German Caspar Gleitlager coupling Caspar Gleitlager model Caspar Gleitlager price

Caspar Gleitlager couplings connect several sets of diaphragms (stainless steel thin plates) to the two half-couplings with bolts in a staggered arrangement. Each set of diaphragms consists of multiple stacked layers. The diaphragms are categorized into link-type and solid-piece types of various shapes. Diaphragm couplings compensate for the relative displacement of the two connected shafts through the elastic deformation of the diaphragms. They are high-performance, metallic, flexible couplings that require no lubrication, feature a compact structure, high strength, long service life, zero rotational backlash, and are unaffected by temperature or oil contamination. They offer acid, alkali, and corrosion resistance, making them suitable for shaft drive systems operating in high-temperature, high-speed, and corrosive media environments.

Caspar Gleitlager coupling introduction

They are divided into two main categories: convex and concave. The convex type is further divided into three variants: integral with skeleton, integral without skeleton, and radial slit. Their common feature is connecting the two half-couplings with bolts via a tire ring to achieve shaft connection. The inner side of the tire ring is bonded to a steel skeleton using vulcanization, with nuts welded at the bolt holes on the skeleton. During assembly, bolts connect to the flanges of the two half-couplings. Torque is transmitted through the friction generated between the tire and the flange end faces by tightening the bolts. The tire ring undergoes torsional shear deformation during operation, giving tire couplings high elasticity, significant capacity to compensate for relative shaft displacement, and good damping. They also feature a simple structure, require no lubrication, and are easy to assemble, disassemble, and maintain.

Caspar Gleitlager coupling imbalance phenomena

Due to various reasons, the center of mass or principal axis of inertia of a tire coupling may not coincide with its axis of rotation. This results in unbalanced centrifugal inertial forces, centrifugal inertial couples, and dynamic deflection (vibration modes) during operation, known as rotor imbalance. This imbalance inevitably causes vibration in the shaft system, affecting normal machine operation and service life, so it must be addressed. To correct or minimize the imbalance of tire couplings, an appropriate balance grade should be selected as needed. After manufacturing and installation on the machine, balance correction is performed on the specified balance (correction) plane of the coupling by adding or removing appropriate mass to meet the balance grade requirements. This process is called balance correction, or simply balancing. The degree of imbalance (imbalance amount U) is typically expressed by the product mr of the rotor mass m and the distance r from the center of mass to the rotor's axis of rotation, known as the mass-radius product. Alternatively, it can be expressed as the mass-radius product per unit mass, known as eccentricity e (not in the geometric sense). The mass-radius product mr is a relative quantity related to rotor mass, while eccentricity e is an absolute quantity independent of rotor mass. The former is more intuitive and commonly used for balancing specific rotors, while the latter is used to evaluate the quality of rotor balancing or detect balancing precision. The balance grade standard for tire couplings is assessed based on e.

Caspar Gleitlager coupling maintenance

1) For jaw couplings, listen for abnormal noises or manually rotate the two half-couplings to check for excessive circumferential play. If present, the jaw rubber ring may be damaged; alternatively, check for looseness between the half-coupling and the shaft. 2) For flange couplings, if the bolt holes or pin holes in the two half-couplings are severely worn, machining the holes and fitting suitable bolts is typically adopted, or electric welding can be used to fill the holes before re-machining. 3) For slider couplings, pay attention to lubrication conditions. 4) For gear couplings, inspect the tooth profile using calipers, span micrometers, or templates. If tooth thickness wear exceeds 5~30% of the original tooth thickness, replacement is required; for running mechanism gear couplings, the limit is 20~30%. 5) Check gear coupling sealing devices, retaining rings, expansion rings, springs, etc., for damage or aging, and replace them promptly if found. 6) If the fit between the half-coupling or gear coupling bushing and the shaft does not meet drawing requirements, or if there are significant scratches on the shaft due to key loosening, timely repair is necessary. Generally, only the coupling or bushing is repaired; shaft repair is not permitted to prevent shaft breakage accidents. 7) Lubricated couplings require regular oiling. Slider couplings, universal joints, chain couplings, etc., must be regularly lubricated. Our company uses universal joints extensively, especially in the packaging workshop.
