一种减速箱、减速电机及制冰机负载部分与减速电机连接结构A reduction box, a reduction motor, and a connection structure between a load part of an ice maker and a reduction motor 技术领域Technical Field

螺旋式制冰机构的冰钻需搭配减速电机使用,通过减速电机为冰钻提供自转的动力,通常会将整个螺旋式制冰机构固定在减速电机的减速箱输出端,通过螺栓将冰钻支架固定在减速电机的减速箱壳体上,并通过联轴器实现冰钻与减速箱输出轴的同轴联动。The ice auger of the spiral ice-making mechanism needs to be used with a reduction motor, which provides the ice auger with power for self-rotation. Usually, the entire spiral ice-making mechanism is fixed to the output end of the reduction motor's reduction box, and the ice auger bracket is fixed to the reduction box housing of the reduction motor by bolts, and the coaxial linkage between the ice auger and the reduction box output shaft is achieved through a coupling.
在上述方案中,通过一种螺栓在下法兰上固定用于与减速箱壳体连接的冰钻支架,再通过另一种螺栓将冰钻支架固定在减速电机的减速箱壳体上,需要在下法兰、冰钻支架及减速箱壳体上设置多个用于配合螺栓的工艺孔,由于加工工艺较差以使工艺孔竖直度不好,且工艺孔数量较多,在完成螺旋式制冰机构与减速电机的装配后,存在冰钻与减速箱输出轴同轴偏差的问题,会导致冰钻的螺旋结构过度磨损,同时还会在冰钻使用时使减速箱输出轴承受过大的扭矩,会导致减速箱输出轴疲劳受损,会降低减速电机的使用寿命。In the above scheme, the ice auger bracket for connecting to the reduction gearbox housing is fixed on the lower flange by a bolt, and then the ice auger bracket is fixed to the reduction gearbox housing of the reduction motor by another bolt. It is necessary to set a plurality of process holes for matching the bolts on the lower flange, the ice auger bracket and the reduction gearbox housing. Due to the poor processing technology, the verticality of the process holes is not good, and the number of process holes is large. After the spiral ice-making mechanism and the reduction motor are assembled, there is a problem of coaxial deviation between the ice auger and the reduction gearbox output shaft, which will cause excessive wear of the spiral structure of the ice auger. At the same time, when the ice auger is in use, the reduction gearbox output shaft will be subjected to excessive torque, which will cause fatigue damage to the reduction gearbox output shaft and reduce the service life of the reduction motor.

其中,至少三个Y形定位块构成环形定位面,并不是指的是相邻两弧形定位面连接在一起,而是指至少三个弧形定位面所构成弧形开口的弧面的圆心同心,至少三个弧形定位面所在面处于同一个圆的圆周上。其中,延伸部至少三个,可以每个延伸部上都设置一个工艺孔,通过设置至少三个工艺孔,以保证装配紧固。其中,通过使负载壳体下端的配合面与Y形定位块的弧形定位面接触,还能实现减速箱壳体与负载壳体间的预定位,便于后续通过紧固件实现减速箱壳体与负载壳体间的固定。Among them, at least three Y-shaped positioning blocks constitute an annular positioning surface, which does not mean that two adjacent arc-shaped positioning surfaces are connected together, but means that the centers of the arc surfaces of the arc-shaped openings formed by at least three arc-shaped positioning surfaces are concentric, and the surfaces where at least three arc-shaped positioning surfaces are located are on the circumference of the same circle. Among them, there are at least three extensions, and a process hole can be set on each extension. By setting at least three process holes, assembly and tightening can be ensured. Among them, by making the mating surface at the lower end of the load shell contact with the arc-shaped positioning surface of the Y-shaped positioning block, the pre-positioning between the reducer shell and the load shell can also be achieved, which is convenient for the subsequent fixation between the reducer shell and the load shell by fasteners.
本发明通过提高减速箱壳体与负载壳体的同轴度,以提高减速箱输出轴与负载壳体处主轴的同轴度,从而保证装配后的主轴和减速箱输出轴转动顺畅,以避免使用时过度磨损,以延长使用寿命并降低噪音。The present invention improves the coaxiality of the reduction box housing and the load housing to improve the coaxiality of the reduction box output shaft and the main shaft at the load housing, thereby ensuring smooth rotation of the main shaft and the reduction box output shaft after assembly, avoiding excessive wear during use, extending the service life and reducing noise.
作为优选,所述减速箱壳体上端面中部具有上凸的环部,所述通孔位于环部中心处,所述负载壳体与减速箱壳体固定以使负载壳体下端位于环部与Y形定位块之间。Preferably, the middle of the upper end surface of the reduction gearbox housing has a convex ring portion, the through hole is located at the center of the ring portion, and the load housing is fixed to the reduction gearbox housing so that the lower end of the load housing is located between the ring portion and the Y-shaped positioning block.
