A gas turbine combustion chamber (8) surrounded by an inner wall (2) having cooling air bores (17) and an outer wall (9) that is spaced from the inner wall (2). The outer wall (9) likewise has cooling air bores (16) and is formed of a plurality of wall elements (11) that are arranged in the circumferential direction of the gas turbine combustion chamber (8) essentially next to each other. The outer wall elements are arranged on the inner wall (2) by means of a fixed bearing (24) on one narrow side (21) of a wall element and by means of a floating bearing (25) on an opposite narrow side (21) of the element, configured to define a hollow space (10) is formed between the two walls (2, 9).

The invention provides an automatic assembly machine (1), comprising an underframe (2) and a positioning device (8) used for an assembly head (6); wherein, the positioning device (8) is provided with a positioning arm (9) and a stabilizer stanchion (10); the positioning arm and the stabilizer stanchion can be arranged to move corresponding to the underframe (2) along the motion direction and can extend in a way that is crossed to the motion direction; furthermore, the positioning arm and the stabilizer stanchion have an interval with each other; the positioning arm (9) and the stabilizer stanchion (10) are respectively arranged by a fixed bearing (11) at an end range of the same side and by a loose end bearing (12) in the range of the other end correspondingly; furthermore, the stabilizer stanchion (10) and the positioning arm (9) are connected with each other rigidly only in the end ranges thereof.

The embodiment of the invention provides a grooving device for bearing production, and relates to the technical field of bearing machining equipment. The grooving device for bearing production comprises a rack main body mechanism, a cutting mechanism and a bearing inner ring fixing mechanism. The machine frame body mechanism comprises a bottom plate, a top plate and a supporting stand column, the top plate is arranged above the bottom plate, the two ends of the supporting stand column are fixedly connected to the bottom plate and the top plate respectively, and the cutting mechanism comprises a gear motor, a disc, a connecting rod, a guide rod, a cutter and a supporting limiting assembly. The gear motor and the supporting and limiting assembly are installed on the top of the bottom plate. The first chuck on one side of the back fixing assembly is used for fixing the bearing inner ring, and a cutter can conveniently cut the bearing inner ring into a groove. According to the bearing inner ring grooving device, the number of overall designed equipment assemblies is small, the bearing inner ring can be effectively grooved, the overall production cost is low, and good benefits can be brought to small-scale production.
