Abstract
The utility model discloses a gear with a simple structure. The gear with the simple structure comprises a gear body, wherein outer teeth are arranged on the outer side of the gear body, the number of the outer teeth is 30, the tooth profile angle of every two outer teeth is 12 degrees, thetip diameter of the gear body is 60 millimeters, the root diameter of the gear body is 45 millimeters, an axle hole is formed in the inner side of the gear body, and through holes are formed in the axle hole and the gear body. The gear with the simple structure is convenient to use and maintain, capable of saving cost and maintenance time and easy to apply and popularize.
Description
Technical field
The utility model relates to a kind of gear simple in structure.
Background technique
Having many uses of gear is the strength member in the various machinery, all will use various gears as the wrist-watch used in lathe, aircraft, steamer and the daily life, electric fan etc.The kind of gear is a lot, and spur gear wheel, cylindric spiral gear, spiral gear, straight toothed bevel gear, spiral bevel gear, worm gear etc. are arranged.Wherein use morely, also better simply is spur gear wheel, claims standard cylinder gear again.Parameters such as the formation of relevant gear involute, modulus, pressure angle will be introduced in relevant course.Here mainly introduce the processing method of spur gear wheel, the processing method of the form of gear tooth has two kinds.A kind of is forming method, utilizes the method that cuts out profile of tooth with the profiling cutter that is conformed to fully by the gear cutting machine slot form exactly, as mill teeth; Another kind is generating method, and it is to utilize being meshing with each other motion of gear cutting tool and driven gear and cut out the processing method of profile of tooth, as gear hobbing and gear shaping (demonstrating with hobboing cutter and slotting tool).Introduce the method that adds work gear with milling machine below.Gear is the intermeshing mechanical parts that tooth is arranged of energy, and its application in mechanical transmission and whole mechanical field is extremely extensive.O.004～100 millimeter modern gear technique reaches: module; Gear diameter is by 1 millimeter～150 meters; Transmitted power can reach 100,000 kilowatts; Change scooter hundreds of thousands rev/min; The highest peripheral velocity reaches 300 meter per seconds.The application of gear in transmission occurred very early.In first three more than hundred years Christian era, the Aristotle of Ancient Greece man has just set forth the problem with bronze or cast iron gear transferring rotational motion in " mechanical problem ".Ancient Chinese is for having used a whole set of train in the vehicle pointing to the south of model utility.
Gear is easily damaged parts, needs often to change, and when gear changing more, at first some other parts is pulled down, and just can replace, and causes the damage of miscellaneous part easily, has increased the cost of maintenance, and the maintenance trouble has prolonged the time of maintenance.
The model utility content
The purpose of this utility model is to provide a kind of gear simple in structure, has easy to usely, and it is convenient to repair, and provides cost savings, and has saved engineering time, is easy to application.
The technical solution of the utility model is: a kind of gear simple in structure, described gear simple in structure comprises gear body, the described gear body outside is provided with external tooth, the described external tooth number of teeth is 30, tooth-shape angle between each external tooth is 12 °, and the tip diameter of described gear body is 60 millimeters, and root diameter is 45 millimeters, described gear body inboard is provided with axis hole, and described axis hole and described gear body are provided with through hole.
In preferred embodiment of the utility model, the number of described through hole is 4.
In preferred embodiment of the utility model, described axis hole be shaped as rhombus or Octagon.
A kind of gear simple in structure of the present utility model has easy to usely, and it is convenient to repair, and provides cost savings, and has saved engineering time, is easy to application.
Description of drawings
Accompanying drawing 1 is the perspective view of the utility model gear simple in structure one preferred embodiment.
The mark of each parts is as follows in the accompanying drawing: 1, gear body, 2, axis hole, 3, through hole.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1, Fig. 1 is a kind of gear simple in structure of the utility model, described gear simple in structure comprises gear body 1, described gear body 1 outside is provided with external tooth, and the described external tooth number of teeth is 30, and the tooth-shape angle between each external tooth is 12 °, the tip diameter of described gear body 1 is 60 millimeters, root diameter is 45 millimeters, and described gear body 1 inboard is provided with axis hole 2, and described axis hole 2 is provided with through hole 3 with described gear body 1.
Further specify, the number of described through hole is 4, described axis hole be shaped as rhombus or Octagon.Because the existence of through hole, make that axis hole and gear body no longer are solid constructions in the past, the materials of single gear greatly reduce, reduced cost effectively, this gear structure is simple, and is easy to use, practical, connection between the gear wheel body is tightr, and matching gap is little, is easy to application.The utility model provides a kind of gear simple in structure, has easy to usely, and it is convenient to repair, and provides cost savings, and has saved engineering time, is easy to application.
Embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
