Automatic assembling machine of needle roller of planet wheel

Abstract

The invention relates to an automatic assembling machine of a needle roller of a planet wheel, belonging to the technical field of automatic loading equipment of a needle roller bearing of a retainer. The automatic assembling machine comprises a stepping motor, an indexing disc, a first needle roller feeding device, an annular spacer feeding device, a second needle roller feeding device, a refillpart loading device, a planet wheel assembly part pushing-off device, and the like, wherein a fixed stand is provided with the indexing disc and the stepping motor; follower fixtures are uniformly distributed on the surface of the indexing disc; and a fixed installation plate positioned on the periphery of the indexing disc is provided with a planet wheel workpiece feeding device, the first needle roller feeding device, the annular spacer feeding device, the second needle roller feeding device, the refill part loading device and the planet wheel assembly part pushing device at intervals. In the invention, work units are controlled by a PLC (Programmable Logic Controller), and the automatic assembly of the needle roller of the planet wheel is realized, therefore, the assembling efficiency is enhanced and the problems that the traditional manual loading not only has low efficiency but also is easy to generate neglected loading and serious influences product quality are solved; and in addition, the production probability of unqualified products is reduced and the requirements on a product market are met.

Description

Technical field: [0001] The invention relates to an automatic assembly machine for planetary wheel needle rollers, which belongs to the technical field of automatic loading equipment for needle roller bearings without cages. Background technique: [0002] In the planetary gear transmission mechanism, when its volume becomes smaller and more compact, in order not to reduce the strength of the transmission, the original needle roller bearings are generally removed, and the needle rollers are directly installed in the planetary gear. As a bearing, it saves part of the space occupied by the original bearing cage and does not reduce the strength of its transmission. At present, most domestic manufacturers adopt the manual loading method in the needle roller assembly of the planetary wheel. The manual loading method consumes a lot of manpower and material resources. Not only is the work efficiency low and cannot meet the current market demand, but it is also prone to leakage. The...
