Abstract
The utility model discloses a waterproof structure of a hot rolling speed reducer. A box waterproof structure and an output shaft waterproof structure are arranged on a speed reducer, the box waterproof structure comprises a vent plug (8), a first side plate (9) and a second side plate (10), the first side plate (9) and the second side plate (10) are arranged on a box body (7) at the side of an output shaft (13), the first side plate (9) and the second side plate (10) form a thermal insulation cavity, and the vent plug (8) is arranged on the thermal insulation cavity. The output shaft waterproof structure comprises a first oil seal (1), an insulated ring (2) and a second oil seal (3), the first oil seal (1) is arranged on the output shaft (13) in the forward direction, the second oil seal (3) is arranged on the output shaft (13) in the reverse direction, and the insulated ring (2) is arranged between the first oil seal (1) and the second oil seal (3). The waterproof structure of the hot rolling speed reducer is simple in structure, convenient to install, and capable of effectively preventing the speed reducer from being affected by cooling water and steam generated during hot rolling, and prolonging the service life of the speed reducer.
Description
Technical field
The utility model relates to reductor, is specifically related to the waterproof construction of metallurgy industry hot rolling reductor.
Background technology
At present on the hot rolling line of the metallurgical steel pipe of China, steel plate factory, design rolling operation of carrying out simultaneously with cooling, rolling drive disk assembly is reductor, if the installation site of reductor is below the milling material or tiltedly, cool off the inner chamber that water and steam just enters into reductor easily so, gear and bearing in the corrosion casing destroy lubricating oil.Therefore the good and bad normal use influence to this type of hot rolling line of the waterproof construction of reductor design is very big.
Structurally there is following defective in traditional reductor: 1, casing is one-sided plate, can produce water smoke at cabinet wall when internal-external temperature difference is big; 2, the hermetically-sealed construction at output shaft place can not stop cooling water and steam to enter in the reductor casing reliably.The problems referred to above all can make gear, the bearing corrosion of reductor, and the emulsification of lubricant in the casing finally causes the hot rolling line cisco unity malfunction.
Summary of the invention
The purpose of this utility model is: the waterproof construction that a kind of hot rolling reductor is provided, adopt this waterproof construction can effectively completely cut off the outer cooling water of reductor and steam enters, make reductor by the influence of external world cooling water and steam, guarantee that the lubricating oil in the reductor casing is not emulsified, gear and bearing be by corrosion.
Technical solution of the present utility model is: this reductor comprises casing and output shaft, output shaft is installed on the bearing block of casing through bearing block and bearing, end cap is installed on the bearing block, lubricating cup is installed on the end cap, it is characterized in that: casing waterproof construction and output shaft waterproof construction are installed on the reductor, described casing waterproof construction comprises porous plug, a side plate and No. two side plates, casing in the output shaft side is installed a side plate and No. two side plates, a side plate and No. two side plates form heat-insulation chamber, and porous plug is installed on the heat-insulation chamber; Described output shaft waterproof construction comprises oil sealing, spacer ring and No. two oil sealings No. one, and forward is installed an oil sealing on the output shaft, and No. two oil sealings oppositely are installed on the output shaft, between an oil sealing and No. two oil sealings spacer ring is installed.
Wherein, in the end cap outside baffle plate is installed.
Wherein, process groove on the output shaft, rubber ring is installed in the groove.
The utlity model has following advantage: 1, the positive and negative installation double oil seal in output shaft place, wherein an oil sealing formal dress prevents leaking of the inner oil product of reductor, the another oil sealing is counter to be adorned, and prevents entering of extraneous water and steam; 2, spacer ring is installed between double oil seal, is made things convenient for lubricating grease from lubricating cup, to add, avoid oil sealing and output shaft dry friction; 3, baffle plate is installed in the end cap outside, and the slit of baffle plate and output shaft is blocked by rubber ring, plays the effect of dash; 4, casing adopts dual-sided board, causes internal-external temperature difference too high when preventing extraneous water and steam invasion and attack reductor, forms fog at the reductor inwall and produces the globule; 5, porous plug is installed between dual-sided board, is guaranteed pressure and ambient pressure balance between dual-sided board; 6, simple in structure, easy for installation, the high-temperature cooling water that produces in the time of effectively stopping hot rolling and steam have prolonged the service life of reductor and lubricating oil to the influence of reductor.
