Abstract
The utility model discloses an input gear shaft, comprising a main shaft. A large gear ring and a small gear ring are respectively arranged around the outer circles of the both ends of the main shaft; antirust layers are respectively arranged on the tooth top and the two side surfaces of each gear tooth of the large gear ring and the small gear ring as well as on the surface of the main shaft; location holes are formed in the both ends of the main shaft respectively; oil paths leading to a tooth groove between each two adjacent gear teeth in the large gear ring and the small gear ring are respectively formed at the both ends of the main shaft; and an annular groove is formed in the outer wall of the main shaft which is located on the inner side of the small gear ring. The input gear shaft is reasonable in structure and is prevented from rusting, so that the stability of the input gear shaft during a transmission process is improved; and the wear of the input gear shaft is alleviated, stress of the gear teeth during a rotation process is eliminated, and thus the service life of the input gear shaft is prolonged.
Description
Technical field
The utility model relates to the gear shaft field, specifically a kind of input gear axle.
Background technique
Gear shaft refers to support the mechanical parts that rotational parts also turns round to transmit motion, moment of torsion or moment of flexure therewith, presses the direction of transfer of power, and gear shaft can be divided into input gear axle and output gear shaft.The input gear axle is in the process of rotating, and the wearing and tearing of the large and small gear ring at its two ends are larger, and little gear ring can produce stress in rotation process, causes the gear teeth to produce distortion.In addition, the input gear axle is in the long-term work process, because the impact of environment, corrosion in various degree can appear in the surface of its main shaft and the gear teeth.
The model utility content
The purpose of this utility model provides a kind of input gear axle, and the surface of the crown of each gear teeth and bi-side and main shaft has respectively resin layer in the large and small gear ring, avoids the input gear axle phenomenon of corrosion to occur; The two ends of main shaft are respectively equipped with positioning hole, to improve input gear axle stability in transmission process; The two ends of main shaft are respectively equipped with leads in the large and small gear ring oil duct of teeth groove between adjacent two gear teeth, can inject lubricant oil to the surface of the gear teeth, to reduce wearing and tearing; The outer wall that is positioned at the main shaft of little gear ring inboard is provided with annular groove, the stress that produces in rotation process to eliminate the gear teeth.
The technical solution of the utility model is as follows:
A kind of input gear axle, include main shaft, two ends cylindrical around main shaft has respectively large and small gear ring, it is characterized in that: the surface of the crown of each gear teeth and bi-side and main shaft has respectively resin layer in the described large and small gear ring, the two ends of described main shaft are respectively equipped with positioning hole, the two ends of main shaft are respectively equipped with leads in the large and small gear ring oil duct of teeth groove between adjacent two gear teeth, and the outer wall that is positioned at the main shaft of little gear ring inboard is provided with annular groove.
The input gear axle of stating is characterized in that: described large and small gear ring includes respectively a plurality of rectangle gear teeth.
The beneficial effects of the utility model:
The utility model is rational in infrastructure, and the surface of the crown of each gear teeth and bi-side and main shaft has respectively resin layer in the large and small gear ring, has avoided the input gear axle phenomenon of corrosion to occur; The two ends of main shaft are respectively equipped with positioning hole, have improved input gear axle stability in transmission process; The two ends of main shaft are respectively equipped with leads in the large and small gear ring oil duct of teeth groove between adjacent two gear teeth, can inject lubricant oil to the surface of the gear teeth, reduce wearing and tearing; The outer wall that is positioned at the main shaft of little gear ring inboard is provided with annular groove, has eliminated the stress that the gear teeth produce in rotation process, has prolonged the working life of input gear axle.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, a kind of input gear axle, include main shaft 1, two ends cylindrical around main shaft 1 has respectively large and small gear ring 2,3, the surface of the crown of each gear teeth and bi-side and main shaft 1 has respectively resin layer 4 in the large and small gear ring 2,3, the two ends of main shaft 1 are respectively equipped with positioning hole 5, and the two ends of main shaft 1 are respectively equipped with leads in the large and small gear ring 2,3 oil duct 6 of teeth groove between adjacent two gear teeth, and the outer wall that is positioned at the main shaft 1 of little gear ring 3 inboards is provided with annular groove 7.
In the utility model, large and small gear ring 2,3 includes respectively a plurality of rectangle gear teeth.
Claims (2)
1. input gear axle, include main shaft, two ends cylindrical around main shaft has respectively large and small gear ring, it is characterized in that: the surface of the crown of each gear teeth and bi-side and main shaft has respectively resin layer in the described large and small gear ring, the two ends of described main shaft are respectively equipped with positioning hole, the two ends of main shaft are respectively equipped with leads in the large and small gear ring oil duct of teeth groove between adjacent two gear teeth, and the outer wall that is positioned at the main shaft of little gear ring inboard is provided with annular groove.
