Description
Technical field
The utility model relates to a kind of gear-box, particularly relates to a kind of gear-box being convenient to assemble.
Background technique
Because science and technology is more and more flourishing, the living standard of people is more and more higher, basic every household all has the means of transportation such as motorcycle or little sedan-chair automobile, the driving source of existing motorcycle or sedan car mainly comprises motor and engine composition, reduce rotating speed by speed reducer again and improve torsion, after speed reducer slows down, outputed power by the output shaft of speed reducer.Existing speed reducer general pitch wheel group or utilize worm screw and worm gear drive, in order to prevent speed reducer over-heat inside or wearing and tearing, can inject a large amount of lubricant oil in speed reducer, has reached the effect of cooling and lubrication.
When reality uses, be difficult to effectively prevent lubricant oil from overflowing by axle and shaft-cup hole because of oil pressure, thus cause the lubricant oil in speed reducer to run off, on the one hand, waste lubricant oil; On the other hand, due to the loss of lubricant oil, reduce the lubrication effect in acceleration machine, make the component in speed reducer easy to wear, thus shorten working life; Moreover existing speed reducer structure is complicated, not easily assembles.
Therefore those skilled in the art are devoted to develop a kind of gear-box being convenient to assemble.
Model utility content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide the gear-box being convenient to assemble.
For achieving the above object, the utility model provides a kind of gear-box being convenient to assemble, and comprises casing, input shaft and axle sleeve; Casing offers delivery outlet, and input shaft and axle sleeve are arranged in delivery outlet;
Output shaft is arranged with retainer ring, and the circumference along output shaft offers the first groove;
Input shaft is provided with ball bearing, and one end of ball bearing is provided with clasp, and clasp is arranged in the first groove;
Center line along axle sleeve offers perforation, and axle sleeve is set on input shaft by perforation, and ball bearing is arranged between input shaft and axle sleeve;
One end of axle sleeve is provided with flange, and the other end of axle sleeve is provided with clasp, and clasp is arranged in perforation, and the inwall of perforation is provided with the 3rd groove in the one end near flange;
The second seal ring is arranged with at the outer wall of axle sleeve.
For the ease of producing, saving procedure, simplified structure and guarantee fastness, retainer ring and input shaft are structure as a whole.
The beneficial effects of the utility model are:
1) loss of lubricant oil is effectively prevented;
2) working life of speed reducer is extended;
3) simplify the structure, easily assemble, reduce cost of production simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the sectional view after the utility model is installed.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Fig. 1 Fig. 2, a kind of gear-box being convenient to assemble, comprises casing 1, input shaft 4 and axle sleeve 2; Casing 1 offers delivery outlet 11, input shaft 4 and axle sleeve 2 are arranged in delivery outlet 11;
Output shaft 4 is arranged with retainer ring 41, retainer ring 41 and input shaft 4 are structure as a whole.Circumference along output shaft 4 offers the first groove 42.
One end input shaft 4 being arranged with successively the first seal ring 5 and ball bearing 6, first seal ring 5 offers the second groove 51; One end of ball bearing 6 is provided with clasp 7, and clasp 7 is arranged in the first groove 42;
Center line along axle sleeve 2 offers perforation 23, and axle sleeve 2 is set on input shaft 4 by perforation 23, and the first seal ring 5 and ball bearing 6 are arranged between input shaft 4 and axle sleeve 2;
One end of axle sleeve 2 is provided with flange 21, and flange 21 matches with the shell of casing 1, stops that external dust or foreign material fall into speed reducer.The other end of axle sleeve 2 is provided with clasp 24, and clasp 24 is arranged in perforation 23, and the inwall of perforation 23 is provided with the 3rd groove 25 in the one end near flange 21;
Circumference along axle sleeve 2 offers seal ring restraining groove 22; Be arranged with the second seal ring 3, second seal ring 3 at the outer wall of axle sleeve 2 and be arranged in seal ring restraining groove 22, carry out spacing by seal ring restraining groove 22 to the second seal ring 3, on the one hand, add the steadiness of the second seal ring 3, on the other hand, better can prevent oil seepage.
When assembling this device, first the second seal ring 3 of axle sleeve 2 outer wall is arranged in seal ring restraining groove 22, again ball bearing 6 is placed in perforation 23, now one end of ball bearing 6 contacts with clasp 24, subsequently clasp 7 is suitably being compressed, so that clasp 7 is placed in perforation 23, first seal ring 5 is placed in perforation 23, subsequently input shaft 4 is penetrated in perforation 23 by the first seal ring 5 through ball bearing 6, now clasp 7 is arranged in the first groove 42, first by axle sleeve 2, second seal ring 3, input shaft 4, a single unit system is formed together with first seal ring 5 forms with ball bearing 6, load in casing 1 at the device that will assemble, after installing, to be combined with casing 1 by flange 21 and to block outside, by axle sleeve 2, second seal ring 3, input shaft 4, the components such as the first seal ring 5 and ball bearing 6 are combined in advance, not only can improve the convenience of speed reducer when assembling, when needing to change or keep in repair at Long-Time Service when components such as input shafts, the entirety of assembling can directly disassemble from casing 1 by change, and do not need destruction first seal ring 5 or the second seal ring 3, just can change damaged part, reach the effect of assembly cost.
When speed reducer operates, the in-built lubricant oil of casing 1 because of input shaft 4 and other gear trains in casing 1 produce pressure change time, or during the oil pressure pressure produced because other group gear train frictions cause oil temperature to raise, when the situation that lubricant oil in casing 1 oozes out occurs, the first seal ring 5 and person second seal ring 3 is utilized to prevent lubricant oil from leaking, first seal ring 5 and person second seal ring 3 are installed in the utility model simultaneously, can effectively play double cutting off inflow effect, lubricant oil through the first seal ring 5 time, second groove 51 cross wall produces pressure, make outer of the first seal ring 5, improve the fastening force of perforation 23 inwall and retainer ring 41 thereof, make its first seal ring 5 and form good sealing effect between axle sleeve 2 and input shaft 4, reach the effect doubling to promote leakage proof.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technician in the art according to design of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
