Description

一种洗衣机减速离合器及洗衣机 技术领域
本发明涉及洗衣设备，尤其是一种洗衣机减速离合器及洗衣机。
背景技术
现有的波轮洗衣机的减速离合器内部一般安装有两组轴承，分别为位于内筒一侧的前轴承和位于电机一侧的后轴承，两轴承共同用于支撑内筒轴。制动轮的前端装在内筒轴上，后端通过压铆工艺固定在封油盖上，这种压铆工艺使得制动轮和封油盖连接后可以抵抗较大的轴向载荷，但抵抗径向载荷的能力较小。在洗衣机运转中，由于内筒的晃动，会对制动轮和制动轮的连接处施加较大的径向载荷，容易造成制动轮和封油盖铆接处松动，进一步使得内筒晃动扩大，最终内筒与外筒摩擦，出现噪音大和振动大的问题。
鉴于此提出本发明。
实用新型内容
本发明的目的在于克服现有技术的不足，提供一种使用寿命长，能够降低内筒径向晃动的洗衣机减速离合器。
本发明的另一目的在于提供一种配置有上述洗衣机减速离合器的洗衣机。
为了实现第一目的，本发明采用如下技术方案：
一种洗衣机减速离合器，包括，轴承座、输入轴、输出轴、所述输入轴与输出轴同轴设置，套设在输入轴和输出轴上的输出轴套，所述输出轴套通过轴承安装在轴承座上，输出轴套与输入轴通过行星轮系传动连接，所述输出轴套的两端和中部各设有至少一轴承，所述轴承的内圈与输出轴套配合，外圈与轴承座配合。
进一步，所述输出轴套包括，内筒轴、制动轮和封油盖，所述内筒轴和封油盖分别位于制动轮的两侧，并与制动轮固定连接；所述轴承包括，安装在内筒轴上的第一轴承，安装在制动轮上的第二轴承和安装在封油盖上的第三轴承。
进一步，所述第二轴承的内圈与制动轮外周壁为间隙配合，外圈与轴承座内壁为过 盈配合，通过这种设置方式，可以允许制动轮做微小的径向移动，在制动轮发热时，为制动轮留出一定的形变空间，并且也便于装配。
进一步，所述轴承座包括第一轴承座和第二轴承座，所述第一轴承座与第二轴承座固定连接，并形成容纳输出轴和输出轴套的型腔，所述第一轴承座和第二轴承座上分别设有用于定位轴承的定位结构。
进一步，所述第一轴承座和第二轴承座上设有相互配合的定位结构，以共同限定第二轴承的轴向移动。
进一步，所述第一轴承座上设有第一定位面和第二定位面，所述第二轴承座上设有第三定位面和第四定位面；第一定位面与第一轴承定位配合，所述第三定位面与第三轴承定位配合，第二定位面和第四定位面共同与第二轴承定位配合。
进一步，所述第二定位面与第二轴承外圈的一个端面接触配合，第四定位面与第二轴承外圈的另一个端面接触配合。
进一步，所述第二定位面为设置在第一轴承座的内腔壁上的阶梯面，所述第四定位面为第二轴承座的一个端面，具有该端面的第二轴承座的端部插入至第一轴承座的内腔中，使该端面位于第一轴承座的内腔中，并与所述第二定位面相对设置。
进一步，所述内筒轴为阶梯轴，并设有阶梯面与第一轴承定位配合；所述封油盖上卡装有一C型挡圈，所述C型挡圈位于第三轴承远离内筒轴的一侧，并与第三轴承定位配合。
为了实现第二目的，本发明采用如下技术方案：
一种配置有上述的洗衣机减速离合器的洗衣机。
采用本发明所述的技术方案后，带来以下有益效果：
本发明的洗衣机减速离合器在现有的前后轴承之间增加了一轴承，用于对输出轴套的中部进行支撑，提高了输出轴套抵抗径向载荷的能力，使得制动轮和封油盖连接处受力减小，避免了制动轮和封油盖连接处松动或断裂，并且降低了内筒运行时的晃动幅度，避免了内筒转动过程中与外筒碰撞，因此使用寿命更长，并降低了维护成本，本发明的洗衣机运行时噪音低，用户体验更好。

具体实施方式
下面结合附图对本发明的具体实施方式作进一步详细的描述。
实施例一
如图1和图2所示，一种洗衣机减速离合器，包括，轴承座1、输入轴100、输出轴3、输入轴100与输出轴3同轴设置，套设在输入轴100和输出轴3上的输出轴套2，所述输出轴套2与输入轴100可相对转动，且两者通过行星轮系传动连接。优选地，输入轴100与输出轴3为通轴，两者为一体结构。所述输入轴100与电机转轴连接，输出轴3与内筒中的波轮连接，所述输出轴套2与内筒连接，用于带动内筒转动。输出轴套2通过轴承安装在轴承座1上，可相对轴承座1转动，轴承座1用于支撑输出轴套2。所述输出轴套2的两端和中部各设有至少一轴承，形成三点支撑，使得输出轴套2的两端和中部均得到支撑，所述轴承的内圈与输出轴套2配合，外圈与轴承座配合。
