Description

说明书 发明名称：一种新型双排轴承传输轮
技术领域
[0001] 本实用新型涉及一种轮子， 具体涉及一种包覆有弹性体的传输轮， 传送轮或者 输送胶轮。
背景技术
[0002] 目前市面上的输送胶轮多为由金属芯,塑料芯粘接弹性体材料， 然后再装备轴 承。 用卡簧或者直接冲压方式锁死轴承。 在老式的加工过程中首先需要将金属 芯或者塑料芯进行表面粗糙处理， 然后再进行硫化包胶， 然后再对表面毛边处 理， 然后再装上轴承， 然后再装上卡簧或者将轴承外圈与金属或者塑料内圈的 凸起位冲压卡死；
[0003] 在老式的加工中存在的缺陷： 在弹性体硫化加工过程中由于金属芯 （未热处理 ) 和塑料芯在加温过程中受热容易变形， 强度不够。 使得弹性体材料可以在变 形位置流动， 使得产品外观不良， 需要进行 2次磨床加工。 在输送轮装备轴承和 锁死轴承的过程中由于冲床或者液压冲床多次加工使得增加产品成本降低合格 率。 并且由于老式输送轮的轴承和金属芯或者塑料芯装备在一起吋候， 需要考 虑配合装备尺寸， 使得轴承有型号和大小的局限性 （尤其在小于 80mm外径的输 送轮） ， 使用过小的轴承使其承受负荷过大， 使用寿命降低。
技术问题
[0004] 本实用新型所要解决的技术问题在于针对上述现有技术中的不足， 提供一种新 型双排轴承传输轮， 其安装简单， 寿命长， 生产效率高， 成本低。
问题的解决方案

[0006] 所述内圈的一边凸出， 形成凸出部； 一边凹进去， 形成凹陷部， 中心设有通孔 或者直接是螺牙， 锁紧螺丝将内圈锁死固定， 锁紧螺丝头沉入所述内圈的凹陷 部； 内圈与锁紧螺丝一起不旋转；
[0007] 所述外圈与弹性体硫化粘接； 轴承外圈旋转内圈不转动； 外圈外表面加工至少 一条凹槽；
[0008] 所述滚动体在内圈和外圈之间滚动； 包含双排滚动体， 并分布在轴承两端位置
[0009] 所述保持架把轴承中的两组钢球或滚子均匀地相互间隔幵来；
[0010] 所述防尘盖放置于轴承内圈与外圈之间紧扣；
[0011] 所述外端密封盖放置于内圈的凹陷部位置， 与轴承外圈紧配安装。
[0012] 进一步的是： 所述弹性体的外表面为圆形或有齿型或斜齿型。

[0015] 本实用新型在生产过程中只需把轴承和弹性体通过硫化粘接就可以了， 避免的 后续的加工， 可以提升生产效率降低成本， 轴承内圈外圈工艺热处理， 从而提 高接触疲劳强度和抗压强度和抗蚀能力， 因为在定制生产轴承过程中内圈凸起 使其后续安装一步到位， 减少零配件安装简单， 因为轴承直接接触弹性体， 使 其设计尺寸范围加大， 可以增大减少外圈内圈滚动体尺寸， 从而增加载重负荷 ， 双排的滚动体使得产品不易摆动， 晃动， 偏重， 减少跳动。 产品质量大幅提 升。 外端密封盖可盖住轴承部分， 使得整体外观更加漂亮；
[0016] 以往的传输轮由外圈和弹性体粘接然后在安装轴承， 锁紧轴承的做法由于生产 工艺复杂， 工序多。 废品率高。 单个轴承承载负荷小， 摆动大， 使得传输轮寿 命短。 而且在后续的使用中要另外添加间隔套， 使其轴承内圈接触间隔套将其 间隔， 轴承外圈旋转内圈不转动。 对附图的简要说明
