Abstract
The invention relates to an expanding device, in particular to an expanding device used for narrow space. The expanding device aims at solving the problems that in the final assembly process of a speed reducer XH9 in the prior art, because the gap between an output shaft and a grade-II sun gear is too small, it is difficult to pull a supporting tool out of the gap when the whole speed reducer is turned to the horizontal state, and products are prone to damage. The expanding device comprises a first conical block, an expanding block, a second conical block, a cylinder and a threaded rod. The first conical block is a hollow conical sleeve body. The second conical block is a hollow conical sleeve body. The expanding block is a hollow sleeve body. A first conical hole is machined in one end of the expanding block, and a second conical hole is machined in the other end of the expanding block. An internal threaded hole matched with an external thread on the threaded rod is machined in one end of the cylinder. The threaded rod is sleeved with the first conical block, the expanding block and the second conical block. The cylinder is connected to the threaded rod in a threaded manner. The expanding device is used for the field of expanding in narrow space.
