Anti-eccentric-wear roller type hydraulic tappet valve rocker arm combined device

The invention discloses an anti-eccentric-wear roller type hydraulic tappet valve rocker arm combined device which comprises a rocker arm shaft, a valve rocker arm, a hydraulic tappet, a roller and a valve bridge. The rocker arm shaft is sleeved with the valve rocker arm, and the valve rocker arm can swing with the rocker arm shaft as the axis. The hydraulic tappet is arranged at the end part of the valve rocker arm and can move along with the valve rocker arm. The roller is arranged at the lower end part of the hydraulic tappet and can move along with the hydraulic tappet. The valve bridge is arranged below the hydraulic tappet, the top of the valve bridge is provided with a contact plane, and the roller abuts against the contact plane, so that the valve bridge can move along with the hydraulic tappet. According to the anti-eccentric-wear roller type hydraulic tappet valve rocker arm combined device, the problems of eccentric wear and overturning of a valve can be finally solved by improving the stress point
