 2 values, as shown in Figure 2.
Traditional gear pair dye penetrant inspection is to test under unloaded or slight braking, thereby this will inevitably cause main drive shaft unstable the generations skew of shaft axis that cogs, the time of day that gear teeth face contacts in the time of therefore can't analog operation.If the gear pair contacting and coloring is bad, will cause the situations such as Gear Contact inequality, unbalance loading, extraordinary noise, severe patient causes the accidents such as broken teeth.
Therefore those skilled in the art be devoted to develop a kind of in the time can reflecting gear-box work the Gear Contact of the time of day of gear teeth face contact transfer painted adjusting method.
Summary of the invention
Because the defects of prior art, technical problem to be solved by this invention provides a kind of Gear Contact of the time of day that gear teeth face contacts in the time can reflecting gear-box work and transfers painted adjusting method.
For achieving the above object, the invention provides a kind of heavily loaded vertical driving gear case gear contacting and coloring adjustment method, may further comprise the steps:
(1) at main drive shaft initiatively gearwheel is installed; Output terminal at main drive shaft is installed combination bearing; At the combination bearing place scale adjusting screw rod is set; The adjustment fitting seat of driven pinion is placed on the casing, driven pinion is installed to adjusts on the fitting seat, and make driven pinion and initiatively gearwheel engagement;
(2) after being installed to main drive shaft on the casing, at input end and the output terminal of main drive shaft the tapering centring means being installed, and being made two tapering centring means between main drive shaft and casing;
(3) regulate the scale adjusting screw rod, to eliminate the radial clearance of combination bearing, the scale value of the scale adjusting screw rod that each bearing shell of record combination bearing is corresponding should be worth as reference value;
(4) remove the tapering centring means of input end, and keep input shaft steadily without rocking; Input end bush bearing inner ring is according to radial clearance size, by at sliding bearing inner ring adhering advertisment paper, the thickness of paster is not wait between the 0-0.16mm, to guarantee that radial clearance after bush bearing inner ring and the main drive shaft installation is as 0.02-0.04mm; Smear lubricating grease on the surface of paster after gluing paster, the casing bearing hole of then bush bearing being packed into, thus have good positioning main drive shaft;
(5) adjustment reduces the combination bearing radial clearance: by counterrotating scale adjusting screw rod, so that the radial clearance of combination bearing is controlled in the 0.04mm;
(6) according to velocity ratio, smear chilli oil at the active gearwheel flank of tooth, the interval number of teeth of smearing chilli oil on the gearwheel equates with the number of teeth of driven pinion;
(7) at the input end of main drive shaft barring gear is installed, at driven pinion deceleration loading device is installed, then continuously, at the uniform velocity, evenly input shaft is carried out jiggering, and to driven pinion apply continuously, at the uniform velocity, uniform load, with the interference of further elimination dish spring vibration;
When (8) the gear pair contacting and coloring does not meet the demands, the rotation driven pinion, the setting angle of change driven pinion, thus it is painted to adjust gear pair; After contacting and coloring is qualified, with the driven pinion fitting seat with casing hole, fraising, load onto locating stud, and use the bolton fitting seat.
Better, described tapering centring means comprises footstock; Be fixed with inner conical drogue by the first bolt on the described footstock; The cylindrical of described inner conical drogue cooperates with the endoporus of described footstock; The endoporus of described inner conical drogue is taper hole;
Be fixed with external conical sleeve by the second bolt on the described inner conical drogue; The cylindrical of described external conical sleeve cooperates with the endoporus of described inner conical drogue; The endoporus of described external conical sleeve can cooperate with main drive shaft.
Better, in the step (4), the radial clearance that makes sliding bearing inner ring and main drive shaft is 0.02-0.04mm.
The invention has the beneficial effects as follows: the inventive method has solved every foozle to the impact of Gear Contact state, especially overcome the painted adjustment that gear-box carries out under elastic vibration is disturbed, the difficult problems such as gear contacting and coloring fluctuation or painted length are inadequate have been solved, simulated the most real gear engagement states, guaranteed the maximum torque transmission capacity of gear pair, thus improved the gear-box running stationarity and precision, reduced vibration noise.And gear contacting and coloring accuracy of judgement of the present invention, adjustment are easily.
