Abstract
The utility model provides a stable and durable shaft structure, comprising a main shaft body, wherein an upper bearing and a lower bearing are arranged on the main shaft body; a shaft sleeve is sleeved on the main shaft body between the upper bearing and the lower bearing; a shell is arranged outside the main shaft body. The stable and durable shaft structure is reasonable in design, simple in structure, convenient to operate, stable in running and long in service life.
Description
Technical field
The utility model relates to a kind of steadily durable axle construction.
Background technique
In the industrial field, axle is a kind of common connection set, and axle is to be through in the middle of the bearing or the cylindrical object that wheel is middle or gear is middle, is square but small part is also arranged.Axle is the supporting rotational parts and turns round to transmit the mechanical parts of motion, moment of torsion or moment of flexure therewith, and it is shaft-like to be generally round metal, and each section can have different diameters, and the part of doing rotation motion in the machine just is contained on the axle.In the prior art, axle generally all is to be located between the bearing, and axle is easy to wearing and tearing in long-term using process, causes product short working life, and economic benefit is not high.Because existing above-mentioned shortcoming, it does not reach perfection inventor's thoughts, then exhausting the concentrated research of its intelligence overcomes, be engaged in this industry working experience for many years with it, and then develop a kind of simple and easy durable axle construction, utilize simple design, the effect that can make the utility model reach easy accessibility and increase the service life.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of steadily durable axle construction, and is reasonable in design, simple in structure, easy to operate, stable, long service life.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: a kind of steadily durable axle construction, comprise the main shaft axis body, described main shaft axis body is provided with upper bearing (metal) and lower bearing, be arranged with axle sleeve on the main shaft axis body between described upper bearing (metal) and the lower bearing, described main shaft axis body is provided with housing outward.
As preferably, described housing is provided with screw, is provided with the locking nut that housing and axle sleeve are connected and fixed in the described screw.By adopting this set, housing can be combined closely with axle sleeve, improve integrally-built stability.
As preferably, be provided with dustproof top cover on the described housing.By adopting this set, can prevent that dust etc. from falling in the housing.
As preferably, described main shaft axis body afterbody is provided with passive support lug.By adopting this set, bearing and the housing that is arranged on the main shaft axis body had the supporting effect of upwards lifting, prevent from skidding at the main shaft axis body, thereby influence the work effect.
As preferably, head and the afterbody of described main shaft axis body are respectively equipped with screw thread.By adopting this set, can guarantee to be connected with the reliable of adjacent parts, convenient for assembly, for convenience detach.
Beneficial effect:
The utility model adopts technique scheme that a kind of steadily durable axle construction is provided, and has remedied the deficiencies in the prior art, has prolonged the working life of main shaft axis body, improved economic benefit, reasonable in design, simple in structure, easy to operate, stable, long service life.