上凸的环部以便于减速箱输出轴处轴承、密封圈等零部件的设置,以在保证零部件设置的情况下缩小减速电机整体体积。同时环部上凸,以使对负载壳体进行限位,可以通过使负载壳体内壁与环部周向外壁接触的方式对负载壳体进行定位,从而进一步保证负载壳体与减速箱壳体间的同轴度。同时,在负载壳体处漏水时,水只会堆积在环部与Y形定位块之间,绝大多数的水都会顺着相邻两Y形定位块间的开口向外侧流动,以避免负载壳体处泄漏的水堆积在减速箱壳体通孔处。The raised ring portion facilitates the arrangement of bearings, sealing rings and other components at the output shaft of the reduction gearbox, so as to reduce the overall volume of the reduction motor while ensuring the arrangement of the components. At the same time, the ring portion is raised to limit the load housing, and the load housing can be positioned by making the inner wall of the load housing contact with the circumferential outer wall of the ring portion, thereby further ensuring the coaxiality between the load housing and the reduction gearbox housing. At the same time, when water leaks at the load housing, water will only accumulate between the ring portion and the Y-shaped positioning block, and most of the water will flow outward along the opening between the two adjacent Y-shaped positioning blocks to avoid water leaking from the load housing accumulating at the through hole of the reduction gearbox housing.
作为优选,所述负载壳体偏离下端处设有向周向内侧延伸的配合部,所述主轴与配合部转动固定,且配合部中心处设有供主轴下端穿过的贯穿孔,当减速箱壳体与负载壳体固定以使主轴与输出轴同轴联动时,所述配合部位于所述减速箱壳体上方,且配合部下端面不与减速箱壳体接触。Preferably, a mating portion extending circumferentially inward is provided at a position deviating from the lower end of the load housing, the main shaft is rotatably fixed to the mating portion, and a through hole for the lower end of the main shaft to pass through is provided at the center of the mating portion, and when the reduction gear housing and the load housing are fixed so that the main shaft and the output shaft are coaxially linked, the mating portion is located above the reduction gear housing, and the lower end surface of the mating portion does not contact the reduction gear housing.
减少减速箱壳体与负载壳体的端面接触面积,以避免因端面加工问题导致负载壳体倾斜的情况发生,从而保证负载壳体内的主轴与减速箱壳体上的减速箱输出轴的同轴度。同时,配合部高于负载壳体下端的位置,当负载壳体内存在漏水现象时,泄漏的水会顺着负载壳体内壁流动至负载壳体下端处,然后水会移动至减速箱壳体与负载壳体的连接处,然后顺着Y形定位块向下流动,然后通过相邻两Y形定位块间的开口向外侧流动,以避免负载壳体处泄漏的水堆积在减速箱壳体通孔处。The end face contact area between the reduction box housing and the load housing is reduced to avoid the load housing tilting due to end face processing problems, thereby ensuring the coaxiality of the main shaft in the load housing and the reduction box output shaft on the reduction box housing. At the same time, the mating portion is higher than the lower end of the load housing. When there is water leakage in the load housing, the leaked water will flow along the inner wall of the load housing to the lower end of the load housing, and then the water will move to the connection between the reduction box housing and the load housing, and then flow downward along the Y-shaped positioning block, and then flow outward through the opening between the two adjacent Y-shaped positioning blocks, so as to avoid the water leaking from the load housing accumulating at the through hole of the reduction box housing.
作为优选,所述固定部数量与Y形定位块的数量相同,所述第一壳体上设有至少三个以通孔轴线为中心环形均匀间隔设置的Y形定位块,至少三个固定部呈环形均匀间隔设置在负载壳体外表面。Preferably, the number of the fixing parts is the same as the number of the Y-shaped positioning blocks, the first shell is provided with at least three Y-shaped positioning blocks evenly spaced in a ring shape with the through hole axis as the center, and at least three fixing parts are evenly spaced in a ring shape on the outer surface of the load shell.
固定部与Y形定位块一一对应,便于装配时的初步对准,以便于固定部与Y形定位块上工艺孔的对准。The fixing part corresponds to the Y-shaped positioning block one by one, which is convenient for preliminary alignment during assembly, so as to facilitate alignment of the fixing part with the process hole on the Y-shaped positioning block.
