A transmission mechanism includes a housing, a first rotating member accommodated in the housing and rotatable about a first rotating member axis, and a lubricating member accommodated in the housing and containing a lubricant. While the first rotating member rotates about the lubricating member, the lubricating member applies a preload to and comes into contact with a part of the first rotating member on the basis of an elastic force, so that the part of the first rotating member is lubricated with the lubricant.

A device for forming circumferential grooves in pipe elements uses multiple geared cam bodies mounted on a carriage which rotates about a fixed pinion. The gears engage with the pinion which causes the geared cam bodies to rotate relative to the carriage. Traction surfaces and cam surfaces on the cam bodies traverse the outer surface of the pipe element and impress a circumferential groove therein. To substantially prevent rotation of the pipe element the pitch circle diameter of the pinion equals the outer diameter of the pipe element and the pitch circle diameters of the traction surfaces equal the pitch circle diameters of the gears.

A rail assembly includes a track assembly defining an interior channel, a shuttle assembly received within the interior channel, and a carriage assembly coupled to the track assembly. The shuttle assembly includes a lock assembly. The carriage assembly includes a trigger assembly. The trigger assembly includes a trigger cam and an actuator cam coupled to the trigger cam. The actuator cam actuates the carriage assembly between locked and unlocked configurations relative to the track assembly.

The invention relates to mechanical engineering, and more particularly to devices for converting non-uniform rotational motion into uniform rotational motion and vice versa. A motion conversion mechanism comprises a housing, a common shaft, and a symmetrical differential reduction gear. The mechanism further comprises two rings for differential power flows, two cams having an inner working surface, and two cams having an outer working surface, and also two sliders with fingers. The profile of the cams having an inner working surface is described by the polar radius as a function of the polar angle and is an equidistant curve which is distanced outwardly from a first-order derivative of a basic closed curve by the size of the radius of a finger. The profile of the cams having an outer working surface is described by the polar radius as a function of the polar angle and is an equidistant curve which is distanced outwardly from a second-order derivative of a basic closed curve by the size of the radius of a finger. In a single revolution of the shaft, each ring performs two half revolutions back and forth. The result is a smooth operation.

The present invention provides a lubrication device for coating a lubricant onto the outer circumferential surface of a bearing. A lubrication device comprises a housing and a lubrication member that is accommodated within the housing. A bearing crosses and passes through the lubrication member so that an outer circumferential surface of the bearing comes into contact with an inner surface of the lubrication member, and due to this configuration, it becomes possible for the lubricant to be coated onto the outer circumferential surface of the bearing.
