车库门滚轮组件的改进优势有哪些?

来源:http://www.cishanfst.com 日期:2020-09-01 发布人:hongshun
通常用作车库门的上推式悬挂门包括多个铰接在一起的门组件。通常,这种悬挂门支撑在一对L形的轨道上,这样,轨道就可以使车库门从大致垂直关闭状态向上移动到水平开启状态。为了使之能完成这样的移动,在靠近车库门的侧边上安装有多个滚轮支撑件。每个滚轮支撑件上都有一个滚轮,这个滚轮咬合在一固定的L形轨道上并可在上面滚动。通常,滚轮支撑件还包括一对将相邻的门段铰接在一起的对置的对接铰片。对接铰片上有一个用于插接滚轮的芯轴的金属铰接管。
A push-up suspension door commonly used as a garage door consists of a plurality of hinged door assemblies. Usually, the suspended doors are supported on a pair of L-shaped tracks, which allow the garage door to move up from roughly vertically closed to horizontally open. In order to complete such movement, a plurality of roller supports are installed on the side edge close to the garage door. There is a roller on each roller support, which is engaged on a fixed L-shaped track and can roll on it. Generally, the roller support also includes a pair of opposite butting hinge pieces that hinge the adjacent door segments together. There is a metal hinge connecting pipe for inserting the mandrel of the roller on the butt hinge.
通常的滚轮支撑件上的滚轮大都是由金属件构成,这样,当门移动的时候,由于滚轮和L形轨道间是金属与金属的接触,将产生很大的噪音。而且,为了降低材料成本,通常这样的滚轮支撑件采用的是普通钢。虽然滚轮支撑件通常安装在悬挂门内侧,但仍然还有许多构件是暴露在外的,因而生锈和其它一些腐蚀问题也不可避免。这样的腐蚀将会使门所产生的噪音更大,而且会使滚轮支撑件损坏。
Generally, the roller on the roller support part is mainly composed of metal parts. In this way, when the door moves, the metal to metal contact between the roller and the L-shaped track will produce a lot of noise. Moreover, in order to reduce the material cost, the roller support is usually made of ordinary steel. Although the roller support is usually installed inside the suspension door, there are still many components exposed, so rust and other corrosion problems are inevitable. Such corrosion will make the door produce more noise and damage the roller support.

针对上述问题,我公司对滚轮支撑件做了改进,在通常的滚轮支撑件的金属芯轴上可旋转地安装上塑料滚轮。这种滚轮支撑件所产生的噪音比带有金属滚轮的滚轮支撑件所产生的噪音要小。另外,塑料滚轮还不会腐蚀。但是,这样的滚轮支撑件要比全钢制成的滚轮支撑件昂贵,在成本上不具竞争力。
In view of the above problems, our company has improved the roller support, and the plastic roller can be installed on the metal mandrel of the roller support part. The noise generated by the roller support is smaller than that generated by the roller support with metal roller. In addition, the plastic roller will not corrode. However, this kind of roller support is more expensive than the roller support made of all steel, so it is not competitive in cost.
改进优势是车库门上的滚轮组件,该滚轮组件包括一个芯轴和一个由聚合材料制成的滚轮。芯轴包括一个轴杆部分和一个座圈部分。其中轴杆部分安装在车库门上,并使座圈部分伸出门侧边之外一段距离。一个从滚轮内表面沿径向向内凸出的凸肩部分,它被安装在座圈部分的一个环行凹槽内。滚轮的外端部咬合在位于通道侧边的L形轨道上。
The improvement advantage is the roller assembly on the garage door, which includes a mandrel and a roller made of polymer material. The mandrel includes a shaft rod part and a seat ring part. The shaft rod part is installed on the garage door, and the seat ring part extends a distance beyond the side of the door. A shoulder part protruding radially from the inner surface of the roller is installed in a circular groove of the seat ring part. The outer end of the roller is engaged on the L-shaped track at the side of the channel.
芯轴和滚轮都是单个整体构件,芯轴是由玻璃纤维加强的尼龙制成的,滚轮则由具有高冲击性能的尼龙制成。座圈部分上有一个轮毂远端部分和一个远端坡面,一个凹槽将它们与一个轮毂近端部分及一个近端坡面相隔开。远端和近端坡面分别从远端和近端轮毂外表面向凹槽外表面方向延伸。滚轮包括远端和近端坡面,它们分别与座圈部分的远端和近端坡面相对。
Both the mandrel and the roller are single integral components. The mandrel is made of glass fiber reinforced nylon, while the roller is made of nylon with high impact performance. On the seat ring part, there is a distal part of the hub and a distal slope surface, and a groove separates them from a proximal part of the hub and a proximal slope surface. The far end and near end slope extend from the outer surface of the far end and the near end hub to the outer surface of the groove respectively. The roller comprises a far end slope surface and a proximal slope surface, which are opposite to the far end slope surface and the proximal slope surface of the seat ring part respectively.
