Abstract
Description
本發明係關於一種具凸輪結構之舉刷裝置，尤指一種適用於繞線型馬達之舉刷裝置。The invention relates to a brushing device with a cam structure, in particular to a brushing device suitable for a winding type motor.
一般而言，於起動轉矩大的地方，如吊車、起重機、或礦區開採等需要大馬力機具之場所，其機具皆需採用繞線型馬達方能符合大馬力之需求。Generally speaking, in places where the starting torque is large, such as cranes, cranes, or mining areas, where high-powered machines are required, the machines need to be wound-type motors to meet the needs of high horsepower.
且繞線型馬達也因具有下述優點：可以利用二次起動電阻器降低起動電流、可以利用二次起動電阻器提高起動轉矩、所需開關容量小、起動過程較平滑、及可作小範圍控速，因而廣為產業界所使用。The winding type motor also has the following advantages: the starting current can be reduced by the secondary starting resistor, the starting torque can be increased by the secondary starting resistor, the required switching capacity is small, the starting process is smooth, and the small range can be used. Speed control is therefore widely used by industry.
習知繞線型馬達內部所需之舉刷機構，係採多連桿設計，而多連桿之設計方式，其整體機構之剛性及承載能力較低，大約僅能使用於最大電流400安培之繞線型馬達。且因其驅動方式係採多連桿連接帶動，於作動時，末端工作點處之位置精確度亦因而偏低，並非十分理想，尚有改善空間。The brushing mechanism required in the conventional winding type motor adopts multi-link design, and the multi-link design method has low rigidity and load carrying capacity of the whole mechanism, and can only be used for winding with a maximum current of 400 amps. Linear motor. Because the driving method is driven by multi-link connection, the position accuracy at the end working point is also low when it is actuated, which is not very ideal, and there is still room for improvement.
由上可知，如何達成一種簡化舉刷裝置之機構，提昇舉刷裝置之剛性，且減少其傳動損失，以有效提昇舉刷裝置之性能及承載力，進而使舉刷之作動精確且順暢，實是產業上的所迫切需要。It can be seen from the above how to achieve a mechanism for simplifying the brushing device, improve the rigidity of the brushing device, and reduce the transmission loss, so as to effectively improve the performance and bearing capacity of the brushing device, thereby making the brushing movement accurate and smooth. It is an urgent need in the industry.
發明人原因於此，本於積極發明創作之精神，亟思一種可以解決上述問題之「具凸輪結構之舉刷裝置」，幾經研究實驗終至完成本發明。The reason for the inventor's reason is that in the spirit of active invention and creation, a "brushing device with a cam structure" which can solve the above problems is considered, and the present invention has been completed after several research experiments.
本發明係有關於一種具凸輪結構之舉刷裝置，其係組設於一繞線型馬達內，舉刷裝置包括有：一馬達主軸、一滑環、一碳刷支架組、一驅動裝置、一傳動軸、一第一凸輪盤、及一第二凸輪盤。The present invention relates to a brushing device with a cam structure, which is assembled in a winding type motor. The brushing device comprises: a motor spindle, a slip ring, a carbon brush holder set, a driving device, and a driving device. a drive shaft, a first cam plate, and a second cam plate.
其中上述滑環係套設於馬達主軸外，滑環上組設有複數導電板，碳刷支架組係跨設於滑環上。另驅動裝置係固設於傳動軸之一端，驅動裝置並可帶動傳動軸旋轉。至於第一凸輪盤、及第二凸輪盤皆套設於傳動軸上，並一起連動。The slip ring system is sleeved outside the motor main shaft, and the plurality of conductive plates are arranged on the slip ring, and the carbon brush bracket group is spanned on the slip ring. The driving device is fixed on one end of the transmission shaft, and the driving device can drive the transmission shaft to rotate. As for the first cam disc and the second cam disc, they are sleeved on the transmission shaft and are linked together.
上述第一凸輪盤上組設有一第一連桿，且第一連桿上組設有一絕緣套筒，絕緣套筒上並組設有與滑環之複數導電板相對應之複數短路環。至於第二凸輪盤上則組設有一位於碳刷支架組下方之舉桿。The first cam plate is provided with a first connecting rod, and the first connecting rod is provided with an insulating sleeve, and the insulating sleeve is provided with a plurality of short-circuiting rings corresponding to the plurality of conductive plates of the sliding ring. As for the second cam disc, a lifting rod located below the carbon brush holder group is disposed.
其中，驅動裝置係能驅動傳動軸旋轉，使傳動軸旋轉角度位於一第一位置、及一第二位置。當傳動軸旋轉角度位於第一位置時，即傳動軸、第一凸輪盤、及第二凸輪盤位於原始位置，尚未旋轉，此時絕緣套筒上之複數短路環係未卡合於滑環上之複數導電板，且碳刷支架組也與滑環接觸，即繞線型馬達屬未短路狀態。Wherein, the driving device is capable of driving the rotation of the transmission shaft such that the rotation angle of the transmission shaft is at a first position and a second position. When the rotation angle of the transmission shaft is in the first position, that is, the transmission shaft, the first cam plate, and the second cam plate are in the original position, and have not been rotated, the plurality of short-circuit rings on the insulating sleeve are not engaged on the slip ring. The plurality of conductive plates, and the carbon brush holder group is also in contact with the slip ring, that is, the winding type motor is not short-circuited.
當傳動軸旋轉角度位於該第二位置時，即當驅動裝置帶動傳動軸旋轉至第二位置時，第一凸輪盤跟著旋轉一角度，帶動第一連桿滑移，進而促使絕緣套筒也跟著滑移，使複數短路環卡合於複數導電板。且第二凸輪盤同時跟著旋轉一角度，帶動舉桿滑移，進而促使碳刷支架組不與滑環接觸，使繞線型馬達處於短路狀態。When the driving shaft rotation angle is in the second position, that is, when the driving device drives the transmission shaft to rotate to the second position, the first cam plate rotates at an angle to drive the first link to slip, thereby causing the insulating sleeve to follow Slip, so that the plurality of short-circuit rings are engaged with the plurality of conductive plates. And the second cam disc rotates at an angle at the same time, causing the lift rod to slip, thereby causing the carbon brush holder group not to contact the slip ring, so that the winding type motor is in a short circuit state.
藉此，本發明可簡化舉刷裝置之機構，提昇舉刷裝置之剛性，並減少其傳動損失，因而可有效提昇舉刷裝置之性能及承載力，不僅可適用於大型之繞線型馬達，且可使舉刷之作動精確且順暢。Thereby, the invention can simplify the mechanism of the brushing device, improve the rigidity of the brushing device, and reduce the transmission loss thereof, thereby effectively improving the performance and the bearing capacity of the brushing device, and is applicable not only to a large winding type motor, but also It can make the brush move accurately and smoothly.

