  • Patent number: 11215254
    Abstract: To provide a vibration control bush that ensures improved durability of a rubber elastic body. An inner pipe film portion of the vibration control has an inclined surface whose inclination angle ? with respect to an axis O direction is set to one degree or more and less than three degrees, and the inner pipe film portion has an end portion in the axis O direction whose thickness dimension is set to a quarter or less of a dimension in an axis O perpendicular direction from an outer peripheral surface of an inner pipe to an apex of the protruding portion. This ensures reducing a rubber elastic body to deform so as to bend (close contact) between the inner pipe film portion and the outer pipe film portion when a load in a wrenching direction is input. Accordingly, a durability of the rubber elastic body can be improved.

  • Patent number: 11192761
    Abstract: A brake is operationally coupled by gear engagement to an axle of a device, whereby turning on the brake prevents the axle from rotating. Monitoring condition of the brake includes driving the axle of the device in a first rotation direction when the brake has been turned on. The axle of the device is driven in a second rotation direction when the brake has been turned on. A first position angle of the axle of the device, which follows from driving the axle of the device in the first rotation direction, is measured. A second position angle of the axle of the device, which follows from driving the axle of the device in the second rotation direction, is measured. A clearance of the gear engagement of the brake is determined on the basis of a difference of the first and the second position angles.
