Problems solved by technology

Under the action of hydrostatic pressure, the journal and the working surface of the bearing are completely separated by a layer of oil film, which can reduce the friction resistance between the journal and the bearing when working, reduce the temperature rise and eliminate wear, increase the speed of the rotating shaft, and support the vertical shaft The life of the system; but the use of hydrostatic bearings requires a special oil supply system, and the cleanliness of the lubricating oil is required to be high. It is mainly used in various machine tools, high-speed light-loaded small and medium-sized machine tools and equipment, speed Machine tools and equipment with low self-weight and large weight, machine tools and equipment with a certain external load direction, and high-precision machine tools and equipment
However, heavy machinery such as vertical shaft impact crushers with high speed, heavy load, vibration, uncertain load direction and poor working environment have not been popularized and applied.

Embodiment

[0027] Embodiment: A vertical shaft support system for a vertical shaft impact crusher, comprising a vertical shaft support box, a vertical shaft is arranged on the vertical shaft support box, and an upper end cover and a lower end are respectively connected to the upper end and the lower end of the vertical shaft support box Cover; the hydrostatic bearing supporting the vertical shaft is installed in the bearing seat of the vertical shaft supporting seat box and the upper end cover; the performance of the vertical shaft is improved by utilizing the characteristics that the speed of the hydrostatic bearing has nothing to do with the load and the characteristics of resistance to shock and vibration Support conditions, thereby greatly improving the rotor speed, bearing life and adaptability to continuous random vibration of the vertical shaft impact crusher. The oil supply system of the hydrostatic bearing installed at the same time is a stable flow oil supply system.

Abstract

The invention publishes a vertical shaft supporting system of the vertical spindle type crusher and its vertical shaft fulcrum arrangement, including the vertical shaft support abutment box body, the vertical shaft installs on the vertical shaft support abutment box body, in the upper extreme and the lower extremity of the vertical shaft support abutment box body separately connects the superior cover and the interior cover; liquid hydrostatic bearing which supports the vertical shaft all install on the support abutment box body and the bearing seat of the superior cover. The invention replaces the rolling bearing of the supporting vertical shaft in the existing vertical spindle type crusher by using the liquid hydrostatic bearing, and uses the characteristic of the liquid hydrostatic bearing to improve the supporting condition of the vertical shaft, thus enhances the rotor speed, the bearing life and to compatibility of the continuance random vibration of the vertical spindle type breaker.

Description

technical field [0001] The invention relates to a vertical shaft impact crusher, in particular to a vertical shaft support system and a vertical shaft support device of the vertical shaft impact crusher. Background technique [0002] The vertical shaft impact crusher relies on the high-speed rotation of the rotor, and uses the rotor blades to accelerate the linear velocity of the materials entering the rotor from zero to 60-80 meters per second, and then throws the materials out from the ejection port of the rotor blades to move at high speed. After the material breaks away from the rotor, it hits the anvil in the crushing chamber, disintegrates itself and releases energy to achieve crushing. Because the greater the speed of the impacting material, the more complete the disintegration and the more thorough the crushing, so the rotor speed is the decisive factor of the crushing capacity of the vertical shaft impact crusher. At the same time, because the particle size, qualit...
