Improved flywheel structure

Abstract

The invention provides an improved flywheel structure comprising a ratchet disc, a ratchet base and a ratchet block group, wherein the ratchet disc is provided with a series of ratchets; the ratchet base is correspondingly sleeved with the ratchet disc, the periphery of the ratchet base is provided with a plurality of ratchet block slots in which an inclined surface provided with spring bore slots are arranged, and the spring bore slots are provided with compression springs; the ratchet block group comprises a plurality of ratchet blocks embedded in the ratchet block slots and provided with ratchet supporting parts supported by the compression springs, and the ratchet block group is arranged on the ratchet base in an inequipotential angle. Therefore, the flywheel has continuous agility for transmission and has favorable instant transmission function; in addition, the compression springs are matched with limit of the ratchet supporting parts and the inclined surface so as to be firmly located in the spring bore slots without separating due to the up-and-down bounce, be firmer and more durable in running, greatly reduce faults and prolong the service life.

Description

technical field [0001] The invention relates to a ratchet gear structure, especially an improved flywheel structure with unequal-angle design, linkage agility, and a more stable and durable overall structure. Background technique [0002] The ratchet gear structure is widely used in various rotating transmission parts that need to operate in one direction, such as the flywheel structure. The existing flywheel structure 90 such as figure 1 , Figure 1A As shown, it includes a ratchet plate 91 and a ratchet seat 92 located at the center of the ratchet plate 91. The ratchet plate 91 is provided with a toothed plate 911 on the outer periphery and a series of ratchets 912 on the inner periphery. The ratchet seat 92 is provided with plural ratchet grooves 921 for setting plural ratchets 93, and the plural ratchets 93 are positioned on the ratchet seat 92 with a bunch of rings 94, and the ratchets 93 and the series of ratchets 912 are corresponding It is provided that the ratchet...

Problems solved by technology

Although this existing flywheel structure can complete the function of its one-way transmission, there are still some defects. When the ratchet 912 distance of 3 / 4 is arranged between the block 93 and the ratchet 912, the ratchet block 93 needs to advance the ratchet distance of this 3 / 4 and could be toothed (engaged) with the ratchet 912, due to the rotation ( idling) stroke is relatively large, so that the transmission seems not instant enough or slow, and the momentum is also relatively large, which will easily cause damage to the ratchet piece 93 and the ratchet 912

[0003] another example figure 2 , Figure 2A As shown, it is another existing flywheel structure 90A, which is mainly provided with a shrapnel groove 922 at the position opposite to the ratchet groove 921, and the shrapnel groove 922 is used to set a spring piece 95, and the spring piece 95 abuts against the ratchet piece 93, to replace the setting of the aforementioned beam ring 94, and the distance between each ratchet block 93 and the ratchet 912 has a different setting in a ratchet distance, so that the design of the ratchet block 93 unequal angle (position), It can reduce the distance and impact force of idling when turning, and improve the lack of the aforementioned existing flywheel structure 90; but because the shrapnel groove 922 and the ratchet groove 921 of this existing flywheel structure 90A are open spaces at the same position, making The spring piece 95 has the problem of being easily deformed and missing from the spring piece groove 922, which relatively affects its operational stability and service life, and is obviously not an ideal design.
