Features:
- Lovejoy L190 coupling features three components; two units of L190 jaw coupling hubs and a spider of the same series.
- Lovejoy 68514412277 open-centre spider is designed for torque transmission between two shafts in motion control or vibration management applications.
- This spider permits both the driver and driven shafts to be placed within a short distance.
- This Lovejoy jaw coupling spider is made of bronze for ensuring excellent abrasion resistance and protection against dirt, oil, sand, grease & moisture.
Frequently Asked Questions:
Q. Why is a spider used in a coupling?
A. The spider determines the torque rating of a coupling. It also affects the coupling's response to temperature, vibration, misalignment, chemicals and high speed.
Q. What is a spider in a coupling?
A. Lovejoy jaw couplings are composed of three parts, i.e. an elastomer insert known as a spider and two metallic hubs on both sides. These three separate parts are pressed together with the help of a jaw from each hub, both of which are fitted alternately with the lobes of the spider to form a Lovejoy spider coupling.
Q. What is the colour significance of Lovejoy spiders?
A.
- Black - 80 Shore A hardness rating for excellent damping properties.
- Yellow - 92 Shore A hardness rating ideal for hydraulic applications.
- Red - 95 / 98 Shore A hardness rating suitable for high torque applications.
- Green - 64 Shore D hardness rating for humid environments.
- Blue - 92 & 95 Shore A hardness ratings for chemical resistance and high torque capabilities.
- Tan / Bronze - 55 Shore D hardness rating for chemical resistance.
Q. What is the difference between open center & solid center Lovejoy spiders?
A. The open center design is suitable for close BE situations (distance between the ends of driven and driving shafts), where the units must be positioned as closely as possible. However, this design has no full-diameter support, as the spider's legs are joined only by a thin segment of material. It has speed limitations up to 1750 rpm for NBR and 3600 rpm for Urethane / Hytrel. The solid center design, on the other hand, is suitable for general power transmission applications where the BE dimension will remain fairly constant and is capable of affording a suitable gap.
