Optimal Solution for Mining Belt Conveyor Systems
Leave a CommentClimax Keyless Locking Devices provide advantages over keyed connections. Mining OEMs incorporate keyless connections in equipment design. Drum pulleys, especially head or tail pulleys, using traditional keyed connections introduce several compromises. Whenever a shaft is keyed, it must be oversized to account for the loss of effective cross section. This adds weight and cost not […]
Mining Shovels & Excavators Benefit From the Use of Climax KLDs
Leave a CommentClimax Keyless Locking Devices offer an alternative for clumsy clevis pin retention and brake rotors in excavators and dragline shovels. One of the most commonly used pieces of heavy mining equipment is excavators or power shovels. Every major construction project requires their use. Tasks such as removing large objects, digging trenches, site grading, hauling, demolition, […]
Mechanical Integrity Without Machining: KLD Solutions for Crusher Shaft Interfaces
Leave a CommentMining-grade crushing equipment can achieve greater mechanical integrity and simplified maintenance using Climax Keyless Locking Devices, which outperform conventional keyed connections. Jaw crushers widely used in the mining industry, often rely on costly press or sweat fits, or traditional keyed connections. However, these approaches often come with several drawbacks. Keyed shafts must be oversized to […]
What materials are used in the manufacturing of Climax shaft collars?
2 CommentsSteel Collars are the most commonly used and manufactured. The exact type of steel used varies depending on the machine process but generally low-carbon steel is used, including materials such as 1215, 1045, and 1026. Stainless Steel Collars are used primarily in applications
What finish does Climax offer on shaft collars?
2 CommentsBlack oxide finish on our mild steel collars is formulated as part of the total performance of the collar. The black oxide affects the anti-stick-slip characteristics and helps keep the torque rating of the screw within its design parameters. Black oxide also has corrosion
What is the industry standard for a shaft collar?
Leave a CommentWhile there is no formal industry standard for shaft collars, the dimensions of most manufacturers’ collars are fairly uniform. In most applications, the shaft collar bore (ID) is considered a critical dimension while other dimensions such as outer dimension and width are considered non-critical. Dimensions for Climax shaft collars can be found on our website […]
Why does a one-piece collar have a relief cut?
Leave a CommentThe relief cut removes some of the rigidity of a one-piece clamping collar to allow the screws to clamp more evenly and securely. A relief cut is important only on smaller bore collars because of the ratio of the screw to the collar material – the screw provides much of the clamp load. Climax puts […]
Why do clamping collars have face grooves?
Leave a CommentThe face groove on clamping collars indicates the face that should be placed against a bearing or other component requiring a perpendicular to bore orientation. For two-piece clamping collars, the face groove also helps keep the two halves of the collar properly oriented during installation.
Can a Climax shaft collar be welded?
Leave a CommentShaft collars can be welded with some exceptions. Mild steel and stainless steel materials contain sulfur and other additives which allow for welding. However, the lowest possible current and adequate ventilation should be employed. Be sure to remove screws before welding. However, in no cases should collars with zinc plating be welded. The welding process […]
What is axial holding power?
2 CommentsThe primary purpose of a shaft collar is to resist an axial load. That is to hold itself in place despite pressure along the axis of a shaft. The axial holding power is primarily a function of screw size and applied torque. However, other factors such as presence of oil, temperature, and the finish and […]
