Transmission structure

Abstract

The invention discloses a transmission structure comprising an input module, a speed change module and an output module; the input module comprises an input shaft, and the output module comprises an output shaft; the speed change module comprises a sliding guide sleeve, a gear shifting mechanism, a gear set and a transmission part, and the gear set comprises an outer gear and an inner gear which are meshed with each other; the sliding guide sleeve is sleeved with the input shaft, and provided with an ring groove and a key, and the gear shifting mechanism is clamped at the ring groove; the inner gear is provided with a first transmission hole, and the output module is provided with a second transmission hole; the transmission part is connected with the first transmission hole and the secondtransmission hole, and the outer gear is provided with a first inner hole comprising a first inner groove; and the output module is provided with a second inner hole comprising a second inner groove,and the key is in key connection with the outer gear through the first inner groove or in key connection with the output shaft through the second inner groove. The transmission structure disclosed bythe invention is compact and simple, low in cost, smooth in gear shifting, and convenient and reliable in speed change, and meanwhile the problems of gear collision, even gear breakage, are avoided.

Description

technical field [0001] The present invention relates to the technical field of transmission, and more specifically, relates to a transmission structure. Background technique [0002] Ordinary feeders generally provide limited gears, resulting in fewer speed segments. During the use of the feeder and wood processing, it is affected by various factors such as wood material, thickness, required processing shape, and cutting depth of the tool. Under the influence of factors, the user cannot accurately obtain the required speed segment, so it cannot meet the finer speed requirements required for processing. At present, users in the market will choose the feeder with frequency conversion speed regulation. This kind of feeder can realize stepless speed change within the selected range to meet the user's more precise speed requirements, but the cost of this kind of feeder is relatively high. Therefore, the market coverage is small, and there are not many users selected. [0003] T...

Problems solved by technology

However, the disadvantage of this variable-ratio coaxial transmission structure is that the overall structure is bulky and bloated, taking up a lot of space, and the gears are directly driven to mesh and disengage to switch gears, which may easily lead to problems such as poor fitting, tooth collision or even tooth collapse during the gear shifting process.
