The machine tool spindle refers to the axis on the machine that drives the workpiece or the tool to rotate.The main shaft components are usually composed of a main shaft, a bearing and a transmission member (gear or pulley). In the machine, gears and pulleys are mainly used to support transmission parts, machine tool spindles are used to support transfer motion and torque, some are used to clamp workpieces, such as mandrels.Most machine tools have spindle components, except for planers, broaching machines, etc., where the main motion is linear.The motion accuracy and structural rigidity of the spindle components are important factors in determining the machining quality and cutting efficiency.The indicators that measure the performance of the spindle components are mainly the accuracy of rotation, stiffness and speed.

Rotation accuracy：The radial and axial runout (see geometrical tolerance) that occurs in the direction of the machining accuracy is mainly determined by the manufacturing and assembly quality of the spindle and bearing.

Dynamic and static stiffness are mainly determined by the bending stiffness of the main shaft, the stiffness and damping of the bearing.

Speed adaptability:the maximum allowable speed and speed range is determined by the structure and lubrication of the bearing, as well as the heat dissipation conditions.

Industrial robot bearings mainly include thin-walled bearings, crossed cylindrical roller bearings, harmonic reducer bearings and joint bearings, but mainly cross-roller bearings.Cross-roller bearing structure in welding robot joints: Cylindrical rollers are vertically arranged in the inner and outer raceways of the bearing, and a single bearing can simultaneously bear the common load of radial force, bidirectional axial force and overturning moment.The bearing has large bearing capacity, good rigidity, high rotation precision, easy installation, space saving, weight reduction, significant friction reduction, and good rotation precision.

A turbocharger is actually an air compressor that uses compressed air to increase the amount of intake air.It uses the inertial force of the exhaust gas from the engine to push the turbine in the turbine chamber. The turbine drives the coaxial impeller. The impeller presses the air sent by the air filter pipe to pressurize it into the cylinder.When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase, the impeller compresses more air into the cylinder, and the increase in air pressure and density can burn more fuel, correspondingly increase the fuel amount and adjust the engine speed. It can increase the output power of the engine.

The turbocharger has five main advantages:

Increase engine power.

By increasing the intake density while the engine displacement is constant, the engine can be injected more fuel, thereby increasing the power of the engine. In addition, the power and torque of the engine after adding the supercharger should be increased by 20%~30%. Conversely, under the same power output requirements, the cylinder bore of the engine can be reduced, and the size and weight of the engine can be reduced.

Improve engine emissions

The turbocharger engine reduces the displacement of harmful components such as particulate matter and nitrogen oxides in the engine exhaust by improving the combustion efficiency of the engine.This is an indispensable configuration for diesel engines to meet Euro II emission standards.

Provide the function of altitude compensation.

In some high-altitude areas, the higher the altitude, the thinner the air, the engine with a turbocharger can overcome the power drop of the engine caused by the thin air of the plateau.

Improve fuel economy and reduce fuel consumption.

Since the engine with turbocharger has better combustion performance, it can save 3%-5% of fuel.

High reliability and good matching characteristics, high transient response characteristics.

The growing demand for modern agriculture, scale, location, elevation, climate, soil structure and crop rotation, make each farm unique.Agricultural equipment needs to operate under many similar and challenging conditions.For example, mud, dust and debris are everywhere, the temperature is extremely hot and extremely cold, the rain is washed away, and sometimes corrosive chemicals.Sometimes agricultural equipment is idle for a long time, and then it must be operated intensively.In addition, rising fuel costs and new environmental regulations can only complicate matters.

Agricultural solutions can meet these needs and we understand the needs of modern farmers.We walked into their fields together to explore the challenges and concerns they face.We work closely with original equipment manufacturers to develop solutions to practical problems and then verify that the solution is feasible in our laboratories and work farms.

Agricultural Solutions develops a range of products and services to help original equipment manufacturers and farmers meet the growing needs of the changing industry.No matter what the product, from complex combinations to specialized accessory farming solutions benefit end users: reduced maintenance costs, longer equipment life, reduced fuel and grease usage, higher levels of automation and precision, higher equipment Work ability, safety and comfort.
