Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
A kind of heavy-load vertical uni-drive gear box gear contacting and coloring adjustment method, comprises the following steps:
(1) initiatively gearwheel 5 is installed on main drive shaft 9; At the output terminal of main drive shaft 9, combination bearing 2 is installed; At combination bearing 2, place arranges scale adjusting screw rod 3; The adjustment fitting seat 7 of driven pinion 6 is placed on casing 8, driven pinion 6 is installed on adjustment fitting seat 7, and driven pinion 7 is engaged with active gearwheel 6, as shown in Figure 3;
(2) main drive shaft 9 is installed to after on casing 8, at input end and the output terminal installation tapering centring means of main drive shaft 9, and make two tapering centring means between main drive shaft and casing, even if the tapering centring means at main drive shaft 9 two ends plays bearing;
(3) regulate scale adjusting screw rod 3, to eliminate the radial clearance of each bearing shell of combination bearing and main drive shaft, the scale value of the scale adjusting screw rod that each bearing shell of record combination bearing is corresponding, using this value as reference value;
(4) remove the tapering centring means of input end, and keep main drive shaft steadily without rocking; Input end bush bearing inner ring 1 is according to radial clearance size, by at sliding bearing inner ring adhering advertisment paper 11, the thickness value scope of paster is for being greater than 0 and being less than or equal to 0.16mm, with ensure bush bearing inner ring and main drive shaft install after radial clearance for 0.02-0.04mm, as shown in Figure 4; Glue the surface smear lubricating grease at paster after paster, then bush bearing is loaded casing bearing hole, thus main drive shaft of having good positioning;
(5) adjustment is to reduce combination bearing radial clearance: by counterrotating scale adjusting screw rod, make the radial clearance of combination bearing control in 0.04mm;
(6) according to velocity ratio, smear chilli oil at the active gearwheel flank of tooth, the interval number of teeth of gearwheel being smeared chilli oil is equal with the number of teeth of driven pinion;
(7) at the input end of main drive shaft 9, barring gear 12 is installed, driven pinion 6 is installed deceleration loading device 13, then continuously, at the uniform velocity, evenly jiggering is carried out to main drive shaft 9, and driven pinion 6 is applied continuously, at the uniform velocity, uniform load, to eliminate the interference of disc spring vibration further;
(8) when gear pair contacting and coloring does not meet the demands, rotate driven pinion 6, thus change the setting angle of driven pinion, namely change the shaft axis of driven pinion, and then it is painted to adjust gear pair; After contacting and coloring is qualified, driven pinion fitting seat 7 is holed together with casing 8, fraising, load onto locating stud 10, and use bolton fitting seat, as shown in Figure 8.
In the present embodiment, as shown in Figure 6 and Figure 7, tapering centring means comprises footstock 15, and footstock 15 is fixed with inner conical drogue 16 by the first bolt 17, the cylindrical of inner conical drogue 16 and the inner hole of footstock 15, and the endoporus of inner conical drogue 16 is taper hole.Inner conical drogue 16 is fixed with external conical sleeve 14 by the second bolt 18, and the cylindrical of external conical sleeve 14 and the inner hole of inner conical drogue 16, the endoporus of external conical sleeve 14 coordinates with main drive shaft 9.
In step (5), combination bearing each piece of bearing shell scale is determined after regulating and being judged by shaft axis analysis, and as shown in Figure 5, concrete regulated value is δ 3=(δ 1+ δ 2)/2, wherein δ 1 is the design beat amount of main drive shaft input end, and δ 2 is the design beat amount of output terminal.If Spur Gear Driving, then the shaft axis of main drive shaft will not produce skew, and built-up shaft each piece of bearing shell adjustment amount is identical.
In step (6), chilli oil must uniformly on active gearwheel one week be smeared, and namely the interval number of teeth is equal with the driven pinion number of teeth, and be convenient to detect initiatively gearwheel and whether there is contacting and coloring fluctuation, this is the key judging painted fluctuation.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technician in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment.
