Abstract
The invention discloses a large-size gear device. A gear is split into two semi-gears according to 180 degrees, wherein split surfaces are formed in the middle of the root of the gear; a part, about 1/10 flange thickness, from the root circle of the gear to the center direction of the gear, of each split surface is a contact surface of the two semi-gears, and the rest of the corresponding split surface is a non-contact stepped type clearance surface; each split surface is processed with four connecting bolt holes; the two end surfaces of the gear are respectively provided with a sealing convex ring; an oil return groove is formed in a position, close to a gear body, of the outer diameter of each sealing convex ring; a sealing wool felt is arranged on each of the two end surfaces of a gear cover in a matching manner; the sealing wool felts are in close contact with the outer diameters of the sealing convex rings on the gear. According to the large-size gear device disclosed by the invention, a gear sealing structure is more reasonable and better in sealing effect; lubricating oil is not easy to leak, intravasation of dust is isolated, and thus the service efficiency of lubricating oil is greatly improved and the service life of the gear is greatly prolonged.
Description
Technical field
The present invention relates to a kind of gearing for grinding machine class.
Background technique
In the grinding machine equipment that China produces present stage, because transmission gearwheel boundary dimension is very large, for the ease of transport, dismounting, two halves are generally all divided to make.But during two and half Gear combination, mating face is overall contact.Because the area of contact of entirety contact is large, during the assembling of two halves gear, on mating face easily there is residual gap in place, the pitch of gearwheel at mating face place is increased, when gear train runs, vibration, sled tooth and attachment bolt can be produced on mating face and loosen the phenomenons such as even fracture, affect the smooth running of gear train.Meanwhile, the sealing configuration of gear is also adopt traditional axial seal mode, and sealing effect is poor, easily occurs leakage of oil, enters the phenomenons such as dust, affects the service property (quality) of lubricant oil and the working life of gear, and it is very serious that Sealing also weares and teares.
Summary of the invention
Object of the present invention, is to provide the large gear device of a kind of advanced person, when two halves gear is assembled, more easily fit and fastening in mating face, eliminate joint clearance, more steady when gear train runs, gear life is longer, simultaneously, gear sealing configuration is more reasonable, and sealing effect is better, and lubricant oil not easily leaks outside, and isolated in dust and ooze, greatly improve the utilization efficiency of lubricant oil and the working life of gear.The technical solution used in the present invention is:
It comprises two and half side gears, two split surfaces of described two semicircular gears are bonded with each other, described split surface is arranged in the middle part of tooth root, described split surface is respectively the surface of contact of two halves gear and discontiguous step type clearance plane from tooth root toward Gear center direction, and described each split surface is all processed with coupling bolt hole.
Preferably, the wheel rim place of described gear both ends of the surface is equipped with a circle sealing bulge loop, and described sealing bulge loop external diameter has oil-return groove near denticle place.
Preferably, described surface of contact accounts for 10% of described split surface area.
Preferably, the gap length of described step type clearance plane is respectively 1mm, 0.4mm, 0.8mm from surface of contact to Gear center.
Preferably, described coupling bolt hole is 4, uses Bolt Connection respectively, and 1 bolt hole wherein near Gear center is finished bolt hole, is equipped with finished bolt, and all the other 3 is plain bolt hole, is equipped with plain bolt.
Preferably, described gear cover two exterior edge face is equipped with sealing wool felt, the sealing bulge loop external diameter close contact on described sealing wool felt and gear.
Beneficial effect of the present invention is: 1, step type mating face provided by the invention, and the mating face of two halves gear is small size contact, and during assembling, more easily fit and fastening in mating face, and eliminate joint clearance, during gear train operation more steadily, gear life is longer.
2, respectively there is a circle sealing bulge loop at gear both ends of the surface wheel rim place, sealing bulge loop external diameter has oil-return groove near denticle place, gear cover two exterior edge face is fixed with sealing wool felt with pressure ring, seal the sealing bulge loop external diameter close contact on wool felt and gear, form good radial seal, lubricant oil flow back into gear cover through oil-return groove, gear sealing configuration is more reasonable, sealing effect is better, lubricant oil not easily leaks outside, and isolated in dust and ooze, greatly improve the utilization efficiency of lubricant oil and the working life of gear.

Embodiment
Below in conjunction with figure, the invention will be further described, can implement according to this with reference to specification word to make those skilled in the art.
As shown in Figure 1 and Figure 2, gear cuts open dimidiation gear by 180 °, and split surface is opened in the middle part of tooth root, and split surface is the surface of contact of two halves gear toward flange thickness place, Gear center direction about 1/10 from root circle, and all the other are discontiguous step type clearance plane.
As in Figure 3-5, gap length is respectively 1mm, 0.4mm, 0.8mm from surface of contact to Gear center, each split surface is all processed with four coupling bolt holes, use 4 Bolt Connection respectively, 1 bolt hole wherein near Gear center is finished bolt 8, be equipped with finished bolt, all the other 3 is plain bolt hole 7, is equipped with plain bolt.Gear 1 both ends of the surface wheel rim place is all designed with a sealing bulge loop 5, and sealing bulge loop external diameter has oil-return groove 6 near denticle place.Gear cover 2 liang of exterior edge faces utilize bolt pressure ring 3 fixing seal wool felt 4, sealing wool felt 4 and the sealing bulge loop external diameter close contact on gear, form good radial seal, effectively prevent the dust outside gear cover from entering in gear cover, the lubricant oil on gear top flows to bulge loop 3 cylindrical by tooth root, and most of lubricant oil flow back into gear cover through oil-return groove 6.
Although embodiment of the present invention are open as above, but it is not restricted to listed in specification and mode of execution utilization, it can be applied to various applicable the field of the invention completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the present invention is not limited to specific details and illustrates here and the legend described.
