Abstract
The utility model discloses a spiral bevel gear pair for an upper transmission box of an excavator. The gear pair comprises a driving gear and a driven gear which are of a spiral bevel structure, wherein the driving gear and the driven gear are meshed with each other, the end face of the driving gear, which is far away from a gear shaft, is of a concave spherical surface structure, the tooth spiral line of the driving gear rises from the low left corner to the upper right corner in an inclined manner, and the tooth spiral line of the driven gear rises from the lower right corner to upper left corner in an inclined manner, a shaft hole is arranged in the driven gear, and a spline is arranged at the inner side of the shaft hole. According to the utility model, as the end face of the driving gear, which is far away from the gear shaft, is of the concave spherical surface structure, on the condition that the driving gear is stressed equally, the steel raw material adopted in production and manufacture is effectively reduced, the manufacture cost is low, the manufacture process is simple, the driving gear and the driven gear are tightly meshed, the transmission smoothness is good, the noise is small, the occupied space of the driven gear is small, the structure is simple, and the conception is ingenious; therefore, the spiral bevel gear pair is convenient and practical and is suitable for popularization and use.
Description
Technical field
The utility model relates to mechanical transmission component manufacturing technology field, is a kind of technological improvement of excavator upper gear box spiral bevel gear pair specifically.
Background technique
Gear and gear product thereof are the important foundation parts of mechanized equipment, and the main transmission part of most complete set of machines all is gear transmission.Gear transmission is to use the widest a kind of mechanical transmission in the modern mechanical product.This is because it can guarantee constant velocity ratio, has advantages such as the transmission power scope is big, efficient is high, the life-span is long.
At present, the employed gear pair of excavator upper gear box is a spiral bevel gear pair, and the upper and lower end face of the driving gear in this spiral bevel gear pair is the vertical configuration structure; On big end face, be provided with integrally formed gear shaft, it is simple in structure, and is convenient and practical; Guaranteeing that the employed steel raw material of the driving gear of vertical configuration end face are more under the equal stressing conditions of driving gear, cost of production increases; Moreover driven gear takes up space greatly, and transmission efficiency is not high.Thereby design a kind of compact structure, and being skillfully constructed, cost of production is low, and manufacturing process is simple, and the excavator upper gear box spiral bevel gear pair little and that transmission efficiency is high that takes up space is the utility model design place.
Summary of the invention
The purpose of the utility model is the shortcoming that overcomes above-mentioned existing technology, and a kind of compact structure is provided, and is skillfully constructed, and cost of production is low, and manufacturing process is simple, and excavator upper gear box spiral bevel gear pair little and that transmission efficiency is high takes up space.
The utility model can be realized through following technological scheme:
The utility model discloses a kind of excavator upper gear box spiral bevel gear pair; Gear pair comprises the driving gear and the driven gear of wimble structure in the shape of a spiral, and driving gear and driven gear are meshing with each other, and described driving gear is the concave spherical surface structure at the end face away from gear shaft; Driving gear teeth helix is to upper right corner oblique ascension by the lower left corner; Driven gear teeth helix be by the lower right corner to upper left corner oblique ascension, offer axis hole in the driven gear, the axis hole inboard is provided with spline.
The utility model compared with prior art has following advantage:
The utility model adopts driving gear to be the concave spherical surface structure at the end face away from gear shaft, is guaranteeing under the equal stressing conditions of driving gear, and effectively reduce the steel raw material that adopted when manufacturing, cost of production is low; Manufacturing process is simple, and driving gear and driven gear engagement are tight, and transmission stability is good; Noise is little, and driven gear takes up space for a short time, and it is simple in structure; Be skillfully constructed, very convenient and practical, be fit to generally promote the use of.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Embodiment
To combine Figure of description to come the utility model is further described below:
Shown in accompanying drawing 1; Present embodiment discloses a kind of excavator upper gear box spiral bevel gear pair; Gear pair comprises the driving gear 1 and the driven gear 2 of wimble structure in the shape of a spiral, and driving gear 1 is meshing with each other with driven gear 2, and described driving gear is concave spherical surface structure 5 at the end face away from gear shaft; Driving gear teeth helix is to upper right corner oblique ascension by the lower left corner; Driven gear teeth helix be by the lower right corner to upper left corner oblique ascension, offer axis hole 3 in the driven gear, the axis hole inboard is provided with spline 4.
The utility model adopts driving gear to be the concave spherical surface structure at the end face away from gear shaft, is guaranteeing under the equal stressing conditions of driving gear, and effectively reduce the steel raw material that adopted when manufacturing, cost of production is low; Manufacturing process is simple, and driving gear and driven gear engagement are tight, and transmission stability is good; Noise is little, and driven gear takes up space for a short time, and it is simple in structure; Be skillfully constructed, very convenient and practical, be fit to generally promote the use of.
The above is merely the preferred embodiment of the utility model, is not the utility model is done any pro forma restriction; But the those of ordinary skill of all industry is all implemented the utility model with the above shown in the by specification accompanying drawing swimmingly; But all professional and technical personnel of being familiar with the above technology contents that is disclosed capable of using and a little change of making, modify the equivalent variations with differentiation in not breaking away from the utility model technological scheme scope, be the equivalent embodiment of the utility model; Simultaneously, all essence technology according to the utility model to the change of any equivalent variations that above embodiment did, modify with differentiation etc., all still belong within the protection domain of technological scheme of the utility model.
