Abstract
The utility model relates to a gear shaft, including the column body, the one end of column body is provided with the connecting axle, and the relative connecting axle other end of column body is provided with operates the end, the lateral surface of column body is provided with leads the oil groove, the both ends of leading the oil groove switch on the setting in the terminal surface at column body both ends respectively mutually. The utility model discloses technical scheme can add lubricating oil, and play lubrication action to gear shaft in leading the oil groove to reduce the friction of its during operation, prolonged life.
Description
Technical field
This utility model relates to a kind of gear shaft.
Background technology
Gear shaft, generally includes cylindrical body, and one end of described cylindrical body is provided with connecting shaft, and cylindrical body is provided with operation termination relative to the connecting shaft other end.Existing gear shaft, increases due to frictional force after long-term use, have impact on its service life.
Summary of the invention
The deficiency existed for prior art, the purpose of this utility model is the gear shaft providing a kind of simple in construction, increasing the service life.
For achieving the above object, this utility model provides following technical scheme: a kind of gear shaft, including cylindrical body, one end of described cylindrical body is provided with connecting shaft, cylindrical body is provided with operation termination relative to the connecting shaft other end, the lateral surface of described cylindrical body is provided with oil guide groove, and the two ends of the described oil guide groove end face respectively at cylindrical body two ends is conducted setting.
By using technical solutions of the utility model, lubricating oil can be added in oil guide groove, and gear shaft is played lubrication, thus friction when decreasing its work, extend service life.
This utility model is arranged further: one end, described cylindrical body respective operations termination is provided with positive stop lug boss, the external diameter of described positive stop lug boss is more than the external diameter of described cylindrical body, and the corresponding described oil guide groove position of described positive stop lug boss is provided with the oil-feed through hole being conducted with described oil guide groove.
By using technical solutions of the utility model, while positive stop lug boss plays gear shaft position-limiting action, can also the fit clearance of blocking teeth wheel shaft, prevent lubricating oil from being spilt by the fit clearance of gear shaft, and can carry out adding lubricating oil in oil-feed through hole easily.
This utility model is arranged further: be provided with connected unit between described cylindrical body and operation termination, and the external diameter of described connected unit is less than the external diameter of described cylindrical body, and described oil-feed through hole is placed in operation termination and falls in the perspective plane of cylindrical body.
By using technical solutions of the utility model, further improve the convenience adding lubricating oil in oil-feed through hole.
This utility model is arranged further: be provided with positioning boss between described connecting shaft and cylindrical body, and described connecting shaft correspondence positioning boss one end is provided with external screw thread.
By using technical solutions of the utility model so that gear shaft is easier for installation, work is more stable.

Detailed description of the invention
See accompanying drawing 1-accompanying drawing 2, gear shaft disclosed in this utility model, including cylindrical body 1, one end of described cylindrical body 1 is provided with connecting shaft 2, relative connecting shaft 2 other end of cylindrical body 1 is provided with operation termination 3, the lateral surface of described cylindrical body 1 is provided with oil guide groove 101, and the two ends of described oil guide groove 101 end face respectively at cylindrical body 1 two ends is conducted setting.By using technical solutions of the utility model, lubricating oil can be added in oil guide groove 101, and gear shaft is played lubrication, thus friction when decreasing its work, extend service life.
The present embodiment is arranged further: one end, described cylindrical body 1 respective operations termination 3 is provided with positive stop lug boss 4, the external diameter of described positive stop lug boss 4 is more than the external diameter of described cylindrical body 1, and corresponding described oil guide groove 101 position of described positive stop lug boss 4 is provided with the oil-feed through hole 401 being conducted with described oil guide groove 101.By using technical solutions of the utility model, while positive stop lug boss 4 plays gear shaft position-limiting action, can also the fit clearance of blocking teeth wheel shaft, prevent lubricating oil from being spilt by the fit clearance of gear shaft, and can carry out easily adding lubricating oil at oil-feed through hole 401.
The present embodiment is arranged further: be provided with connected unit 5 between described cylindrical body 1 and operation termination 3, and the external diameter of described connected unit 5 is less than the external diameter of described cylindrical body 1, and described oil-feed through hole 401 is placed in operation termination 3 and falls in the perspective plane of cylindrical body 1.By using technical solutions of the utility model, further improve the convenience adding lubricating oil at oil-feed through hole 401.
The present embodiment is arranged further: be provided with positioning boss 6 between described connecting shaft 2 and cylindrical body 1, and corresponding positioning boss 6 one end of described connecting shaft 2 is provided with external screw thread 201.By using technical solutions of the utility model so that gear shaft is easier for installation, work is more stable.
