Brass Couplings Meet The Technical Requirements

Brass coupling with brass coupling drive machine, brass coupling two-axis alignment deviation and brass coupling end face clearance, should meet the machine's technical documentation requirements.

Brass coupling varieties, types, specifications a lot, in the correct understanding of the variety, type, specifications on the basis of their own, according to the needs of the transmission to choose brass coupling, first from the already developed as a standard brass coupling In the selection, I have developed for the international and the standard of brass coupling dozens of these standard brass coupling is the vast majority of general brass coupling, universal brass coupling, each Brass coupling has its own characteristics and suitable range, the basic to meet the needs of a variety of conditions, under normal circumstances, designers do not need to design their own brass coupling, only in the existing standard brass coupling can not Meet the needs of their own design brass coupling. Standard brass coupling easy to buy, the price than the design of non-standard brass coupling to be much cheaper. In many standard brass couplings, the right choice for their own needs the best brass coupling, related to the mechanical product shaft drive work performance, reliability, service life, vibration, noise, energy saving, transmission efficiency , Plastic Brass Push in Coupling Transmission accuracy, economy and a series of issues, but also related to the quality of mechanical products. Designers in the selection of brass coupling should be based on the angle from the shaft drive and the need to select the brass coupling, should be avoided only consider the main and driven side coupling selection brass coupling.

First, choose brass coupling should be considered factors

(A) mechanical characteristics of the power machine

Power machine to work machine, through one or several different varieties of type, Plastic Brass Push in Coupling the specifications of the brass coupling will be the main and driven end connected to form a shaft drive system. In the mechanical transmission, the power machine is nothing more than the motor, the internal combustion engine and the gas turbine. Due to the different working principle and mechanism of the power machine, the mechanical characteristics of the machine are quite different, and some of the operation is stable, and some have impact, and the influence of the transmission system is different. According to the mechanical characteristics of the power machine, the power machine is divided into four categories.

The mechanical characteristics of the power machine have a certain impact on the entire transmission system, different types of power machine, due to its different mechanical properties, should select the corresponding power coefficient Kw, select the best brass coupling for the system. The type of power machine is the basic factor in selecting the variety of brass coupling. The power of the power machine is one of the main basis for determining the size of the brass coupling, which is proportional to the torque of the brass coupling. Fixed mechanical products in the transmission system are mostly electric motors, running mechanical products transmission system (such as ships, Plastic Brass Push in Coupling all kinds of vehicles, etc.) in the power engine for the internal combustion engine, when the power machine for the cylinder number of different internal combustion engine, you must consider the torsional vibration Transmission system, the impact of this factor and the number of internal combustion engine, the cylinder is related to the normal work. At this time generally should use the elastic brass coupling to adjust the natural frequency of the shaft to reduce the torsional vibration amplitude, so as to damping, buffer, protect the transmission parts, improve the performance, improve the stability of the output power.

Due to the different structure and material, for each mechanical product transmission system brass coupling, the load capacity is very different. Plastic Brass Push in Coupling The load category is mainly for the working load of the machine impact, vibration, forward and reverse, braking, frequent start and other reasons to form different types of load. In order to facilitate the selection of the calculation, the transmission system load into four categories

The load type of the drive system is the basis for selecting the brass coupling. Shock, vibration and torque changes in the larger working load, should be selected with flexible components of the flexible brass coupling that is flexible brass coupling to buffer, vibration, compensation axis offset, Plastic Brass Push in Coupling improve the transmission system performance The Starting frequent, positive and negative, the torque is normal when the normal operation of the torque several times, is overloading work, will inevitably shorten the life of the brass coupling elastic components, brass coupling only allows short-term overload , The general short-term overload shall not exceed 2 to 3 times the nominal torque, that is, [Tmax] ≥ 2 ~ 3T n.

Low-speed operating conditions should be avoided only for small and medium-power brass coupling, for example: elastic sleeve pin brass coupling, core elastic brass coupling, Plastic Brass Push in Coupling polygonal rubber brass coupling, Brass coupling, etc .; need to control the safety of the shaft safety protection, should use the safety of brass coupling; load changes and the impact of large, vibration shaft, should choose to have elastic components and cushioning and damping effect Better elastic brass coupling. Metal elastic element elastic brass coupling bearing capacity higher than non-metallic elastic components elastic brass coupling; elastic components by extrusion elastic brass coupling reliability is higher than the elastic element by the elastic elastic brass Shaft.
