Abstract
The utility model relates to a double-input hoisting speed reducer. Two same input shafts are fixed on an enclosure by a conical roller bearing and fixed on a machine body by the other conical roller bearing, the machine body is connected with the fixed shaft by a bolt, a brake is connected with the enclosure by a bolt, a sun axle is connected with a shaft by a spline, and the input shafts are connected with the brake by a spine. Two same input shafts are arranged in the speed reducer, and the single input of the speed reducer is changed into double input, so that output power and torque are enlarged, and the occupation space of the speed reducer is saved when the speed reducer is used in hoisting equipment.
Description
Technical field
The utility model relates to the reductor in the mechanical equipment, specially refers to the dual input reductor of using on the winch.
Background technology
In reductor widespread use and the various mechanical equipment, generally adopt planetary gear speed-reduction in the prior art, the general gear of fixing in axial location is sun wheel, sun wheel and its engagement had not only been done revolution but also had been done the satellite gear that cries of rotation, satellite gear is on pinion carrier, output power by pinion carrier, pass to other gear again.Several gears are formed a train, and this train is called planet circular system.General planet circular system has only an input, when two or more input occurring, just can not use.And the reductor that uses on winch for satisfying its power requirement, needs the reductor more than two usually, so just usually is subjected to the restriction of space and cost.
Summary of the invention
The purpose of this utility model is to provide a kind of dual input reductor of realizing, this reductor is used in the equipment of having saved on the winch and has reduced the space.
The technical solution of the utility model is:
The dual input hoisting speed reducer, it is characterized in that: two identical input shafts are fixed on the casing by tapered roller bearing, be fixed on the body by another tapered roller bearing, body by bolted connection on anchor shaft, axle is fixed on the casing by self-aligning roller bearing, be fixed on the body by another self-aligning roller bearing, casing connects with body by bolt, drg is connected with casing by bolt, sun wheel shaft links to each other with axle by spline, axle links by flat key and gear, and gear links to each other with input shaft by gear mesh, and input shaft links to each other with drg by spline.
The utility model has changed single input of original reductor, by being set, two input shafts make single input into dual input, so just two motors can be merged into one, power merges, horsepower output and moment of torsion have been increased, save an equipment and original two spaces that reductor is occupied, saved cost.
Description of drawings
Fig. 1, the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, further specify the specific embodiment of the present utility model.
Referring to Fig. 1, two identical input shafts 41 are fixed on the casing 33 by tapered roller bearing 44, be fixed on the body 46 by another tapered roller bearing 48, body 46 by bolted connection on anchor shaft 27, axle 49 is fixed on the casing 33 by self-aligning roller bearing 36, be fixed on the body 46 by another self-aligning roller bearing 28, casing 33 connects with body 46 by bolt, drg 37 is connected with casing 33 by bolt, sun wheel shaft 59 links to each other with axle 49 by spline, axle 49 links by flat key 34 and gear 30, and gear 30 links to each other with input shaft 41 by gear mesh, and input shaft 41 links to each other with drg 37 by spline.
Because the utility model is provided with two identical input shafts in reductor, the list input of reductor is become dual input, increased horsepower output and moment of torsion, be used in and saved reductor and space in the hoisting equipment.
