Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1-Fig. 4, from scheming, can find out, the utility model lubricates reliable building material machinery special reduction gear, comprises input shaft 4, jack shaft 5 and output shaft, and input shaft, jack shaft and output shaft are arranged in casing by bearing.Described casing is surrounded and forms successively by top box 1, raising middle flask 2 and nowel 3 three parts, and the face of surrounding is designed to flange plate structure and connects by circumferential some bolts.Output shaft has three, is respectively output shaft I 6, output shaft II 7 and output shaft III 8; Input shaft 4, jack shaft 5 and output shaft I 6 are arranged in same level and by bearing between raising middle flask 2 and nowel 3 mould assembling faces, motor outputting power by input shaft 4 by a pair of gear transmission to jack shaft 5, jack shaft 5 arrives output shaft I 6 by two circular arc herringbone gears 9 by transmission of power, the spring bearing that jack shaft is corresponding is roller bearing, and input shaft, spring bearing corresponding to output shaft I are double-row conical bearing.Output shaft II 7 and output shaft III 8 the left and right sides symmetrical above output shaft I 6 and by bearing, be arranged on raising middle flask 2 and top box 1 mould assembling face between, output shaft I 6 is connected with output shaft III 8 with output shaft II 7 by overdrive gear simultaneously.According to special device requirement, two high speed output shafts need to be set, to meet building equipment requirement, so the application is using output shaft II 7 and output shaft III 8 as two high speed output shafts.
Described nowel bottom is formed with oil sump, on top box 1 surface, is provided with filling oil cover 10, and filling oil cover is connected by oiling pipeline and oil sump, and filling oil cover 10 is provided with the oil filling mechanism 11 for charging-up lubricant oil.In top box 1, be positioned at one jiao and be provided with Oil pump electrical machinery placement plate 12, Oil pump electrical machinery 13 is placed on Oil pump electrical machinery and places on plate 12, places plate corresponding position be provided with Oil pump electrical machinery case lid 14 to be opened/closed on top box 1 surface with Oil pump electrical machinery.In oil sump, be provided with the oil pump being connected with Oil pump electrical machinery, oil pump is connected with some nozzles by oil pipe, and arrangement of nozzles is used for gear to be lubricated to engaging gear small gear position at each.On all bearing supports, be provided with oilhole radially, oil pipe is communicated with each oilhole by branch line, for lubricating of bearing.
Described nowel 3 bottoms are provided with the swab case 15 communicating with nowel, and the side wall lower ends of swab case is provided with drain oil, be provided with and drain the oil with plug cock 16 on drain oil.At nowel 3 sidewalls, be provided with for observing the dipstick 17 of lubricants capacity.
The utility model is a kind of many output of single input special reduction gear that is specifically designed to building material machinery, mainly upper, middle and lower casing, input shaft, jack shaft, output shaft I, output shaft II, output shaft III and lubrication system, consists of.Motor outputting power by input shaft by a pair of gear transmission to jack shaft, then by two circular arc herringbone gears, power is delivered to output shaft I by jack shaft, simultaneously also by output shaft I by overdrive gear by part transmission of power to output shaft II and output shaft III.Due to the restriction of physical dimension, adopt involute gear can not meet power transmission requirement, therefore adopt double circular arc tooth system, this type gear when basic identical, has larger bearing capacity at size and involute gear.Because herringbone gear is had relatively high expectations to backlash, so the supporting way of jack shaft adopts and to have the roller bearing axially automatically regulating, and can realize the trace adjustment of axial clearance (running clearance).The variation in the engaging gear gap causing for the parallelism of each shaft axis, causes Contact Stress of Gear uneven, and this speed reducer adopts double-row conical bearing at the supporting way of input shaft, output shaft I.
