Description
Technical field
The utility model relates to gear, particularly a kind of gear of long service life.
Background technique
Gear makes wheel rim has tooth can engage the mechanical component transmitting motion and power continuously.Gear is the intermeshing mechanical parts having tooth of energy, and the application of gear in transmission has occurred very early.In 19 end of the centurys, generate cutting ratio juris and utilize the special purpose machine tool of this principle cutting and the appearance in succession of cutter, along with the development of producing, the stationarity of gear operation comes into one's own.
Gear also can be divided into cylindrical gears, bevel gear, noncircular gear, tooth bar, worm and worm gear by its profile; Spur gear, helical gear, herringbone gear, curved tooth cylindrical gear is divided into by tooth trace shape; External gear, internal gear is divided into by the surface at gear teeth place; Cast gear, cutting gear, rolling gear, sintered gear(s) etc. can be divided into by manufacture method.
The manufactured materials of gear and heat treatment process have a great impact the bearing capacity of gear and dimensional weight.Before the 1950's, the multiplex carbon steel of gear, the sixties uses alloyed steel instead, and the seventies multiplex case-hardened steel.According to hardness, the flank of tooth can divide into the soft flank of tooth and Hardened gear face two kinds.
The gear capacity of the soft flank of tooth is lower, but manufactures than being easier to, and running-in is good, is used for transmission size and weight without strict restriction, and in the common mechanical of limited production.Because in the gear of pairing, steamboat burden is heavier, and therefore for making the size working gear life-span roughly equal, steamboat tooth face hardness is generally than the height of bull wheel.
The bearing capacity of hardened face gear is high, and it is after gear essence is cut, then carry out quenching, surface hardening or carburizing and quenching process, to improve hardness.But in heat treatment, gear inevitably produces distortion, therefore must carry out grinding, grinding or essence after the heat treatment and cut, to eliminate the error because distortion produces, improve the precision of gear.
In existing gear transmission, gear is fixed by key with transmission shaft, when installation, the position regulation of gear, very inconvenient, and for some driving mechanism, need the position adjusting gear, to meet the different kinds of drive, therefore need a kind of easy for installation, the gear of easy to adjust and long service life.
Model utility content
The purpose of this utility model is the shortcoming overcoming prior art, the gear of the long service life providing a kind of structure simple, easy for installation and easy to adjust.
The purpose of this utility model is achieved through the following technical solutions: it comprises gear, the center of described gear offers axis hole, shaft hole sleeve is contained on main shaft, termination, the two ends radial direction of described axis hole extends to form two symmetrical ringfeder steps, ringfeder is set with in ringfeder step, described ringfeder is sleeved on main shaft, the exterior edge face of described ringfeder offers multiple tapped hole, screw is connected with in described tapped hole, described gear sidewall offers a pouring orifice, an oil groove and an annular oil duct is offered in gear, pouring orifice is communicated with oil groove, and oil groove is communicated with annular oil duct, one first oil leab is provided with bottom described oil groove, first oil leab extends to axis hole place, the sidewall of annular oil duct offers multiple second oil leab from inside to outside, second oil leab extends to the gear teeth place in gear.
Described tapped hole is evenly distributed on the circumferentially same of ringfeder exterior edge face.
The both ends of the surface of described gear offer a circular groove.
The second described oil leab is three, and the angle between adjacent two second oil leabs is 120 degree.
The utility model has the following advantages: gear of the present utility model, gear is offered two ringfeder steps, ringfeder is set with in ringfeder step, gear is by ringfeder locking main shaft, realize the synchronous axial system with main shaft, in the utility model, loosen, tighten screw, just can realize the locking of gear and loosen, thus make gear easy accessibility, position regulation convenient, and two ringfeders arranged, the high balance at two ends after gear is installed, avoid because of Gear tipping cause gear life to reduce phenomenon; Be provided with lubricant oil runner in gear, lubricant oil lubricated axis hole and the gear teeth, thus reduces the wearing and tearing of axis hole and the gear teeth, add the working life of gear.

Embodiment
Be further described the utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1, a kind of gear of long service life, it comprises gear 1, the center of described gear 1 offers axis hole 2, axis hole 2 is sleeved on main shaft 3, termination, the two ends radial direction of described axis hole 2 extends to form two symmetrical ringfeder steps 4, ringfeder 5 is set with in ringfeder step 4, described ringfeder 5 is sleeved on main shaft 3, the exterior edge face of described ringfeder 5 offers multiple tapped hole 6, screw 7 is connected with in described tapped hole 6, as shown in Figure 2, described gear 1 sidewall offers a pouring orifice 9, clogged by plug cock during pouring orifice 9 non-refuelling, as shown in Figure 3, oil groove 10 and an annular oil duct 11 is offered in gear 1, pouring orifice 9 is communicated with oil groove 10, and oil groove 10 is communicated with annular oil duct 11, one first oil leab 12 is provided with bottom described oil groove 10, first oil leab 12 extends to axis hole 2 place, the sidewall of annular oil duct 11 offers multiple second oil leab 13 from inside to outside, second oil leab 13 extends to the gear teeth place in gear 1.
In the present embodiment, described tapped hole 6 is evenly distributed on the circumferentially same of ringfeder 5 exterior edge face, thus when screw 7 is locked, and the power suffered by ringfeder 5 is balanced, makes ringfeder spreading even, thus increase ringfeder hold performance tightly.
In the present embodiment, as shown in Figure 2, for reducing the weight of gear 1, the both ends of the surface of described gear 1 offer a circular groove 8.
In the present embodiment, the second described oil leab is three, and the angle between adjacent two second oil leabs is 120 degree, thus makes lubricant oil can be evenly distributed in the surface of the gear teeth.
Working procedure of the present utility model is as follows: when gear 1 is installed, gear 1 is sleeved on main shaft 3 specified position, then two ringfeders 5 are set on main shaft 3, and make ringfeder 5 be positioned at ringfeder step 4, gear 1 is made to complete preliminary installation, then tighten the screw 7 on two ringfeders 5 simultaneously, make ringfeder 5 and main shaft 3 locking completely, and whole gear 1 symmetrically structure, so deliberately counterweight point need not be found, thus gear 1 is extremely convenient in whole disassembly process, use two ringfeders 5, avoid gear 1 and deflection occurs, thus affect working life, after installing, lubricant oil is added in pouring orifice 9, lubricant oil flows into oil groove through pouring orifice 9, and then flow into axis hole 2 and tooth surface respectively through the first oil leab 12 and the second oil leab 13, good lubrication is played to gear 1, thus the life-span of gear is increased.
