In the field of mechanics, there are many widely adopted mechanical structures, but for newcomers to this field, these classic mechanical structures may still be unfamiliar. This article aims to lead you to a deeper understanding of several popular mechanical devices. 1. Linear guide and linear motion assembly An example is a linear motion mechanism […]

1. Gear reducer Type: cylindrical gear reducer, bevel gear reducer, helical gear reducer, etc. Features: High transmission efficiency (90%-98%), suitable for high-power scenarios. Strong load-bearing capacity, suitable for heavy-duty industrial equipment (such as mining machinery, metallurgical equipment) with compact structure, but some types (such as spur gears) have high noise. Transmission ratio range: Single-stage transmission

1. Manual lubrication method This is the most traditional method and is suitable for situations where the lubricant is insufficient. The lubricant is replenished manually using a refueling device. However, this method is difficult to maintain a stable oil volume and there is a risk of forgetting to refuel, so it is mostly used in

1. “Obedient” control performance: function ≠ performance! What is the core task of hydraulic valves? It is not “being able to adjust pressure”, but “adjusting steadily and accurately”! For example: the same pressure regulating valve, some valves have very good data in the laboratory, but when installed on the equipment, the pressure fluctuation is as

The hydraulic support is the core equipment of the fully mechanized mining face. During the coal mining process, it can effectively support the weight of the roof rock to prevent the roof from collapsing and endangering the safety of personnel and damaging the equipment. It can also move flexibly as the coal mining progresses to

If insufficient pressure occurs during the operation of the hydraulic press, it may be caused by low efficiency or excessive leakage, damage or blockage of the relief valve, too little hydraulic oil, blockage of the oil inlet pipe or oil filter, severe wear or damage of the hydraulic pump, etc. During maintenance, the oil level,

Correct installation of hydraulic hoses is extremely important. Most hose failures are caused by improper installation of the hose assembly on the hydraulic system. 1. Hydraulic pipeline layout basics In the hydraulic system, the fixed layout is connected by steel pipes, and the layout between the movable parts is connected by hoses. If the cost

Hydraulic proportional valves and servo valves are more common in hydraulic systems. There is always an ambiguous feeling between the two. So, what are the similarities and differences between them? 1. Similarities (1) Basic functions ① Hydraulic control: Hydraulic proportional valves and servo valves are both hydraulic control components. Their core function is to control

1.Selection and installation of hydraulic gear pumps When selecting a hydraulic gear pump, it is necessary to make a judgment based on the properties of the liquid to be transported. At the same time, it is necessary to conduct a detailed inspection of the pump’s performance requirements and analyze its suction and discharge conditions, whether

The motor model is a code used to facilitate business contacts between users, designers, manufacturers and other departments and to simplify the description of product names, specifications, models, etc. in technical documents. The motor model consists of four parts: motor type code, motor specification code, special environment code and supplementary code. 1. Motor model composition