再者，上述第二凸輪盤可更組設一第二連桿，於第二連桿上再組設舉桿，俾使第二連桿可帶動該舉桿作上、下滑移。Furthermore, the second cam disc may further comprise a second connecting rod, and the second connecting rod is further provided with a lifting rod, so that the second connecting rod can drive the lifting rod to move up and down.
又，上述第一凸輪盤上之第一連桿可帶動絕緣套筒上之複數短路環作左、右滑移，俾可與滑環上之複數導電板對應卡合，使繞線型馬達處於短路狀態。Moreover, the first connecting rod on the first cam plate can drive the plurality of short-circuiting rings on the insulating sleeve to slide left and right, and the cymbal can be engaged with the plurality of conductive plates on the sliding ring, so that the winding type motor is short-circuited. status.

When the first position is away from the first position toward the second position, the second cam plate 24 is rotated at an angle. The second link 25 is caused to slide upward, thereby causing the lift rod 26 to slide upward (as shown in FIG. 6). The first cam plate 21 also drives the first link 22 to slide to the left, thereby driving the plurality of short-circuiting rings 231 on the insulating sleeve 23 to slide to the left (as shown in FIG. 7).

At this time, the transmission shaft 20 is already in the second position, that is, the second cam plate 24 has driven the second link 25 to slide upward until the lifting rod 26 completely lifts up the carbon brush holder group 13 so that the carbon brush holder group 13 does not The surface of the slip ring 11 is in contact (as shown in Figure 8). The first cam plate 21 also drives the first link 22 to slide to the left to engage the plurality of short-circuiting rings 231 on the insulating sleeve 23 on the plurality of conductive plates 110 on the slip ring 11, so that the winding-type motor is in a short-circuit state.
其中，本發明之第一、第二較佳實施例之第一凸輪盤21、及第二凸輪盤24之軌道設計，係先使第一凸輪盤21帶動第一連桿22滑移，使絕緣套筒23上之複數短路環231卡合於滑環11上之複數導電板110，使繞線型馬達處於短路狀態。隨後，第二凸輪盤24帶動第二連桿25向上滑移，使舉桿26向上完全舉起碳刷支架組13，使碳刷支架組13不與滑環11表面接觸。The track design of the first cam plate 21 and the second cam plate 24 of the first and second preferred embodiments of the present invention first causes the first cam plate 21 to drive the first link 22 to slip and insulate. The plurality of short-circuiting rings 231 on the sleeve 23 are engaged with the plurality of conductive plates 110 on the slip ring 11, so that the winding-type motor is in a short-circuit state. Subsequently, the second cam plate 24 drives the second link 25 to slide upward, so that the lift bar 26 completely lifts up the carbon brush holder set 13 so that the carbon brush holder set 13 does not contact the surface of the slip ring 11.
