Problems solved by technology

[0002] The oil deflecting ring in the existing single-cylinder hydraulic cone crusher is made of nylon. Since the oil deflecting ring made of nylon is in contact with the main shaft in the single-cylinder hydraulic cone crusher, the size of the gap is difficult to control, and it cannot be blocked when the gap is large. Oil leakage, the oil leakage is very serious, and it is not known when the oil went to where
The buyer jokingly claimed that the equipment was affordable and unusable, which directly led to an increase in the cost of crushing the stone; the contact gap between the oil deflector ring made of fading nylon and the main shaft in the single-cylinder hydraulic cone crusher is small, and it is easy to generate heat so that the nylon oil deflector ring Deformed and displaced, and cannot be restored, completely unable to play the role of oil retaining
The purpose of the oil deflector ring is to prevent the lubricating oil from rising and leaking along the gap between the main shaft and the copper sleeve under pressure. However, in actual working conditions, it is found that the nylon oil deflector ring will be deformed after the temperature rises. The oil used for lubricating and cooling the main shaft leaks, and it is locked to a certain part of the main shaft, which directly loses the oil retaining effect and affects the normal operation of the equipment.
Secondly, the inner wall and bottom of the middle and lower frame of the existing single-cylinder hydraulic cone crusher are cast, and the impact resistance and toughness of the cast inner wall and bottom are relatively poor. , the huge crushing force generated between the moving cone and the crushing block has a great influence on the lower frame part. Even if the wall thickness of the lower frame part is increased, it cannot resist the strong impact force of the broken stone, often causing Occurrence of wall cracking

Embodiment 1

[0013] Embodiment 1: with reference to attached Figure 1-3 . A new single-cylinder hydraulic cone crusher, including an upper frame part 1, a middle frame part 2, a main shaft part 3, a lower frame part 4, an eccentric shaft part 5, an adjustment part 6, a transmission shaft part 14, and a small pulley 15 , small pulley taper sleeve 16, narrow V-belt 19, motor 20, shock absorber 21, shock absorber spring base 22, shock absorber spring 13, hydraulic system 9, lubrication system and electrical system, the production and installation of the above components are existing technology, which will not be described here. The inner wall of the lower frame part 4 is equipped with an organic shell guard plate 12, and the bottom of the lower frame part 4 is provided with a drive shaft sleeve guard plate 11 and a rib guard plate 10. The main body 8 of the oil deflector ring in the lower frame part 4 is The steel ring and the place where the steel ring matches the main shaft are Babbitt r...

Embodiment 2

[0015] Embodiment 2: On the basis of Embodiment 1, a dynamic sealing and impact resistance method of a new single-cylinder hydraulic cone crusher, including a single-cylinder hydraulic cone crusher, the main body of the oil retaining ring in the single-cylinder hydraulic cone crusher The babbitt alloy ring on the top is a soft phase matrix, and the hard phase particles are uniformly distributed on the annulus of the soft phase matrix. A small gap is formed between the surfaces, which becomes an oil storage space and a lubricating oil channel, which reduces friction on the main shaft, and the convex hard point supports the main shaft. The particles form lubrication, support, and sealing to avoid locking the oil deflector ring and the main shaft; when the single-cylinder hydraulic cone crusher crushes stones, the impact force it receives is transmitted to the casing on the inner wall of the lower frame and on the bottom plate When the elastic rubber layer is bonded to the guard ...

Abstract

The invention relates to a novel single-cylinder hydraulic cone crusher and a method. According to the novel single-cylinder hydraulic cone crusher, an oil retainer has good wear resistance, seizure resistance and deformation resistance and cannot damage a main shaft of the single-cylinder hydraulic cone crusher, and a lower rack part has the advantages of shock wave absorption, shock resistance, high strength and long service life. The novel single-cylinder hydraulic cone crusher comprises an upper rack part, middle rack parts, main shaft parts, a lower rack part, an eccentric shaft part, an adjusting part, a transmission shaft part, a small belt pulley, a small belt pulley taper sleeve, a narrow V belt, a motor, a damping seat, a damping spring base, a damping spring, a hydraulic system, a lubricating system and an electrical system, wherein an organic shell guard plate is arranged on the inner wall of the lower rack part; a transmission shaft sleeve protection plate and a rib protection plate are arranged at the bottom of the lower rack part; oil deflector ring bodies in the lower rack part are a steel rings; and babbitt metal rings are arranged at the matched part of the steel rings and the main shaft parts.

Description

technical field [0001] The invention relates to an oil deflecting ring which has good wear resistance, seizure resistance and deformation resistance without damaging the main shaft of a single-cylinder hydraulic cone crusher, and the lower frame part has the functions of absorbing shock waves, shock resistance and high strength. The invention discloses a novel single-cylinder hydraulic cone crusher and a method thereof with long service life, belonging to the field of single-cylinder hydraulic cone crusher manufacturing. Background technique [0002] The oil deflecting ring in the existing single-cylinder hydraulic cone crusher is made of nylon. Since the oil deflecting ring made of nylon is in contact with the main shaft in the single-cylinder hydraulic cone crusher, the size of the gap is difficult to control, and it cannot be blocked when the gap is large. Oil leakage, the oil leakage situation is very serious, and it is not known when and where the oil went. The buyer j...
