An improved vibration proof suspension type vibrating roller is disclosed which includes a rolling roller rotatably supported in a frame structure, a hydraulic motor for rotating the rolling roller and a hydraulic motor for rotating a vibration generating shaft with an eccentric mass fixedly mounted thereon. A plurality of vibration proof members made of elastic material such as rubber or the like are fixedly secured to both the sides of the frame structure on the inner surface thereof. A hydraulic motor unit including a hydraulic motor for rotating the rolling roller, a plate axle and associated components is fixedly secured to one half member of vibration proof members, while a hydraulic motor unit including a hydraulic motor for rotating the vibration generating shaft, a support plate and associated components is fixedly secured to the other half number of vibration proof members. A bearing case rotatably mounted on the one hydraulic motor unit is bolted to one partition plate and a holder rotatably held in the other hydraulic motor unit is bolted to the other partition plate so that the rolling roller is driven by the one hydraulic motor via a planetary gearing reduction mechanism housed in the bearing case. The output shaft of the other hydraulic motor is connected directly to the vibration generating shaft via coupling means. |
