Abstract
The utility model discloses a new-type hydraulic walking motor for construction machinery and comprises a motor body and a planetary reduction gear. The rear part of the motor is connected with a gear structure that is connected with the body of the planetary reduction gear via a bearing. The utility model is characterized in that double rows of detachable angular contact ball bears are arranged between the motor body and the planetary reduction gear.
Description
Technical field:
The utility model relates to a kind of hydraulic moving motor.
Background technique:
Existing hydraulic moving motor, the axial dimension of running motor is big, and volume is big, connects with the gear structure that is connected with the planetary reducer body by standard rolling bearing at the motor body rear portion, and structure is not compact, and the work effect is undesirable.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the novel engineering machinery hydraulic moving motor of good working effect.
Technical solution of the present utility model is:
A kind of novel engineering machinery hydraulic moving motor, comprise motor body, planetary reducer, connect with the gear structure that is connected with the planetary reducer body by bearing at the motor body rear portion, it is characterized in that: biserial separable type angular contact ball bearing is set between motor body and planetary reducer.
Connect with the gear structure that is connected with the planetary reducer body by roller bearing at the motor body rear portion.
The utility model is rational in infrastructure, uses biserial separable type angular contact ball bearing structure, has reduced the axial dimension of running motor, and small product size and weight have been reduced about 20%, more is applicable to running mechanism.In motor configuration, adopt the roller rolling friction structure, make motor configuration compacter, make it to realize smoothly comprehensive functions such as rotation, deceleration, speed change, moment of torsion output.
Description of drawings:
Accompanying drawing is an embodiment's of the utility model a configuration diagram.
Embodiment:
A kind of novel engineering machinery hydraulic moving motor, comprise motor body 1, planetary reducer 2, connect with the gear structure 4 that is connected with the planetary reducer body by roller bearing 3 at motor body 1 rear portion, biserial separable type angular contact ball bearing 5 is set between motor body 1 and planetary reducer 2.The backhaul dish adopts surface treated spring material.