作为优选,所述弧形定位面沿通孔轴向的长度大于用于与弧形定位面接触的配合面沿通孔轴向的长度;当固定部支撑在延伸部上时,所述弧形定位面下端位于所述负载壳体下端面的下方;所述固定部下端面临近配合面处向上凹,或所述Y形定位块临近弧形定位面处向下凹;当固定部支撑在延伸部上时,所述固定部内端与Y形定位块内端间构成有避让槽。Preferably, the length of the arcuate positioning surface along the axial direction of the through hole is greater than the length of the matching surface for contacting the arcuate positioning surface along the axial direction of the through hole; when the fixing portion is supported on the extension portion, the lower end of the arcuate positioning surface is located below the lower end surface of the load housing; the lower end surface of the fixing portion is concave upward near the matching surface, or the Y-shaped positioning block is concave downward near the arcuate positioning surface; when the fixing portion is supported on the extension portion, an avoidance groove is formed between the inner end of the fixing portion and the inner end of the Y-shaped positioning block.
即当负载壳体与减速箱壳体配合时,负载壳体周向外壁只与打磨加工后的弧形定位面接触,不会与位于弧形定位面下侧的任何面接触,从而避免未加工的面对负载壳体造成影响。对减速箱壳体进行加工时,可以只对Y形定位块的弧形定位面进行加工,而不需要对其它不与负载壳体接触的侧面进行加工,以减少加工面积。That is, when the load housing is matched with the reduction box housing, the circumferential outer wall of the load housing only contacts the polished arc-shaped positioning surface, and does not contact any surface located below the arc-shaped positioning surface, thereby avoiding the unprocessed surface from affecting the load housing. When processing the reduction box housing, only the arc-shaped positioning surface of the Y-shaped positioning block can be processed, without processing other side surfaces that do not contact the load housing, so as to reduce the processing area.
同时负载壳体下端面只有固定部外端的下端面与Y形定位块外端的上端面接触,不会与减速箱壳体的其它处上端面处接触。对减速箱壳体进行加工时,可以只对Y形定位块的延伸部外端上端面进行加工,而不需要对其它不与负载壳体接触的端面进行加工,以减少加工面积。At the same time, only the lower end surface of the fixed part of the load housing contacts the upper end surface of the Y-shaped positioning block, and does not contact other upper end surfaces of the reduction box housing. When processing the reduction box housing, only the upper end surface of the extension part of the Y-shaped positioning block can be processed, and there is no need to process other end surfaces that do not contact the load housing, so as to reduce the processing area.
作为优选,所述减速箱壳体上端面为平面,所述减速箱壳体上端面设有向上延伸并包围所述Y形定位块的围合形的挡边,所述负载壳体下端周向外缘相对位于所述挡边周向内侧,所述挡边上设有缺口。Preferably, the upper end surface of the reduction gearbox housing is a plane, and is provided with an enclosing rib extending upward and surrounding the Y-shaped positioning block. The circumferential outer edge of the lower end of the load housing is relatively located on the circumferential inner side of the rib, and the rib is provided with a notch.
当负载壳体内存在密封不严的情况时,泄漏的水可以沿缺口流出,以避免水积在减速箱输出轴处,以避免减速电机进水。When there is a loose seal in the load housing, the leaked water can flow out along the gap to prevent water from accumulating at the output shaft of the reduction box and to prevent water from entering the reduction motor.
作为优选,所述Y形定位块偏离弧形定位面的侧壁构成有导向弧面,有一个Y形定位块的延伸段向所述缺口侧延伸。Preferably, the side wall of the Y-shaped positioning block deviating from the arc-shaped positioning surface is formed with a guiding arc surface, and an extension section of the Y-shaped positioning block extends toward the notch side.
通过在Y形定位块侧部形成导向弧面,以便于泄漏的水顺着导向弧面移动至缺口处,以便于积水的排出。A guide arc surface is formed on the side of the Y-shaped positioning block so that leaked water can move to the notch along the guide arc surface to facilitate the discharge of accumulated water.
作为优选,所述主轴下端设有向下开口的联动槽,所述减速电机减速箱输出轴上端截面外缘形状与联动槽截面内缘形状相同,且均为非圆形。Preferably, a linkage groove opening downward is provided at the lower end of the main shaft, and the outer edge shape of the upper end cross-section of the output shaft of the reduction motor reducer is the same as the inner edge shape of the cross-section of the linkage groove, and both are non-circular.
通过上述设置以能实现主轴与减速箱输出轴的直接联动,不需要采用联动器等进行扭矩传递,并进一步提高同轴度,从而能使制冰机高度方向上的空间做的更小,体积更小。The above arrangement can realize direct linkage between the main shaft and the output shaft of the reduction box, without the need for a coupling device etc. for torque transmission, and further improve the coaxiality, so that the space in the height direction of the ice maker can be made smaller and the volume smaller.
