Thickness is widened, and manufacturing cost is not only increased, and increases lid weight.
In addition the technique of casting itself there is the size surplus of blank, cause the increase of post-production amount, influence to cover
The cost of body.
Utility model content
The utility model is intended to provide a kind of reduction gearbox lid, whole to be processed using aluminum component, can reduce lid weight, together
When improved in structure, using design feature increase lid intensity so that lid weight reduce while will not shadow
Ring its structural strength.
To solve the above problems, a kind of reduction gearbox lid provided by the utility model adopts the technical scheme that
A kind of reduction gearbox lid, including lid, the lid are made of aluminium, and the lid is by straightway and circle
Segmental arc composition, the straightway are located at the side of the arc section, are fixedly connected with the arc section；The lid
It is internally provided with reinforcing rib, the reinforcing rib is consolidated along the radial distribution of the lid with the straightway and arc section
Fixed connection；Circular bar is provided on the reinforcing rib, the circular bar is located on the reinforcing rib, with the reinforcement
Muscle is fixedly connected, positioned at the inside of the lid.
Further, bearing hole is provided on the lid, the bearing hole setting no less than one is symmetrical
In the lid.
Further, the reinforcing rib is provided with multiple, and the inside of the lid is distributed in grid.
Further, power output axis hole is provided on the lid, the force-output shaft hole is located at the circular bar
Center, surrounding are fixedly connected with the reinforcing rib.
Further, oil sealing hole is provided with below the power output axis hole, the oil sealing hole runs through the power output
Axis hole.
Further, the oil sealing hole is internally provided with through-hole, and the through-hole runs through the oil sealing hole, connection
The power output axis hole.
Further, mounting hole is provided on the lid, the mounting hole is located on the side of the lid,
Through the lid.
Further, the mounting hole is provided with multiple, is distributed in the surrounding of the lid.
The utility model has the beneficial effects that: a kind of reduction gearbox lid provided by the utility model, by original cast iron
Material is changed to aluminium material, increases latticed reinforcing rib and circular bar on it, to guarantee the intensity of lid, on force-output shaft
Increase through-hole, guarantee lubricating oil can the sufficient lubrication between bearing and axis, reduce lid cost, improve the easy to use of lid
And efficiency.