具体地，所述输出轴套2包括，内筒轴21、制动轮22和封油盖23，所述内筒轴21和封油盖23分别位于制动轮22的两侧，并与制动轮22固定连接，三者同步运动。具体地，内筒轴21与制动轮22插接，两者过盈配合，封油盖23与制动轮22铆接。所述内筒轴21与内筒固定连接，行星轮系设置在制动轮22内，包括，固定安装在输入轴100上的太阳轮8，与太阳轮8啮合的行星轮7，所述行星轮7安装在行星轮架上，在制动轮22内壁上设有与行星轮7配合的齿，或者在制动轮22内固定设置有一外齿圈，外齿圈的内侧与行星轮7啮合，在太阳轮8转动时可通过行星轮7带动制动轮22转动。
所述轴承包括，安装在内筒轴21上的第一轴承4，安装在制动轮22上的第二轴承 5和安装在封油盖23上的第三轴承6。第一轴承4和第三轴承6的内圈分别与内筒轴21和封油盖23过盈配合，外圈与轴承座1过盈配合或间隙配合。由于制动轮22和封油盖23同时受轴承的支撑，因此，当制动轮22和封油盖23承受径向载荷时，所受压力被轴承吸收，避免了压力集中作用在两者的连接处，造成制动轮22和封油盖23的连接处开裂。
所述内筒轴21为阶梯轴，并设有阶梯面与第一轴承4定位配合；所述第二轴承5的内圈与制动轮22外周壁为间隙配合，外圈与轴承座1内壁为过盈配合，通过这种设置方式，可以允许制动轮22做微小的径向移动，在制动轮22发热时，为制动轮22留出一定的形变空间，并且也便于装配。
所述轴承座1包括第一轴承座11和第二轴承座12，第一轴承座11用于安装在外筒上，第一轴承座11与第二轴承座12固定连接，并形成容纳输出轴3和输出轴套2的型腔，所述制动轮22位于型腔的内部，所述第一轴承座11和第二轴承座12上分别设有用于定位轴承的定位结构。其中，第一轴承4和第三轴承6分别由第一轴承座11和第二轴承座12单独定位，第二轴承5由第一轴承座11和第二轴承座12上设有的相互配合的定位结构共同定位。
具体地，所述第一轴承座11上设有第一定位面111和第二定位面112，所述第二轴承座12上设有第三定位面121和第四定位面122；第一定位面111与第一轴承4定位配合，以限制第一轴承4向电机一侧运动；所述第三定位面121与第三轴承6定位配合，以限制第三轴承6向电机一侧运动。第二定位面112和第四定位面122共同与第二轴承5定位配合，所述第二定位面112与第二轴承5外圈的一个端面接触配合，用于限制第二轴承5向内筒一侧运动，第四定位面122与第二轴承5外圈的另一个端面接触配合，用于限制第二轴承5向电机一侧运动。
优选地，第一定位面111和第二定位面112为设置在第一轴承座11的内腔壁上的阶梯面，第三定位面121为设置在第二轴承座12上的阶梯面，所述第四定位面122为第二轴承座12的一个端面，具有该端面的第二轴承座12的端部插入至第一轴承座11的内腔中，使该端面位于第一轴承座11的内腔中，并与第二定位面112相对设置。
优选地，第二轴承5的端面与第四定位面122之间留有一微小的间隙，以允许第二轴承5作微量轴向移动。
所述内筒轴21与第一轴承座11之间还设有一大油封10，所述输出轴3与第二轴承 座12之间还设有密封端盖，第一轴承座11与第二轴承座12形成的型腔被密封，以避免灰尘进入至该型腔内。
实施例二
结合图3和图4所示，在实施例一中，输出轴套2未完全轴向限位，因此，可能使得输出轴套2向内筒一侧窜动，本实施例与实施例一的区别在于，第三定位面121设置在第三轴承6靠近制动轮22的一侧，并限制第三轴承6向内筒一侧运动，所述封油盖23上卡装有一C型挡圈9，所述C型挡圈9位于第三轴承6的另一侧，并与第三轴承6定位配合，以限制输出轴套2向内筒一侧运动。当输出轴套2向电机一侧运动时，将被第一轴承座11上的第一定位面111限制，当输出轴套2向内筒一侧运动时，将被第二轴承座12上的第三定位面121限制，使得输出轴套2被完全轴向限定，避免发生轴向窜动。
本领域技术人员还应理解，本发明实施例中所称的“左”、“右”等用于表示方位或位置关系的用语是以附图状态为基准而言的，这些用语仅是为了便于描述和理解本发明的技术方案，而不是指示或暗示所指的装置或不见必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
以上所述为本发明的实施方式，应当指出，对于本领域的普通技术人员而言，在不脱离本发明原理前提下，还可以做出多种变形和改进，这也应该视为本发明的保护范围。
