Description

行星曲轴传动机构及自行车Planetary crankshaft transmission mechanism and bicycle

技术领域Technical field

本申请涉及传动机构，尤其是行星曲轴传动机构；本申请同时提供使用行星曲轴传动机构的人力运动设备。The present application relates to a transmission mechanism, particularly a planetary crankshaft transmission mechanism; the present application also provides a human motion device using a planetary crankshaft transmission mechanism.

背景技术Background technique

在传统的内燃机中，通常都是通过曲柄连杆机构将活塞的往复运动转换为曲轴的旋转运动，进而由该曲轴驱动相应的运动部件，对外输出动力。在传统的压缩机中，也是通过曲柄连杆机构将曲轴的旋转运动转换为活塞的往复运动，对汽缸内的空气进行压缩。但是，由于这种曲柄连杆结构存在明显缺陷：内燃机和压缩机体积庞大、笨重且平衡性能差。因此，本领域技术人员在后来用具有偏心孔的圆形旋转块取代了连杆。这种机构使往复运动与旋转运动之间的转换得以简化，采用该转换机构的内燃机和压缩机相对于传统的内燃机和压缩机体积下降，重量减轻，且平衡性好。但根据目前的应用发现，采用具有偏心孔的圆形旋转块取代连杆的机构也有无法克服的明显缺陷，表现在：使用该结构的内燃机和压缩机，活塞冲程不能做得过大，否则，具有偏心孔的圆形旋转块半径相应的也会变得较大，导致摩擦功消耗较大，造成内燃机能量输出率较低或压缩机能量使用率较低，且会对轴承部件造成严重损坏，降低其使用寿命。In a conventional internal combustion engine, the reciprocating motion of the piston is usually converted into a rotational motion of the crankshaft by a crank-link mechanism, and the corresponding moving member is driven by the crankshaft to externally output power. In a conventional compressor, the rotary motion of the crankshaft is also converted into a reciprocating motion of the piston by a crank-link mechanism to compress the air in the cylinder. However, due to the obvious drawback of this crank-link structure: the internal combustion engine and the compressor are bulky, cumbersome and have poor balance performance. Therefore, those skilled in the art later replaced the connecting rod with a circular rotating block having an eccentric hole. This mechanism simplifies the transition between the reciprocating motion and the rotational motion, and the internal combustion engine and the compressor using the shifting mechanism are reduced in volume, weight reduction, and balance with respect to the conventional internal combustion engine and compressor. However, according to the current application, the mechanism of replacing the connecting rod with a circular rotating block having an eccentric hole has obvious defects which cannot be overcome. The performance of the internal combustion engine and the compressor using the structure cannot be excessively large. Otherwise, The radius of the circular rotating block with the eccentric hole will also become larger, resulting in a large frictional energy consumption, resulting in lower energy output rate of the internal combustion engine or lower compressor energy usage, and serious damage to the bearing components. Reduce its service life.

本申请的上述技术方案相比现有技术具有以下优点：The above technical solution of the present application has the following advantages over the prior art:

本申请提供的行星曲轴传动机构的其中一个方面，由于曲柄机构完全悬置于支撑臂上，曲柄机构与机体之间的摩擦只限于所述支撑臂与所述机体连接部分，因此，无论活塞行程导致支撑臂长度需要多大，曲柄机构与机体之间的摩擦不会发生明显变化，本申请节能环保，且经久耐用，维护成本低，非常适合于活塞冲程要求较大的情况。In one aspect of the planetary crankshaft transmission mechanism provided by the present application, since the crank mechanism is completely suspended on the support arm, the friction between the crank mechanism and the body is limited to the connection portion of the support arm and the body, and therefore, regardless of the piston stroke The length of the support arm needs to be large, and the friction between the crank mechanism and the body does not change significantly. The application is energy-saving and environmentally friendly, and durable, and has low maintenance cost, and is very suitable for a situation in which the piston stroke is required to be large.

本申请提供的行星曲轴传动机构的其中一个方面，由于采用支撑臂和支撑轴结构，可以通过在支撑轴上成形轮齿进行传动，也可以通过直接在支撑臂上成形轮齿进行传动，或直接将支撑臂做成电动机或发电机的转子进行传动，因此，本申请适用广泛，能根据不同使用要求进行灵活调整。One aspect of the planetary crankshaft transmission mechanism provided by the present application can be driven by forming the gear teeth on the support shaft by using the support arm and the support shaft structure, or by forming the gear teeth directly on the support arm, or directly The support arm is made into a rotor of an electric motor or a generator for transmission. Therefore, the present application is widely applicable and can be flexibly adjusted according to different use requirements.

本申请提供的行星曲轴传动机构的其中一个方面，由于左轴颈中心线与曲拐拐颈中心线的距离、左轴颈中心线与左支撑轴中心线的距离、右轴颈中心线与曲拐拐颈中心线的距离、以及右轴颈中心线与右支撑轴中心线的距离均相等，因此，本申请能够保证活塞在往复运动中所受侧向力为零。One aspect of the planetary crankshaft transmission mechanism provided by the present application is due to the distance between the center line of the left journal and the center line of the crank neck, the distance between the center line of the left journal and the center line of the left support shaft, and the center line and curve of the right journal. The distance between the center line of the abduction neck and the center line of the right journal is equal to the center line of the right support shaft. Therefore, the present application can ensure that the lateral force of the piston during reciprocation is zero.

本申请提供的行星曲轴传动机构的其中一个方面，由于曲轴，左支撑臂和右支撑臂都含有配重部分，因此，本申请能够最大程度的保证整个机体无振动。 In one aspect of the planetary crankshaft transmission mechanism provided by the present application, since the crankshaft, the left support arm and the right support arm all have a weight portion, the present application can ensure the vibration of the entire body to the greatest extent.
