A turbine blade fitting apparatus for fitting multiple turbine blades radially to a disc having multiple disc grooves formed in its periphery. A blade preassembly is made by preassembling multiple turbine blades into a ring by connecting together their tips. The fitting apparatus has a second pedestal for temporarily placing the blade preassembly so that the upper face of the blade preassembly is higher than the upper face of a disc supported horizontally on a first pedestal. The second pedestal is lowerably supported by compression springs. Base parts of the blades are completely fitted into the disc grooves by the blade preassembly being pushed downward by a pushing mechanism while being vibrated.

Turbine blade fitting apparatus and fitting method

A wheel attached to a vehicle body via a suspension mechanism including an unsprung member is placed on and rotated by a rotating drum. A phase detector detects the rotational phase of the rotating wheel. A support table positioned adjacent the rotating drum is movable on three mutually perpendicular axes. A spring plate mounted on the support table is placed in resilient contact with a measuring surface of the unsprung member. The spring plate vibrates in response to vibration of the unsprung member in the longitudinal direction which in turn vibrates in response to wheel unbalance. A displacement detector on the support table includes a light source and light receiving elements which detect vibration of the spring plate caused by movement of the unsprung member in the longitudinal direction and thus detect wheel unbalance. Upon detecting wheel unbalance, a weight is selected which corresponds to the detected longitudinal amplitude of vibration of the unsprung member in accordance with a predetermined relationship between the longitudinal amplitude and the weight and the weight is attached to the rim of the wheel at an unbalanced point.

Wheel unbalance correction method and wheel unbalance detecting apparatus

A rack and pinion gearing comprising a helical rack and a spiral pinion. The rack has a structure defined by a radius, a distance from the axis to tooth crest, a helix angle, and a pressure angle determined from the viewpoint of applied kinematics so as to produce a balancing moment of rotation. The structure keeps the rack free from inclination and rocking about the axis which would otherwise result in a biting effect.
