- In conclusion, the spark plug motor represents an exciting leap forward for the automotive industry, blending traditional combustion engine technology with modern electrical engineering to create a potential game changer. Its impact could be felt across various sectors, from consumer vehicles to commercial transport and beyond. As research continues and the technology matures, one thing is clear the spark plug motor is set to ignite a small but significant revolution in how we power our vehicles, ushering in a new era of efficiency and eco-friendliness on the roads.
The skeleton oil seal structure consists of three parts: the oil seal body, the reinforced skeleton and the self-tightening coil spring. The sealing body is divided into bottom, waist frame oil seal structure diagram, cutting edge and sealing lip according to different parts. Generally, the inner diameter of the skeleton oil seal in the free state is smaller than the shaft diameter, that is, it has a certain interference. Therefore, after the oil seal is installed on the oil seal seat and the shaft, the pressure of the oil seal edge and the contraction force of the self-tightening coil spring will produce a certain radial tightening force on the shaft. After a period of operation, the pressure will rapidly decrease or even disappear. , Therefore, adding a spring can compensate for the self-tightening force of the oil seal at any time.
Shaft and Bore Tolerances
For more detailed information, please see the following:
Air side face The oil seal surface vertical to the center line of the shaft on the side that does not come in contact with substances to be sealed is called the back face.
Type B Oil seals
Remove the distributor cap . Before removing the distributor (See Removing and refitting the distributor ), mark the position of the rotor arm so that you can refit it just as it was.
Most ERIKS oil seals, such as the types M, MST, R and RST, are made of NBR as standard.
3) Total eccentricity
Aluminum alloys and resin (materials with a large difference between the linear expansion coefficients) demand sufficient consideration (as there is a risk of failure due to the increased clearance with the oil seal at high temperatures).
(1) Shaft speed Due to design and structural reasons, high-speed shafts should use high-speed oil seals, low-speed shafts should use low-speed oil seals, and low-speed oil seals cannot be used on high-speed shafts, and vice versa.
Many oil seals are capable of resisting contact with grease, fuel, water, and other elements. Knowing what type of fluid the seal will interact with will help you choose the right oil seal that can withstand those types of fluids.
