    • A device in connection with a cutting machine with an annular saw blade and with a driving mechanism for off-center drive of the blade. The device includes two first rollers arranged to contact and roll against the web of the saw blade on one side of the blade and two second rollers arranged to contact and roll against the web of the blade on the other, opposite side of the blade. The first rollers are mounted on a first shaft, which is movable along a path against the plane of the saw blade, perpendicularly to the centerline of the shaft, for pressing the first rollers with a certain desired force against the blade web under counter force by the second rollers on the opposite side of the blade.

    • The invention relates to a hydraulic motor having a motor body comprising a first and a second part (71, 72) which are joined to each other in a parting plane (74). A motor chamber (2) with driving cogwheels (10, 11) is formed by borings (84, 85), which extend from the parting plane into a certain depth in at least one of the first and second parts (71, 72). A by-pass conduit (15) is provided between the inlet and outlet hydraulic conduits of the motor chamber. In the by-pass conduit there is provided a main valve (20) for closing and opening the by-pass conduit for starting and for stopping the hydraulic motor, respectively. The by-pass conduit is formed by portions (16, 17) of a first (100) and a second (101) connection between the parting plane (74) and the inlet conduit (5), and between the parting plane (74) and the outlet conduit (7), respectively, and by a cross link (18) between the first and second connections (100, 101).
    • 本发明涉及一种具有马达主体的液压马达,该马达主体包括在分型平面(74)中相互连接的第一和第二部分(71,72)。 具有驱动齿轮(10,11)的马达室(2)由钻孔(84,85)形成,该钻孔从分型平面在第一和第二部分(71,72)中的至少一个中延伸到一定深度。 旁通管道(15)设置在电动机室的入口和出口液压管道之间。 在旁通导管中设置有用于分别关闭和打开用于启动和停止液压马达的旁通管道的主阀(20)。 旁路导管由分离平面(74)和入口导管(5)之间的第一(100)和第二(101)连接部分之间以及分离平面(74)之间的部分(16,17)形成, 和出口导管(7)以及在第一和第二连接件(100,101)之间的交叉连杆(18)。
