Description
Technical field
The utility model relates to a kind of speed reducer, refers in particular to a kind of straightening machine Special worm speed reducer.
Background technique
Being still that the domestic straightening machine special reduction gear generally used adopts at present is early stage from introducing the design production technology being abroad, because the conditions of manufacture of Mechanical Industry of China at that time limited, speed reducer still has a lot of deficiency, such as: integrated carrying ability is low, box volume is huge, easy oil impregnate; Cooling effect in described casing is bad, can not bear higher heating power allowable; Lubrication effect is not good, so that working life is lower.
Summary of the invention
It is large that the purpose of this utility model is to provide a kind of thermal power, the special helical gear worm reduction gear of the reliable straightening machine of stable drive
A kind of straightening machine Special worm speed reducer, comprise a casing, an input shaft, one to be arranged in parallel with input shaft and to drive the worm screw of rotating and the worm gear be meshed with worm screw by input shaft, the input end of described input shaft installs small gear, the gearwheel be meshed with small gear installed by one end spline of worm screw, in worm gear, hollow output shaft installed by involute splines, described casing is double-deck water flowing casing, casing is arranged cooling water intake and coolant outlet, the sheathed water-throwing disk for preventing cooling water from oozing out speed reducer of output terminal of input shaft.
The input end of the input shaft of described straightening machine Special worm speed reducer stretches out casing outside, and between input end and casing, arrange input transparent cover, and the end face of described water-throwing disk abuts and is sealed on outside input transparent cover.
The described worm screw of described straightening machine Special worm speed reducer is supported in casing by tapered roller bearing, described input shaft is erected on casing by rolling bearing, the two ends of output hollow shaft all arrange bearing support, install tapered roller bearing in bearing support, bearing support outer end all exports transparent cover by screw fixed installation.
The described cooling water intake of described straightening machine Special worm speed reducer is arranged on the input end of corresponding input shaft on casing, described coolant outlet is arranged on the output of corresponding input shaft on casing, and on casing, the output bolt of corresponding input shaft connects the cover plate of gearwheel and small gear described in capping.
The beneficial effects of the utility model are: arrange double-deck water flowing casing, and at the sheathed water-throwing disk for preventing cooling water from oozing out speed reducer of the output terminal of input shaft, both improve the thermal power of speed reducer, can prevent again extraneous steam from entering speed reducer, affect working life, cooling water also can be avoided to ooze out from the output terminal of input shaft and affect cooling effect; In worm gear, hollow output shaft installed by involute splines, makes speed reducer drive steadily reliable.
Accompanying drawing explanation
