Description

Technical Field

[0001] This utility model pertains to tools, specifically an auxiliary tool for disassembling and assembling slotted round nuts. Background Technology

[0002] Slotted round nuts are axial fasteners used in bearings, couplings, bushings, and other components of various equipment. They are commonly used to connect various fasteners, such as bearing brackets, motor bases, and vibrating machinery. Slotted round nuts are widely used in large machinery, construction and engineering projects, automobiles, trains, ships, and other transportation equipment, as well as electrical appliances, instruments, and meters. During the maintenance and repair of such equipment, it is often necessary to disassemble, install, or replace round nuts, which requires the use of specialized tools. Often, a hammer and chisel are used to impact the grooved edge, forcing rotation to complete the disassembly or assembly. However, this method can cause significant damage to the round nut, and the torque is difficult to control, easily damaging the threaded rod or sleeve, resulting in component damage.

[0003] Traditionally, crescent wrenches are used as specialized tools for installing or removing slotted round nuts. However, because the slots in slotted round nuts are shallow, crescent wrenches tend to slip when used for loosening or tightening, failing to meet the requirements for higher torque. Furthermore, crescent wrenches can only be used for externally slotted round nuts, not internally slotted round nuts, limiting their effectiveness due to the nut's position. Additionally, the wide variety of slotted round nut sizes, coupled with the inability of crescent wrenches to be adjusted to accommodate different sizes, necessitates the use of multiple crescent wrenches, which are difficult to carry and store, and inconvenient to operate. Summary of the Invention

[0004] To address the problems existing in current slotted round nut disassembly and assembly tools, this utility model proposes a tool suitable for various applications.

[0005] This combination wrench for disassembling and assembling slotted round nuts provides a simple, portable, and convenient tool for disassembling and assembling various sizes of slotted round nuts.
