1) Structural features: It is suitable for transmission occasions where the angle of the axis of the two shafts on the same plane of the connection space is less than or equal to 45°, and the nominal torque is 11.2~1120N·m.
2) The maximum included angle between each section is 45°.
3) The finished hole tolerance is H7, and the keyway, hexagonal hole and square hole can be opened according to the requirements.
4) Allow the angle between the two shafts to vary within a limited range as the work needs.
Mark description:
1) Coupling model: WXD-single cross type; WX-double cross type;
2) Shaft hole form:
φ-light cylindrical hole with taper pin hole; Y-cylindrical hole with key, with tightening nail.Shaft hole and key type and size comply with GB/T3852-2008 regulations.
S-square hole with tight nail; F-hexagonal hole with tight nail.
Installation and selection:
1) To ensure that the constant angular velocity of the rotary motion and the synchronous rotation between the main and driven shafts are maintained, a double cross shaft universal coupling or two single cross shaft universal couplings should be combined together, and meet the following requirements Three conditions:
① The angle between the intermediate shaft and the main and driven shafts is equal.
② Both ends of the intermediate shaft are in the same level with the three axes of the main and driven shafts.
③ The three axes of the intermediate shaft and the main and driven shafts are in the same plane.
2) Installation formCross shaft universal couplingWhen the angular velocity of the main and driven ends are not equal, the synchronous rotation between the main and driven shafts cannot be maintained, and the asynchrony changes with the included angle β.
