Abstract
The invention discloses a unidirectional suspension rubbervibration isolator for a single cylinder diesel engine. The unidirectional suspension rubber vibration isolator comprises an upper cover, a base, oilless bearings and a rubber damping element. The upper ends of the oilless bearings are fixedly connected to the bottom of the upper cover. The base is a shell body with a U-shaped groove. The U-shaped groove is internally provided with an inner sleeve, and the oilless bearings extend into the U-shaped groove of the base and form a nest structure with the base. The rubber damping element isarranged in the gap among the upper cover, the oilless bearings and the inner sleeve. According to the vibration isolator, excellent vibration performance of the rubber element is adopted, the rubberelement is sulfurized with the upper cover and the nested sleeve into one, and the functions of vertical decompression and pull are achieved. The unidirectional rubber vibration isolator has high bearing capacity, good fatigue resistance, a simple structure, and is convenient to manufacture, install and maintain.
Description
Technical field [0001] The invention belongs to the technical field of diesel engine vibration isolation, and particularly relates to a single-cylinder diesel engine unidirectional suspension rubber vibration isolator equipped with an oil-free bearing. Background technique [0002] Diesel engines have become the most widely used, most widely used, and most thermally efficient power machinery today, and they play an important role in the national economy, national defense construction and people's lives. Due to the working characteristics of diesel engines, multiple complex vibrations with different vibration sources and different modes will inevitably be generated. After mixing and superposition, the vibration of the engine will have the characteristics of broadband, multiple vibration sources and multiple main frequencies. The vibration of the engine will not only damage the components of the vehicle itself, but also deteriorate the working performance and shorten the service li...
