Multifunctional chain-free integration power output assembly for dense frame

Abstract

The invention discloses a multifunctional chain-free integration power output assembly for a dense frame. The multifunctional chain-free integration power output assembly comprises an output shaft, and further comprises a multifunctional complex conversion transmission device. The multifunctional complex conversion transmission device comprises a polygonal input shaft, a conversion reset gear mechanism arranged between the polygonal input shaft and the output shaft and a conversion control mechanism arranged between the conversion reset gear mechanism and the polygonal input shaft. The multifunctional chain-free integration power output assembly for the dense frame is simple, scientific and reasonable in structural composition, integrates speed change and brake locking and can achieve a variety of transmission functions, and the power input and output speed change transmission structure and method carried out on the same axis by the multifunctional chain-free integration power output assembly have high transmission efficiency.

Description

technical field [0001] The invention relates to a compact shelf. In particular, it relates to a multifunctional chainless integrated power output assembly of a compact rack. Background technique [0002] The existing compact shelf bookshelf, its lower shelf swing hand transmission device has always adopted the traditional chain transmission structure. Due to its transmission mode and corresponding transmission structure characteristics, this traditional chain transmission device has low relative transmission efficiency and low power. The transmission is weak. However, due to the unreasonable composition structure and corresponding transmission mode of the recently released chainless crank transmission device, it is impossible to realize the functions of speed change and brake lock at the same time, so that the brake lock and speed change mechanism of the compact rack need multiple devices to realize. , which will make the structure of the entire manual drive system of the ...

[0002] The existing compact shelf bookshelf, its lower shelf swing hand transmission device has always adopted the traditional chain transmission structure. Due to its transmission mode and corresponding transmission structure characteristics, this traditional chain transmission device has low relative transmission efficiency and low power. weak transmission

However, due to the unreasonable composition structure and corresponding transmission mode of the recently released chainless crank transmission device, it is impossible to realize the functions of speed change and brake lock at the same time, so that the brake lock and speed change mechanism of the compact rack need multiple devices to realize. , which will make the structure of the entire manual drive system of the compact rack huge and complex, with low operating efficiency, high relative energy consumption, low reliability and stability, large transmission noise, short service life, high failure rate in operation, and maintenance and repair work. large

However, some crank-hand variable speed transmissions realize the speed change by pushing and pushing the crank handle, which has a fatal flaw, that is, radial displacement will occur. When shaking, the gears will move unnecessarily, resulting in the corresponding gears Stuck or skipped teeth, preventing the power transmission from operating properly
