Description
Technical field
The utility model is related to gear transmission technology field, and in particular to the accurate precision gear of one kind transmission.
Background technology
In the prior art, gear drive is generally intermeshed realization transmission by the gear being arranged on not coaxial, directly with
The gear of motor output shaft connection is commonly referred to driving wheel, and driven pulley is referred to as with driving wheel meshed gears, driven pulley axle center
Power transmission shaft is driven shaft.Noise and undesirable vibration are easily produced when driving wheel and driven pulley are engaged in the prior art, is caused
Transmission is inaccurate.Particularly when gear long-term use occurs heavy wear, noise and vibration are stronger, it is impossible to meet essence
The really requirement of transmission.
The content of the invention
The purpose of this utility model is to provide a kind of accurate precision gear of transmission, technical problem to be solved be as
What reduces the noise and vibration produced when driving wheel and driven pulley engagement, improves the accuracy of transmission.
The accurate precision gear of transmission described in the utility model includes first gear, pinion and second gear, described
First gear and pinion are engaged with second gear, and multiple first gear teeth, institute are provided with the outer peripheral face of the first gear
State and be provided with the outer peripheral face of second gear multiple second gear teeth, multiple third rounds are provided with the outer peripheral face of the pinion
Tooth, first gear teeth are identical with the number of third round tooth, and first gear teeth and corresponding third round tooth align and position respectively
In on same straight line, the first distance between the tooth top of the adjacent third round tooth is less than adjacent first gear teeth
Second distance between tooth top.
The first gear and pinion are coaxially disposed, the position where the first central shaft of first gear and pinion
It is provided with bearing.
Described bearing is sleeve bearing.
Together with the first gear is bolted to connection with pinion.
The second gear has the second central shaft, and second central shaft is parallel to each other with the first central shaft.
The technical solution of the utility model has the following advantages that：
The accurate precision gear of transmission described in the utility model is simple and reasonable, can reduce when gear is engaged and produce
Noise and vibration, improve transmission accuracy.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram of the accurate precision gear of transmission described in the utility model.
Fig. 2 is the mesh schematic representation of the accurate precision gear of transmission described in the utility model.
Fig. 3 is the close-up schematic view of the accurate precision gear of transmission described in the utility model.
In figure, including：First gear 12, pinion 14, second gear 16, the first central shaft 17, bearing 18, the second center
Axle 22, first gear teeth 24, second gear teeth 25, third round tooth 26,.
Specific embodiment
Following examples are used to illustrate the utility model, but are not limited to scope of the present utility model.
As shown in Figure 1 to Figure 3, the accurate precision gear of transmission described in the utility model includes first gear 12, secondary tooth
Wheel 14 and second gear 16, the first gear 12 and pinion 14 are engaged with second gear 16, the first gear 12
Multiple first gear teeth 24 are provided with outer peripheral face, multiple second gear teeth 25, institute are provided with the outer peripheral face of the second gear 16
The number phase of multiple third round teeth 26, first gear teeth 24 and third round tooth 26 is provided with the outer peripheral face for stating pinion 14
Together, and first gear teeth 24 and corresponding third round tooth 26 align and be located on the same line respectively, the adjacent the described 3rd
The first distance 32 between the tooth top of the gear teeth 26 is less than the second distance 34 between the tooth top of adjacent first gear teeth 24.
The first gear 12 and pinion 14 are coaxially disposed, in first gear 12 and the first central shaft 17 of pinion 14
The position at place is provided with bearing 18.
Described bearing 18 is sleeve bearing.
The first gear 12 and pinion 14 are fixed together by bolt 142.
The second gear 16 has the second central shaft 22, and second central shaft 22 is mutually equal with the first central shaft 17
OK.
The accurate precision gear of transmission described in the utility model is due between the tooth top of the adjacent third round tooth 26
The first distance 32 less than the second distance 34 between the tooth top of adjacent first gear teeth 24, between effectively reducing gear
Gap, reduces noise and the vibration of engagement.First gear 12 and pinion 14 can also further be made in a preferred embodiment
Using the material of different hardness, such as first gear 12 uses metal material, pinion 14 to use nylon material, so that secondary tooth
Wheel 14 possesses more preferable elasticity, effectively reduces the vibrations between meshing gear, reduces the noise that engagement is produced.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
On the basis of the utility model, it can be made some modifications or improvements, this is to those skilled in the art apparent
's.Therefore, the these modifications or improvements on the basis of without departing from the utility model spirit, belonging to the utility model will
Seek the scope of protection.
