Description
Technical field
The utility model relates to a kind of new gear.
Background technique
Gear transmission is most widely used a kind of type of belt drive in mechanical transmission, it is mainly used to the rotation motion of transmission two between centers, traditional dish cogged is integral gear, after long-term work uses, gear is often damaged, at this time just need to change the bad gear of point to ensure that machine runs well, and, general gear in use for some time, particularly in the use field that rotating speed is very high, wearing and tearing between this gear draw-in groove and axle can be very serious, cause the large minimizing of gear life, this is due to gear center of gravity and axis deviation, centrifugal force is produced during rotation, accelerate the wearing and tearing of draw-in groove, in addition, in transmission process, because the result of many factors comprehensive function produces noise, vibrate.Want stress release treatment, the normal method used, for optimizing design of gears parameter, optimizes profile of tooth; Or improvement manufacturing process, improve Gear Processing precision, reduce alignment error etc.; But it is large to improve difficulty, considerably increases design and manufacture cost.
Summary of the invention
It is simple that the technical problems to be solved in the utility model is to provide a kind of structure, cost-saving, for ease of maintenaince, wear-resistant, and the new gear of noise when effectively can reduce pinion rotation.
For solving the problem, the utility model adopts following technological scheme:
A kind of new gear, comprise gear body, described gear body is made up of the gear piecemeal that four shapes are consistent, the inner circle of described gear piecemeal is provided with texturizing layer, the side of described gear piecemeal is provided with engagement portion, the opposite side of described gear piecemeal is then provided with the groove corresponding with engagement portion, described four gear piecemeals are connected by engagement portion and groove buckle successively, during maintenance, dismounting is convenient and firm, do not need whole changing, cost-saving, described gear piecemeal is provided with circular trough, foam metal material has been filled with in described circular trough, noise is absorbed effectively, the lower end of described gear piecemeal is provided with fan-shaped casting lug thereon, the lower end of described fan-shaped casting lug thereon is provided with square hollow slot, gear is played the role of positioning, when preventing work, gear produces skew.
As preferably, described gear piecemeal is stainless steel gear piecemeal, durable convenient.
As preferably, described engagement portion is trapezium structure, and sound construction is stablized, and there will not be loosening situation.
As preferably, described four fan-shaped casting lug thereons composition circular ring type casting lug thereons, can increase the rotational strength of axis hole, make whole gear be easy to processing, and durable in use.
As preferably, described square hollow slot is arranged on the position of center line of gear piecemeal, is coordinated by axle, connects more firm.
As preferably, described circular trough is arranged on the central position of gear piecemeal, and absorbing vibration is more even, effectively can reduce noise during pinion rotation.
The beneficial effects of the utility model are: owing to being provided with gear piecemeal, gear piecemeal can arbitrarily combine, and make gear cost-saving when local damage, for ease of maintenaince; Owing to being provided with square hollow slot, wear-resistant, decrease the wearing and tearing of draw-in groove; Owing to being provided with circular trough and foam metal material, noise during pinion rotation effectively can be reduced.The lower end of described gear piecemeal is provided with fan-shaped casting lug thereon, can increase the rotational strength of axis hole, makes whole gear be easy to processing, and durable in use.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of new gear of the utility model.
Embodiment
Consult shown in Fig. 1, a kind of new gear, comprise gear body 1, described gear body 1 is made up of the gear piecemeal 2 that four shapes are consistent, after damage, only that piece of gear piecemeal 2 damaged need being replaced with new gear piecemeal 2 from entirety, making when changing the gear damaged convenient, quick.The inner circle of described gear piecemeal is provided with texturizing layer 7, is not needing, under the prerequisite of adding extra alloy, greatly to improve the intensity of teeth.The side of described gear piecemeal 2 is provided with engagement portion 3, the opposite side of described gear piecemeal 2 is then provided with the groove (not shown) corresponding with engagement portion 3, described four gear piecemeals 2 are connected by engagement portion 3 and groove buckle successively, engagement portion 3 firmly can withhold two gear piecemeals 2, make gear body more firm, described gear piecemeal 2 is provided with circular trough 5, foam metal material 6 has been filled with in described circular trough 5, when pinion rotation is subject to vibrating, effectively can be absorbed by foam metal material 6, thus reduce noise and vibration, the lower end of described gear piecemeal 2 is provided with fan-shaped casting lug thereon 7, described four fan-shaped casting lug thereons 7 form circular ring type casting lug thereon, the lower end of described fan-shaped casting lug thereon 7 is provided with square hollow slot 4, adopt four equally distributed square hollow slots 4, make center of gravity and the axis coinciding of gear, when High Rotation Speed, centrifugal force can not be produced, thus the wearing and tearing reduced between draw-in groove and axle.Described four fan-shaped casting lug thereons 7 form circular ring type casting lug thereon, can increase the rotational strength of axis hole, make whole gear be easy to processing, and durable in use.
Described gear piecemeal 2 is stainless steel gear piecemeal, and stainless steel serviceability is good.
Described engagement portion 3 is trapezium structure, and the engagement portion of trapezium structure has good buckle.
Described square hollow slot 4 is arranged on the position of center line of gear piecemeal 2, is coordinated by axle, connects more firm.
Described circular trough 5 is arranged on the central position of gear piecemeal 2.Absorbing vibration is more even, effectively can reduce noise during pinion rotation.
When using this gear, the gear that the formation one that first combined by four gear piecemeals 2 is complete, again by the cooperation of square hollow slot 4, gear is arranged on axle, in the process used, even if due to vibrations sounding, also can absorb via foam metal material 6, effectively can reduce noise during pinion rotation.
The beneficial effects of the utility model are: owing to being provided with gear piecemeal, gear piecemeal can arbitrarily combine, and make gear cost-saving when local damage, for ease of maintenaince; Owing to being provided with square hollow slot, wear-resistant, decrease the wearing and tearing of draw-in groove; Owing to being provided with circular trough and foam metal material, noise during pinion rotation effectively can be reduced.The lower end of described gear piecemeal is provided with fan-shaped casting lug thereon, can increase the rotational strength of axis hole, makes whole gear be easy to processing, and durable in use.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed in the new protection domain of this practicality and be as the criterion.
