Description
Technical Field
The utility model relates to a novel single-cylinder hydraulic cone crusher, which has an oil retainer ring with good wear resistance, seizure resistance and deformation resistance and can not damage a main shaft of the single-cylinder hydraulic cone crusher, and a lower frame part with shock wave absorption, shock resistance, high strength and long service life, and belongs to the field of single-cylinder hydraulic cone crusher manufacturing.
Background
The oil slinger in the existing single-cylinder hydraulic cone crusher is made of nylon, and the oil slinger made of nylon is in clearance contact with a main shaft in the single-cylinder hydraulic cone crusher, so that the size of the clearance is difficult to control, the oil cannot be blocked from leaking when the clearance is large, the oil leakage condition is very serious, and the oil is not known to run to where the oil is to go. Buyers play with the devices to afford and not use, which directly results in the increase of the cost of crushing stones; when the contact clearance between the oil slinger made of the fading nylon and the main shaft in the single-cylinder hydraulic cone crusher is small, heat is easily generated to deform and displace the nylon oil slinger, and the nylon oil slinger cannot recover and completely cannot play a role in oil slinging. The purpose of the oil deflector is to prevent lubricating oil from overflowing and leaking along the gap between the main shaft and the copper sleeve under the action of pressure, but the nylon oil deflector can deform after the temperature is raised in actual working conditions, so that the oil leakage for lubricating and cooling the main shaft cannot be prevented, and a certain part is locked with the main shaft to directly lose the oil deflector effect and influence the normal operation of equipment. Secondly, the inner wall and the bottom of the lower frame part of the existing single-cylinder hydraulic cone crusher are cast, and the impact resistance and the toughness of the cast inner wall and the cast bottom are relatively poor, so that for the cone crusher for crushing large stones, the huge crushing force generated between the movable cone and the crushing stones has great influence on the lower frame part, even if the wall thickness of the lower frame part is increased, the strong impact force of the stones cannot be resisted, and the wall cracking phenomenon is often caused.
Disclosure of Invention
The design purpose is as follows: the defects in the background art are avoided, the oil deflector ring is designed to have good wear resistance, seizure resistance and deformation resistance, and the main shaft of the single-cylinder hydraulic cone crusher cannot be damaged, and the lower frame part of the oil deflector ring has the advantages of absorbing shock waves, resisting shock, being high in strength and long in service life.
The design scheme is as follows: in order to achieve the above design objectives. The utility model has the structural design that: 1. the utility model discloses a single-cylinder hydraulic cone crusher, which is characterized in that a shell guard plate is arranged on the inner wall of a middle lower frame part of the single-cylinder hydraulic cone crusher, and a transmission shaft sleeve guard plate and a rib guard plate are arranged at the bottom of the lower frame part. The purpose of this design is: because the elastic adhesive is cured by light, heat or moisture and has rubber elasticity and bonding strength, when the elastic adhesive is used as the adhesive of the shell guard plate, the transmission shaft sleeve guard plate, the rib guard plate and the lower frame part, the impact resistance of the bonded lower frame wall and the bonded bottom plate is improved by more than one time compared with the impact resistance of the existing lower frame part, because the impact force generated when a large stone is crushed between the movable cone and the crushing wall is transmitted to the lower frame part through the shell guard plate and the rib guard plate, the elastic adhesive layers positioned between the shell guard plate, the rib guard plate and the wall and the bottom (bottom plate) of the lower frame part can greatly absorb and slowly release the impact force, thereby greatly reducing the impact on the lower frame part. In a similar way, the rubber layer formed after the transmission shaft sleeve guard plate and the lower frame part are bonded by the elastic adhesive can absorb and release the influence of the transmission shaft part on the lower frame part. 2. The utility model relates to a design that an oil deflector ring main body in a single-cylinder hydraulic cone crusher is a steel ring, and a babbitt metal ring is arranged at the matching part of the steel ring and a main shaft, which is the second technical characteristic of the utility model. The purpose of this design is: the babbit alloy has the structural characteristics that hard phase particles are uniformly distributed on a soft phase matrix, the soft phase matrix enables the alloy to have good embedding property, compliance and seizure resistance, after the babbit alloy is ground in, the soft matrix is concave, the hard particles protrude outwards, a tiny gap is formed between sliding surfaces, an oil storage space and a lubricating oil channel are formed, friction reduction is facilitated, and the convex hard particles play a role in supporting and bearing. Therefore, after the Babbitt metal ring is embedded at the matching part of the oil retainer main body and the main shaft, oil in an oil storage space formed by a small gap on a contact surface between the Babbitt metal ring and the main shaft in the single-cylinder hydraulic cone crusher can lubricate the main shaft and also can seal the main shaft, so that the problem of oil leakage in the background technology is solved well, and the normal operation of equipment is ensured. Most importantly: when 6-8Kg of oil pressure seal is formed between the oil retainer ring and the main shaft, an oil film with pressure is formed between the main shaft and the shaft sleeve, and the oil film ensures that the main shaft and the shaft sleeve cannot be in direct contact and cannot be relatively abraded, so that the service lives of the main shaft and the shaft sleeve are greatly prolonged. 3. The design that the Babbitt alloy ring is embedded on the oil retainer main body and the ring opening of the Babbitt alloy ring is smaller than that of the oil retainer main body is the third technical characteristic of the utility model. The purpose of this design is: because the oil slinger main body is made of steel, if the steel oil slinger contacts with a main shaft in the single-cylinder hydraulic cone crusher, the oil slinger is influenced by the performance of the steel material, the oil slinger cannot prevent the lubricating and cooling oil of the main shaft from leaking, and the surface of the main shaft can be damaged. Therefore, when the collar mouth of the Babbitt metal ring is smaller than that of the oil deflector main body, the contact between the steel oil deflector main body and the main shaft can not occur, and the surface of the main shaft can not be damaged.
The technical scheme is as follows: the utility model provides a novel single cylinder hydraulic pressure cone crusher, includes upper portion rack portion, middle part rack portion, main shaft portion, lower part rack portion, eccentric axial region, adjustment portion, transmission axial region, belt lace wheel taper sleeve, narrow V area, motor, shock mount, damping spring base, damping spring, hydraulic system, lubricating system and electrical system, the upper portion of lower part rack portion inner wall has the shell backplate, and transmission shaft cover backplate and muscle backplate have been put to lower part rack portion bottom, and the oil scraper ring main part in the lower part rack portion is steel ring and main shaft cooperation department are the babbitt alloy ring.
Compared with the background technology, firstly, the sealing ring which adopts the bus alloy ring as the oil retainer ring has good wear resistance and sealing performance, and good seizure resistance, and the locking of the oil retainer ring and the main shaft can not occur; secondly, when the babbit alloy is matched with the main shaft in a friction sealing manner, the main shaft is not damaged, the problem of oil leakage of the main shaft is well solved, meanwhile, the oil retainer does not deform per se, the service life is long, and in actual use, the service life of the oil retainer is more than 10 times that of the prior art; thirdly, the inner wall of the lower frame part is provided with a machine shell guard plate by adopting elastic adhesive, and the bottom of the lower frame part is provided with a transmission shaft sleeve guard plate and a rib guard plate by adopting elastic adhesive, so that the shock resistance of the lower frame part is fundamentally changed, the working performance of the whole machine is improved, and the service life of the whole machine is prolonged by multiple times.
