Abstract
The utility model relates to a gear pair of a speed reducer, and discloses a small-transmission-ratio spiral taper gear pair of a driving axle of a speed reducer. The gear pair comprises a gear shaft (1) and a spiral taper gear (2), wherein the gear shaft (1) comprises a shaft (11) and a bevel gear (12); and the bevel gear (12) is matched with the spiral taper gear (2). In the gear pair, the capacity of transferring torque between the gear shaft and the spiral taper gear and transmission efficiency are increased by reducing the transmission ratio between the gear shaft and the spiral taper gear.
Description
Technical field
The utility model relates to the reducer gear pair, has related in particular to a kind of retarder ransaxle close steps spiral bevel gear pair.
Background technique
Existing retarder Drive-Axle Gears auxiliary driving is bigger frequently, so transferring power is poor, and moment of torsion is little, and the gear of big speed ratio must adopt generating method processing, and processing speed is slow, and manufacturing efficiency is low, is not suitable for large-scale batch process.
Summary of the invention
The utility model is low at the secondary transmission efficiency of reducer gear in the prior art, shortcomings such as transferring power difference, provide the gear ratio of a kind of gear shaft and helical bevel gear more approaching, transferring power is effective, the retarder ransaxle close steps spiral bevel gear pair that moment of torsion is big.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Retarder ransaxle close steps spiral bevel gear pair comprises gear shaft and helical bevel gear, and described gear shaft comprises axle and umbrella gear, and umbrella gear cooperates with helical bevel gear.
As preferably, the number of teeth of described umbrella gear and the gear ratio of helical bevel gear are 2 ~ 2.5.Therefore processing speed is fast, and transmitting torque is big, the advantage that transferring power is effective.
As preferably, also be provided with tapped hole on the described gear shaft.
As preferably, described helical bevel gear is provided with positioning hole.By positioning hole is set, make helical bevel gear location when mounted convenient and accurate.
The utility model is owing to adopted above technological scheme, have significant technique effect: the utility model is by reducing the velocity ratio between gear shaft and the helical bevel gear, increase the ability of transmitting torque between gear shaft and the helical bevel gear, improved transmission efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The toponym that each number designation referred in the above accompanying drawing is as follows: wherein 1-gear shaft, 2-helical bevel gear, 11-axle, 12-umbrella gear.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing 1:
Embodiment 1
Retarder ransaxle close steps spiral bevel gear pair as shown in Figure 1, comprises gear shaft 1 and helical bevel gear 2, and described gear shaft 1 comprises axle 11 and umbrella gear 12, and umbrella gear 12 cooperates with helical bevel gear 2.
The gear ratio of the number of teeth of umbrella gear 12 and helical bevel gear 2 is 2 ~ 2.5, and present embodiment is a gear ratio 2.333.Therefore the gear ratio of the number of teeth of umbrella gear 12 and helical bevel gear 2 is controlled at 2.333, and it is big to have a moment of torsion, the advantage that transferring power is effective.
Also be provided with tapped hole on the gear shaft 1.Helical bevel gear 2 is provided with positioning hole.By positioning hole is set, make helical bevel gear location when mounted convenient and accurate.
In a word, the above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
