交叉滾子軸承
在交叉滾子軸承中,因圓柱滾子在呈 90 ° 的 V 形溝槽滾動面上通過間隔保持器被相互垂直地排列,所以 1 個交叉滾子軸承就可承受徑向負荷、軸向負荷及力矩負荷等所有方向的負荷。內外圈的尺寸被最小限度地小型化,特別極薄型式是接近于極限的小型尺寸,并且具有高剛性,所以最適合于工業用機器人的關節部或旋轉部、機械加工中心的旋轉工作臺、機械手旋轉部、精密旋轉工作臺、醫療機器、計量器、 IC 制造裝置等的用途。
1、具有出色的旋轉精度
交叉滾子軸承內部結構采用滾子呈90°相互垂直交叉排列,
滾子之間裝有間隔保持器或者隔離塊,可以防止滾子的傾斜貨滾子之間相互磨察,有效防止了旋轉扭矩的增加。另外,不會發生滾子的一方接觸現象或者鎖死現象;同時因為內外環是分割的結構,間隙可以調整,即使被世家預壓,也能獲得高精度的旋轉運動。
2、操作安裝簡化
被分割成2部分的外環或者內環,在裝入滾子和保持器后,被固定在一起,所以安裝時操作非常簡單。
3、承受較大的軸向和徑向負荷
因為滾子在呈90°的V型溝槽滾動面上通過間隔保持器被相互垂直排列,這種設計使交叉滾子軸承就可以承受較大的徑向負荷、軸向負荷及力矩負荷等所有方向的負荷。
4、大幅節省安裝空間
交叉滾子軸承的內外環尺寸被最小限度的小型化,特別是超薄結構是接近極限的小型尺寸,并且具有高剛性,所以最適合于工業機器人的關節部位或者旋轉部位、機械加工中心的旋轉工作臺、機械手旋轉部、精密旋轉工作臺、醫療儀器、計量器具、IC制造裝置等廣泛用途。
5.轉速能力高
6.減少軸長度和加工成本,熱膨脹導致幾何尺寸的變化有限
7.采用尼龍分隔器,轉動慣量低,啟動扭矩低,易于控制角分度
8.優化預緊力,剛度大,引導滾子運轉精度高
9.滲碳鋼提供優良的抗沖擊力和表面抗磨能力
10.簡單但潤滑充分
RB型(外環分割型、內環旋轉用)
RB型交叉滾子軸承 |
Model RB (Separable Outer Ring, Type for Inner Ring Rotation)Being the basic
model of the Cross-Roller Ring, despite the minimum possible dimensions of the inner and outer rings, its outer ring is separable while the inner ring is integrated
with the main body. This model is used in locations where the rotation accuracy of the
inner ring is required.
RE型(內環分割型、外環旋轉用)
RE型交叉滾子軸承 |
此系列型號是由RB型的設計理念產生的新型式,主要尺寸與RB型相同。其構造是內環是分割型,外環是一體設計,適合于要求外環旋轉精度高的部位。
Model RE (Separable Inner Ring, Type for Outer Ring Rotation)
This new model is based on the design of principal of the RB, Having
the same major dimensions as model RB, its inner ring is separable
while the outer ring is integrated with the main body, this model is used
in locationswhere the rotation accuracy of the outer ring is required.
RU型、XSU型(內、外環一體型)
RU型交叉滾子軸承 |
此系列型號由于已進行了安裝孔的加工,就不需要固定法蘭和支撐座。另外,由于采用帶座的的一體化內外環結構,安裝對性能幾乎沒有影響,因此能夠獲得穩定的旋轉精度和扭矩。通過錐銷孔安裝滾子,能用于外環和內環旋轉。
Model RU 、Model XRU (Integrated Inner/Outer Ring Type)
Since the mounting holes are provided, this model does not require a presser flange or
housing. In addition, because it has an integrated inner/outer ring structure and is
equipped with washers, its performance is minimally affected by the mounting procedure,
ensuring stable rotation accuracy and torque. This model can be used for both inner-ring rotation and outer-ring rotation.
SX型(外環分割型,內環旋轉用)
SX型交叉滾子軸承 |
其結構與RB系列類似,外環是兩分割的結構,通過三個固定環連接,內環一體設計,適合于要求內環旋轉精度高的部位。
Model SX (Separable Outer Ring, Type for Inner Ring Rotation)
Its structure is similar to RB series, the outer ring is separable
and connected with three stating rings.While the inner ring is integrated
with the main body. This model is used in locations where the rotation
accuracy of the outer ring is required.
CRB型
CRB型(外環分割型、內環旋轉用)
CRB型交叉滾子軸承 |
Model CRB (Separable Outer Ring, Type for Inner Ring Rotation)
Its structure is that the outer ring is separable while the inner ring
is integrated with the main body. without cage ,but full complement。this model is used in locations where the rotation accuracy of the outer ring is required.
CRBC型(外環分割型、內環旋轉用)
其構造是外環是分割型,內環是一體設計,帶保持架滿裝滾子軸承。適合于要求內環旋轉精度高的部位。
Model CRBC (Separable Outer Ring, Type for Inner Ring Rotation)
Its structure is that the outer ring is separable while the inner ring is integrated with
the main body. with cage and full complement。this model is used in locations where the rotation accuracy of the outer ring is required.
CRBH型(內、外環一體型)
CRBH型交叉滾子軸承 |
該系列型號內、外環都是一體結構,通過錐銷孔安裝滾子,用于外環和內環旋轉。
Model CRBH (Integrated Inner/Outer Ring Type)
This model is with an integrated Inner/Outer Ring structure,can be used for both inner-ring rotation and outer-ring rotation.
RA型(外環分割型、內環旋轉用)
RA型交叉滾子軸承 |
此系列型號是將RB型內、外環厚度減小到極限的緊湊型。
適合于需要重量輕、緊湊設計的部位,例如機器人和機械手旋轉部位。
