Description
Technical field
The utility model relates to hydraulic transmission, relates in particular to a kind of road roller hydraulic motor mounting structure.
Background technology
Vibratory roller is compared with static roller once the concern that common people occur causing immediately, and it has, and consolidation effect is good, the production efficiency advantages of higher, receives the always favor of vast unit in charge of construction more and more stricter today in workmanship and schedule requirement.
The associated mode driving device for hydraulic motor that adopts for hand guide double-steel wheel roller, road roller is when walking and vibration, hydraulic motor output shaft also will bear the radial load that whole road roller produces when bearing moment of torsion, thereby shortened the application life of hydraulic motor; Therefore need to provide a kind of road roller hydraulic motor mounting structure, when road roller walking and vibration, eliminate the radial pressure that hydraulic motor output shaft bears.
The utility model content
The technical problem that the utility model solves is: design a kind of road roller hydraulic motor mounting structure and eliminate the radial pressure that hydraulic motor output shaft bears.
For reaching this purpose, the utility model by the following technical solutions:
A kind of road roller hydraulic motor mounting structure comprises side plate and hydraulic motor carriage, and described side plate is fixed on the frame, and described hydraulic motor carriage is fixedly connected with and stretches into steel wheel inside with side plate, is provided with hydraulic motor in the described hydraulic motor carriage;
Described steel wheel becomes cylinder-like structure, be disposed radially dividing plate in it, described dividing plate center has circular hole, and the hydraulic motor flange is installed in the described circular hole, described hydraulic motor output shaft stretches in the hydraulic motor flange, and described hydraulic motor flange adopts key to be connected with hydraulic motor output shaft;
Be provided with the steel wheel pivot flange on the described hydraulic motor carriage, described steel wheel pivot flange is set on the hydraulic motor output shaft, is provided with bearing between described steel wheel pivot flange and the hydraulic motor flange.
Preferably, be provided with damper between described side plate and the frame.
Preferably, described hydraulic motor carriage is fixedly connected with side plate by bolt.
Preferably, described key connects the employing flat key.
Preferably, described hydraulic motor flange is bolted and is fixed on the dividing plate.
Preferably, described steel wheel pivot flange is bolted on the hydraulic motor carriage.
The beneficial effects of the utility model are: simple in structure, good damping effect, can eliminate the warp-wise power that hydraulic motor output shaft bears fully, a hydraulic motor output shaft output torque, no longer bear the alternation radial load from steel wheel rotates, vibrator vibrates and the road roller deadweight produces, therefore, improve to a great extent the application life of hydraulic motor, reached the road roller designing requirement.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is road roller hydraulic motor mounting structure schematic diagram described in the utility model.
Among the figure:
