摘要： PROBLEM TO BE SOLVED: To measure the loading weight of a machine whose load is changed with a stroke as the function corresponding to the stroke by detecting the change of a pressure, which is raised when the load is exerted on a moving ram and a sealed liquid is compressed. SOLUTION: When a loading weight F is received with a ram 3, a liquid inside a hydraulic cylinder 50 is compressed and the pressure is raised. The liquid pressure raising value is detected with a pressure detecting element 8 attached on the side face of the cylinder 1 through a liquid passage hole 1b and a detector 10 connected to the pressure detecting element 8 with a lead wire 9. The detected pressure value is sent further to a recorder 12 through a lead wire 11 and it is displayed or recorded. Therefore, the loading weight value is easily obtained.

摘要： PURPOSE: To obtain a press machine having the safety and the high operational ability by joining a pressure room of an auxiliary cylinder of a piston device and a pressure room of a knock out device with a hydraulic circuit. CONSTITUTION: The other end of a piston rod 17 composing a piston device acts following to the movement of a swinging plate 14 by engaging to an auxiliary cylinder 4b installed inside an intermediate plate 4, and applies the pressure onto the hydraulic oil sealed closely in the hydraulic circuit joining the pressure room of the auxiliary cylinder 4b and the knock out device 22. The knock out device 22 acts holding a definite relation to the rotation of a rotary inclining plate 12, and knocks out the pressed product from the die. The prevention of the breakage of machine caused by the excess reacting force generating in a time of galling of the pressed product with the die and the mechanical lock following the plastic deformation is made by escaping the abnormal pressure generating inside the hydraulic circuit in a time of galling until a set pressure with a relief valve 27.

摘要： PURPOSE:To reduce noise by forming a flange part for mounting a blower motor to an intake blower integrally with a motor cover part by means of resin. CONSTITUTION:A resin flange cover 10 is formed by forming a motor cover part 10b integrally with a flange part 10a. A blower motor 1 is pressed into a longitudinal rib 10c whose diameter is slightly smaller than the outer diameter of the blower motor 1, and housed and fixed into the the rib. A connector 2 of the blower motor 1 is fitted into a notch part 10c of the motor cover part 10b. Further, a cooling wind intake port 10g is mounted to the flange cover 10. The flange part 10a is fastened and fixed with screws to an intake blower case 50. By this constitution, the noise of the blower motor can be reduced.

摘要： PURPOSE:To prevent generation of smearing on the inner raceway of bearings and to improve the durability life by installing tapered rollers so that rollers in a 2nd and 3rd rows are longer than those in a 1st and 4th rows in a roll neck bearing for a rolling mill. CONSTITUTION:Roll neck bearing 9 provided with the outer race, inner race, and tapered rollers is fitted into the inside peripheral surface of a work roll chock 4 and a roll neck part 15 is fitted into the inside peripheral surface of the bearing 9. The body of a work roll is in contact with a backup roll; a roller length of tapered roller bearings 11, 12 of the bearing 9 at both ends in the longitudinal direction is shorter than that of bearings in the central part. smearing on inner raceways does not generated because a bearing inner race 13 performs rolling contact with tapered rollers 14 in the bearing 12 in a 1st row from the shaft end.
