Description
Technical Field
The utility model relates to a speed reducer, concretely relates to be applied to food industry's stirring work occasion's worm gear reducer.
Background
The worm gear reducer is often used in the stirring work occasion of the food industry, and has the advantages that the slow stirring speed and the large stirring force can be provided on the premise of compact structure, but certain defects exist, so that the speed reducer is difficult to guarantee to the maximum extent to be free of leakage, and the technical problem to be solved by the existing worm gear reducer is the most urgent need.
Disclosure of Invention
Not enough to prior art exists, the utility model aims at providing a be applied to food industry's stirring work occasion, sealed reliable does not have the seepage, guarantees food sanitation's food level does not have seepage worm gear reducer.
In order to solve the technical problem, the utility model discloses an adopt following technical scheme to accomplish:
food level does not have seepage worm gear reducer machine, its characterized in that: the inner end surface of the lower rolling cone bearing is upwards protruded on the inner wall of the bottom plate of the speed reducing box body to form a boss, the inner end surface of the lower rolling cone bearing hole is provided with an inner end cover, the outer end surface of the inner end cover is provided with an outer end cover, the inner end cover and the outer end cover are fixedly connected with the speed reducing box body through screws, a first sealing ring is arranged between the inner hole of the inner end cover and the outer circle of the outer end cover, and a second sealing ring is arranged between the outer shaft of the outer end cover and the outer circle of the outer end cover; the integrative extension in bottom of outer end cover is equipped with the sleeve, the upper portion of stirring seat reduces the size and forms the cylinder, and the excircle of cylinder is located to the sleeve cover, is equipped with the third sealing ring between the two, and the top end face of cylinder sets up the fourth sealing ring with the outer axle step position that corresponds the position.
After the inner end cover is arranged on the lug boss, a solid grease storage space with a certain height is enclosed above the lower rolling cone bearing.
The lower shaft end of the inner shaft is rotatably supported by a self-aligning bearing arranged in a hole at the bottom end face of the outer shaft, and the upper shaft end of the inner shaft is positioned and supported by an output hollow shaft of the inner shaft motor.
After the technical scheme is adopted, the utility model discloses a reasonable structural design, the sealed reliable nothing seepage of speed reducer has been guaranteed to the at utmost, and when being applied to the stirring workplace of food industry, can guarantee food sanitation. The sealing working principle is as follows: the inside general solid grease that adopts of reduction box is lubricated, the lower rolling cone bearing department that most easily takes place the seepage adopts the solid grease lubrication that solid state performance is better, the upper and lower end of rolling cone dead eye is sealed by first, the second sealing ring respectively down, there is the fourth sealing ring to seal the junction of stirring seat and outer axle, the third sealing ring seals the junction of stirring seat and outer end cover in addition, the medial surface of rolling cone dead eye forms the boss at reduction box bottom plate inner wall simultaneously down, prevent that the grease in the reduction box from probably getting into rolling cone dead eye down, these all effectively improved the seepage possibility at the possible seepage position of speed reducer, thereby furthest has guaranteed that the sealed of speed reducer is reliable not had the seepage, guarantee food hygiene.
