    摘要: A bevel gear unit comprising a bevel gear (11), a ball bearing (B.sub.1) coaxially mounted on the shaft of the bevel gear (11) and in contact with the back surface (17) thereof, a double spacer including an inner race spacer (12) and an outer race spacer (13) and mounted on the shaft of the bevel gear (11) behind the ball bearing (B.sub.1), ball bearings (B.sub.2, B.sub.3) mounted on the shaft of the bevel gear (11) behind the double spacer, and a bearing nut (15) screwed onto a threaded portion of the shaft of the bevel gear (11) behind the ball bearings (B.sub.2, B.sub.3). The axial length (l.sub.1) of the inner race spacer (12) is made smaller than the axial length (l.sub.2) of the outer race spacer (13) by a preloading allowance (.delta.), and the outer race spacer (13) is provided with threaded holes (t.sub.1) in the rear surface (f.sub.1) thereof. When applied to a mechanism having a plurality of coaxial bevel gears, particularly, to a wrist mechanism for an industrial robot, the bevel gear unit facilitates the preloading of the bearings.

    摘要: An apparatus for setting an industrial robot at the standard position comprises a block (19) to be measured, which is attached to a top end portion (18) of a wrist of the industrial robot, and a supporting member (23) for the measurement, which is attached to a fixing base (11) of the industrial robot. The block has three planes (20, 21, 22), orthogonal to one another, to be measured, and the block is positioned to the top end portion of the wrist so that the three planes to be measured are set at predetermined positions relative to the top end portion of the wrist. The supporting member has three frames (24, 25, 26) orthogonal to one another, and the supporting member is positioned relative to the fixing base so that the three frames take predetermined positions relative to three-axis orthogonal coordinates predetermined on the basis of the fixing base. By a plurality of dial gauges (27 through 32; 37 through 42), the positions of the planes of the block are measured. The dial gauges display predetermined values only when the planes to be measured of the block are set at predetermined positions relative to the frames of the supporting member.

    摘要: The industrial robot comprises a lower arm (13) provided on a robot body (12) pivotably about a first horizontal axis (C1). The lower arm (13) has provided thereon a forearm (14) pivotably about a second horizontal axis (C2). The forearm (14) is rotationally driven by a drive such as a motor (16). The robot body (12) has provided thereon a rotating disk (17) interlocked with the pivoting of the forearm (14) about the second axis (C2) and rotatable about the first axis (C1). Also the rotating disk (17) has secured thereon a first wheel (18) and coaxial therewith, the diameter of which is smaller than that of the disk. There is further provided a tension spring assembly (19) having one end thereof connected to the robot body (12) and which has rotatably mounted at the other end thereof a second wheel (21) having nearly the same diameter as that of the first wheel. Also provided is a chain (22) having one end thereof connected to the rotating disk (17) and the other end engaged on the first wheel (18). This chain (22) is engaged on the outer circumference of the second wheel (21) while pulling the tension spring assembly (19). The one end of the chain (22) is so disposed on the rotating disk (17) that when the upper end of the forearm (14) is directed normally downward, the chain portion (22b) between the rotating disk (17) and the second wheel (21) is substantially parallel to the chain portion (22c) between the first and second wheels (18) and (21).

    摘要: An apparatus for guiding a cable of an industrial robot having a support casing and a swivel casing axially supported by a swivel shaft bearing includes a cable guide. The guide has an end of an upper arm axially supported on a swivel axis inside the swivel casing, and an end of a lower arm axially supported on the swivel axis inside the support casing. A back column formed between the upper and lower arms guide passes through first and second arcuate cut-out portions provided in the swivel casing and support casing. A cable is passed from the support casing into the swivel casing along the cable guide back column, and moves proportionately to angular movement of the swivel casing.

    摘要: An apparatus for limiting range of motion of an industrial robot in accordance with the invention includes an indicating section (7) for indicating e.g. angles of rotation provided on a stationary side (1) of the swivel portion of an axis about which swiveling motion is possible. A range limiting member (6) having a dog and a stopper is movably disposed on the indicating section (7). When the industrial robot attempts to rotate beyond a stipulated range of rotation during operation, a limit member (81) provided on a movable side (2) of the axis portion contacts the dog (61) on the stationary side (1) to detect overtravel, whereby a warning is issued to the effect that the stipulated range of rotation has been exceeded. When the robot attempts to rotate further due to inertia, a shock absorber (82) strikes a stopper mechanism (62) to prevent excessive rotation.
