Description
Technical Field
The utility model belongs to a living beings processing part, concretely relates to take dustproof construction's crowded material wheel part.
Background
At present, all crowded material wheels of processing living beings granule prevent through the oil blanket that the dust from getting into inside the bearing, because crowded material wheel works under high temperature, high pressure and eccentric condition, can produce a large amount of dusts simultaneously, the oil blanket damages easily, and inside the dust got into the bearing, greatly reduced bearing and crowded material wheel's life.
Disclosure of Invention
Inside for preventing that the dust from getting into oil blanket and bearing, make the life greatly reduced's of bearing and crowded material wheel not enough, the utility model provides a take dustproof construction's crowded material wheel part.
A material extruding wheel component with a dustproof structure comprises an eccentric shaft, a bearing cover, a screw, a material extruding wheel, a bearing, an oil seal, a sleeve, a grease nipple and a round nut.
The upper end of the material extruding wheel is provided with a step, and the outer circular surface of the step is provided with a left-handed dustproof groove.
The dust-proof groove is sleeved with a sleeve, and the preferable gap between the inner diameter of the sleeve and the top of the dust-proof groove is 0.01-0.05 mm.
The cross section of a preferable dustproof groove is rectangular, the groove depth is 1mm, and the groove width is 2 mm.
The dust-proof groove can effectively prevent dust from entering the bearing, prolong the service life of the bearing and improve the service life and production efficiency of equipment.
The center of the material extruding wheel is provided with a step, bearings are arranged above and below the step, and the material extruding wheel is supported on the eccentric shaft by two bearings.
The outer side of the bearing is provided with an oil seal, and the bearing and the oil seal are fixed on the extrusion wheel through a bearing cover by screws.
A round hole is formed in the middle of the top of the sleeve, threads are formed in the upper portion of the eccentric shaft, and the upper end of the eccentric shaft extends out of the round hole in the top of the sleeve and is fixed through a round nut.
The outer side of the top of the sleeve is connected with a grease nipple, an oil duct is processed in the middle of the eccentric shaft, and the grease nipple and the oil duct form a lubricating loop.
Has the advantages that:
1. the dust can be effectively prevented from entering the bearing, and the service life of the extruding wheel is prolonged by more than 2 times.
2. The working efficiency of the extrusion wheel is improved by 30-50%.
