摘要:
A bearing temperature monitoring device and bearing device provided with the monitoring device composed so that occurrence of scratch on the rotation shaft supported by the bearing caused by a bearing temperature carrying member integrated in the bearing such that its top end surface faces the rotation shaft, are provided. The bearing device is provided with a bearing temperature detecting device which comprises a bearing temperature carrying member made of material larger in thermal conductivity than the bearing layer and shaped to have a protruded part to be inserted slidably into a through hole in the bearing layer and a base part to be received in a cylindrical space in the back metal, the base part serving to restrict protrusion of the protruded part into the through hole so that the top end surface thereof is level with the sliding surface of the bearing layer, a pushing member attached to the back metal to push the temperature carrying member so that the member move toward the back metal against the pushing force of the pushing member when bearing load exerts on the temperature carrying member, and a temperature sensor for detecting temperature of the temperature carrying member.

A rotary impact tool includes a drive power source for producing rotational power, a drive shaft driven by the rotational power supplied from the drive power source, an output shaft operatively connected to the drive shaft for receiving the rotational power, an impact mechanism operatively couplable with the drive shaft. The rotary impact tool further includes a changeover unit for changing over an impact mode in which the impact mechanism is operated and a drill driver mode in which the rotational power produced by the drive power source is transferred to the output shaft without operating the impact mechanism and a multi-stage speed reduction mechanism for transferring the rotational power produced by the drive power source to the output shaft through the drive shaft at variable speeds in at least three speed modes including a low speed mode, a middle speed mode and a high speed mode.

A plurality of operation units connected in a pipeline structure performs an operation processing on data. A process control unit operates in synchronization with a system clock signal and generates a process control signal for controlling the operation units upon receiving a data notification signal that notifies the process control unit of an arrival of data from outside. A clock-control signal generating unit operates in synchronization with the system clock signal and generates a clock control signal for controlling a clock supply to each of the operation units upon receiving the process control signal.

An electric power tool includes a motor, a reduction mechanism, a driving unit, a bearing unit, a housing, a speed changing unit, a power switch, and an operation detecting unit which detects a reduction ratio changing operation performed by the speed changing unit to control electric power supplied to the motor. The reduction mechanism transfers the rotating power of the motor, and the driving unit transfers the rotating power of the reduction mechanism to a tip end tool. The bearing unit rotatably supports the driving unit, and the housing accommodates the motor, the reduction mechanism, the driving unit and the bearing unit. The speed changing unit changes a reduction ratio of the reduction mechanism, a power switch for turning on and off a power source of the motor.
