Disclosed is a strength-enhancing apparatus for a metal part comprising a recovery mechanism for sucking powder flow dust generated from glass beads crushed on a surface of a gear in a chamber to recover it together with drainage, wherein the recovery mechanism includes a liquid-spouting means arranged on a ceiling in the chamber, for effecting showering for the whole interior of the chamber. Accordingly, it is possible to reliably recover the mist containing the powder flow dust floating in the chamber, and it is possible to reliably avoid adhesion and accumulation of the powder flow dust.

An apparatus for simulating a ride on a vehicle has a base, and a simulated vehicle body which is supported on the base with a freedom of two-axis rotation about a rolling axis and a pitching axis. A pair of linear actuators are disposed in a position offset to one side in an axial direction of one of the rolling axis and the pitching axis, e.g., offset to one axial side of the rolling axis relative to the pitching axis. The actuators are disposed symmetrically relative to a plane which crosses the pitching axis at a right angle and which includes an axial line of the rolling axis. A fixing member and a movable member of each of the actuators are coupled to the base and the simulated vehicle body, respectively, through universal joints.

A set oil ring to be assembled into a piston ring groove is made up of a spacer ring and a pair of side rail rings to be placed on both sides thereof. In assembling one of the side rail rings into a first groove portion which is on an upper side of the spacer ring in the piston ring groove, a guide member, which can be moved up and down for fitting the rings onto a piston, is moved to a first fitting position which is substantially the same level as the groove wall surface of the first groove portion. A restricting member is disposed oppositely in front of the guide member while leaving a clearance facing the first groove portion. One of the side rail rings is pushed out of the front end of the guide member in a condition in which split end portions of the spacer ring are restricted by the restricting member so as not to overlap. In assembling the other of the side rail rings into a second groove portion, which is on the lower side of the spacer ring in the piston ring groove, the guide member is moved to a second fitting position in which the front end of the guide member becomes substantially equal in level to that surface of the spacer ring which is on the side of the second groove portion. The other of the side rail rings is pushed out of the front end of the guide member in a condition in which the split end portions of the spacer ring are restricted by an internal surface of the guide member so as not to overlap.

A multispindle-head machine tool has a column, a plurality of multispindle heads each having a plurality of tools and an engaging member and an annular feed passageway supporting the multispindle heads for circulatory movement therealong. The annular feed passageway includes a pair of upper and lower fixed guide members supported on the column, and a movable guide member movable back and forth horizontally for interconnecting ends of the upper and lower fixed guide members near a machining position. A rotary actuator is provided together with a feed mechanism disposed around the annular feed passageway and movable to circulate along the annular feed passageway by the rotary actuator for moving the multispindle heads along the annular feed passageway. An actuator unit is mounted on the column in association with the movable guide member for positioning one of the multispindle heads which is held on the movable guide member in the machining position, and rotating the tools of one of the multispindle heads. A jig table is mounted on a side of the column and horizontally movable back and forth. The jig table includes an attachment jig for supporting a workpiece to be machined by the tools of one of the multispindle heads.

A pallet with a workpiece mounted thereon is delivered on a pallet carriage, and transferred onto the table of a machine tool which has a different height from the pallet carriage. Lifting mechanisms on the pallet carriage are engaged by respective positioning members in front of the machine tool. The lifting mechanisms are actuated to lift the pallet carriage to position the pallet carriage for transfer of the pallet onto the machine tool table. The pallet is transferred from the pallet carriage onto the machine tool table, half of a predetermined stroke by a first transfer mechanism on the pallet carriage and the remaining half of the stroke by a second transfer mechanism on the machine tool table. The table has vertically movable support rollers for supporting the pallet when it is transferred onto and from the table. When the pallet P is positioned on the table, the vertically movable support rollers are retracted downwardly. When the pallet is transferred onto the machine tool table, clamp units on the machine tool table enter T-shaped slots defined in the lower surface of the pallet, and are actuated to clamp the pallet directly on the table. Since the workpiece on the pallet thus clamped is held in a low position on the machine tool table, the workpiece can be machined by a machining tool that can move freely in a wide space.

A process for measuring an unbalance of a torque converter, in which an outer member and an inner member of the torque converter are assembled, and oil is filled into the outer member to establish a condition similar to an actual service state of the torque converter. In this condition, the two members are rotated in unison. If the rotational speed of the torque converter reaches a measuring rotational speed, a plurality of measurements are conducted with the phase of the outer and inner members being varied between each measurement through a predetermined angle, thereby correctly detecting only an unbalance due to the outer member, with an unbalance due to the inner member being canceled from the results of the measurements. Cutting a balance weight having a weight sufficient to correct the detected unbalance from a metal tape and attached said cut balance weight to an outer periphery of the outer member of the torque converter at a given position by spot-welding or adhesive-bonding.

An inner member of a constant-velocity joint is continuously tilted with respect to an outer member thereof up to a maximum tilt angle while the inner member is rotating. From data including tilt angles and torques which are measured when the inner member is tilted, and also from maximum and minimum torque values at the maximum tilt angle which are detected from the measured data, there is calculated a pair of curves indicative of the maximum and minimum torque values of the inner member at the respective tilt angles. Maximum and minimum torque values at a given tilt angle of the inner member are then calculated from the calculated curves, and then compared with the predetermined reference values, thereby determining whether the constant-velocity joint is good or not.

Method of inspecting constant-velocity joint

An apparatus for machining a bevel gear has an apparatus frame, a spindle head provided on the apparatus frame for rotatably supporting a spindle on which a machining tool is mounted, and an indexing unit provided for holding a workpiece such that the workpiece is indexed by one pitch of teeth to be formed thereon to perform machining of tooth spaces with the machining tool. The spindle is horizontally and rotatably held on a spindle head such that the spindle is immovable in the axial direction of the spindle. The spindle head is movable back and forth in the axial direction and is movable in a lateral direction at right angles to the axial line. A column is provided on the apparatus frame in front of the spindle head such that the column is turnable about a vertical axial line at an arbitrary angle. The indexing unit is provided in a plurality of pieces on an external periphery of the column at a distance between each of the indexing units. The indexing units are provided on the column in a vertically movable manner. A plurality of vertically movable lifting frames are provided on the column at a distance therebetween in the circumferential direction of the column and the indexing units are detachably mounted on the column.
