Abstract
The utility model relates to a bevel gear which comprises a large end (1) and a small end (2), wherein the small end (2) is added with a boss (2-1). The bevel gear added with the boss not only can improve the assembly efficiency, but also is prevented from being loosened due to the influence of gear engagement vibration in the working process, so that the transmission accuracy of the bevel gear is ensured; furthermore, the bevel gear has lower noise in the working process so as to be environment-friendly and durable.
Description
Technical field
The utility model relates to a kind of bevel gear, is specifically related to the bevel gear on a kind of car that is used to ride instead of walk.
Background technique
Bevel gear is the critical component of box of tricks, the bevel gear on car (car of especially riding instead of walk the old age) box of tricks that is used at present to ride instead of walk comprise big end and with hold capable small end greatly level with both hands.In the process that bevel gear and miscellaneous part with this structure assemble, need on small end, install a pad additional usually, to make the usefulness of pretension, therefore its efficiency of assembling is low, and pad that assembles and bevel gear are become flexible because of the gear engagement vibration in the process of work easily, thereby cause the transmission accuracy of bevel gear to reduce, and its noise in the process of work is also very big.
The model utility content
The purpose of this utility model provides a kind of bevel gear, and this bevel gear not only can be improved efficiency of assembling, and can not become flexible in the process of work.
The purpose of this utility model is achieved through the following technical solutions: a kind of bevel gear, comprise big end and small end, and described small end has additional boss, thus this bevel gear need not equipped pad and directly assembling, has saved the operation of assembling pad, improves efficiency of assembling.
Described boss is the circle ring column that fuses with described small end; The interior circle of described boss and bevel gear is projected as concentric circle same on axially, and the interior circular diameter of described boss equates with the interior circular diameter of bevel gear, so that assemble; Its outside diameter can come design arrangement according to specific requirement and structure.
The height value 1.6mm of described boss is good; Certainly it highly also can be set as the case may be.
The utility model has additional boss at the small end of bevel gear, and therefore, this bevel gear need not equipped pad in the process of assembling, has promptly saved the operation of equipped pad, thereby improves efficiency of assembling; The small end of above-mentioned boss and bevel gear fuses, so it can not be subjected to the influence of gear engagement vibration in the process of work, promptly can not become flexible because of the gear engagement vibration, thereby guarantee the transmission accuracy of bevel gear; The interior circle of above-mentioned boss and bevel gear is projected as concentric circle same on axially, so its stability of rotation in the process of work, and noise is little, and environmental protection is durable again.
Description of drawings
Fig. 1 is the plan view of bevel gear among the utility model embodiment 1.
Fig. 2 is the sectional view of bevel gear among Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but therefore the utility model is not limited among the following concrete mode.
Embodiment 1: as depicted in figs. 1 and 2, a kind of bevel gear comprises big end 1 and small end 2, has additional boss 2-1 on the described small end 2; Described boss 2-1 is the circle ring column that fuses with described small end 2; The interior circle of described boss 2-1 and bevel gear is projected as concentric circle same on axially, and the interior circular diameter of described boss 2-1 equates with the interior circular diameter of bevel gear; The height of described boss 2-1 is 1.6mm; Thereby this bevel gear has saved the operation of equipped pad in the process of assembling, improved efficiency of assembling, has prevented also that simultaneously it from becoming flexible because of the influence that is subjected to the gear engagement vibration in the process of work.
Claims (3)
1. a bevel gear comprises big end (1) and small end (2), and it is characterized in that: described small end (2) has additional boss (2-1).
2. bevel gear as claimed in claim 1 is characterized in that: described boss (2-1) is the circle ring column that fuses with described small end (2); The interior circle of described boss (2-1) and bevel gear is projected as concentric circle same on axially, and the interior circular diameter of described boss (2-1) equates with the interior circular diameter of bevel gear.
3. bevel gear as claimed in claim 1 or 2 is characterized in that: the height of described boss (2-1) is 1.6mm.
