Description
本發明與減速器相關，尤指一種以諧波原理運作的減速器。 The invention relates to a speed reducer, and more particularly to a speed reducer that operates on the principle of harmonics.
電動自行車就其驅動電機而言，電機的額定轉速分為三類，即高速電機、中速電機和低速電機，電機額定轉速越高，其體積越小、重量越輕、效率越高、成本越低，但是一般電動自行車為低速運轉，如採用高速電機則需要配套減速器，減速器的減速比、體積、效率、成本是自行車驅動器性能、價格的決定性因素之一。目前電動自行車大多採用低速電機直接驅動，不需要機械減速機構，其技術含量低、效率低、成本高、體積大、重量重。近年來電動自行車已經大量採用中速電機，配套行星齒輪減速，性能有所提高。但目前綜觀國內外電動自行車還沒有採用高速電機，配套大減速比減速器作為電動自行車驅動器，限制了電動自行車的發展。 In terms of its driving motor, electric bicycles are classified into three categories: high-speed motors, medium-speed motors and low-speed motors. The higher the rated motor speed, the smaller the volume, the lighter the weight, the higher the efficiency, and the higher the cost. Low, but the general electric bicycle is running at low speed. If high-speed motor is used, the speed reducer is needed. The reduction ratio, volume, efficiency and cost of the reducer are one of the decisive factors for the performance and price of the bicycle driver. At present, most electric bicycles are directly driven by low-speed motors, and do not require a mechanical reduction mechanism. The technical content is low, the efficiency is low, the cost is high, the volume is large, and the weight is heavy. In recent years, electric bicycles have adopted a large number of medium-speed motors, and the planetary gears have been decelerated, and the performance has been improved. However, at present, the electric bicycles at home and abroad have not yet adopted high-speed motors, and the large reduction ratio reducers are used as electric bicycle drivers, which limits the development of electric bicycles.
一般電動自行車驅動器為設於自行車驅動軸的驅動電機，驅動器中置時，驅動電機通過鏈輪帶動自行車運行，驅動器也可前置或後置，從而帶動前輪或後輪轉動。通常驅動電機通過諧波減速器實現減速，滿足自行車的騎行要求。一般諧波減速器主要包括設於殼體內的諧波發生器、柔輪軸、諧波柔輪和諧波剛輪，驅動電機轉子與諧波發生器、柔輪軸、諧波柔輪和諧波剛輪同軸設置，諧波發生器一端連接驅動電機轉子，諧波柔輪一端通過軸承套接諧波發生器外圈，柔輪軸一端內圈通過軸承設於諧波 發生器另一端，柔輪軸軸徑外圈設於諧波柔輪軸徑段內圈，諧波柔輪軸徑段直接作為減速器的輸出軸驅動自行車前行。經實際使用，在自行車騎行一定公里數後，諧波柔輪的軸徑段發生斷裂，導致減速器故障，降低了減速器的使用壽命，且存在一定的安全隱患。究其原因，主要是諧波柔輪軸徑段應力集中、材料疲勞所致。因此傳統諧波減速器結構存在一定的缺陷。 Generally, the electric bicycle driver is a driving motor provided on the bicycle driving shaft. When the driver is placed in the middle, the driving motor drives the bicycle through the sprocket, and the driver can also be front or rear, thereby driving the front wheel or the rear wheel to rotate. Usually the drive motor is decelerated by a harmonic reducer to meet the cycling requirements of the bicycle. The general harmonic reducer mainly includes a harmonic generator, a flexible wheel shaft, a harmonic flexible wheel and a harmonic wheel set in the casing, and the rotor of the driving motor is coaxial with the harmonic generator, the soft wheel shaft, the harmonic soft wheel and the harmonic wheel. The one end of the harmonic generator is connected to the rotor of the driving motor, and one end of the harmonic flexible wheel is connected to the outer ring of the harmonic generator through the bearing, and the inner ring of one end of the flexible wheel shaft is set to the harmonic through the bearing. At the other end of the generator, the outer ring of the flexible wheel shaft diameter is set in the inner ring of the harmonic soft wheel shaft diameter section, and the harmonic soft wheel shaft diameter section directly drives the bicycle as the output shaft of the reducer. After actual use, after a certain number of kilometers of bicycle riding, the shaft diameter section of the harmonic flex wheel breaks, resulting in the failure of the reducer, reducing the service life of the reducer, and there are certain safety hazards. The reason is mainly due to the stress concentration of the harmonic soft wheel shaft section and the material fatigue. Therefore, the structure of the conventional harmonic reducer has certain defects.
本發明所要解決的技術問題是電動自行車驅動器的諧波減速器，本諧波減速器克服了傳統諧波減速器的缺陷，避免諧波柔輪軸徑段的斷裂，提高了減速器的使用壽命，保證了自行車的騎行安全。 The technical problem to be solved by the invention is the harmonic reducer of the electric bicycle driver. The harmonic reducer overcomes the defects of the traditional harmonic reducer, avoids the breakage of the harmonic soft wheel shaft diameter section, and improves the service life of the reducer. It ensures the safety of cycling.
