Toothed chain pulling type three-grade transmission system of vertical circulating stereo garage

Abstract

The invention relates to the field of stereo garages and in particular relates to a toothed chain pulling type three-grade transmission system of a vertical circulating stereo garage. The toothed chain pulling type three-grade transmission system comprises a rack, wherein bearing seats are mounted at left and right ends of the rack; rotary shafts are inserted into the bearing seats; a linkage shaft is commonly connected between the two rotary shafts through a first shaft coupler and a second shaft coupler; a large chain wheel also sleeves a connection part of the rotary shaft at the right sideand the first shaft coupler; the rack is provide with a speed reducing motor through a motor mounting plate; the speed reducing motor is connected with a small chain wheel; a chain commonly sleeves the peripheries of the large chain wheel and the small chain wheel; a gear sleeves the periphery of each rotary shaft; a rotary table is mounted below each gear through a bracket and a rotating shaft;a tooth part at the periphery of each rotary table is engaged with the corresponding gear; a plurality of pulling plates are uniformly mounted at the periphery of one face of each rotary table throughbolts; the speed ratio value of each grade of transmission is reduced, the angle wrapping coefficient of the small chain wheel is improved, the bearing capability of the small gear is enhanced and the load of the special motor for the garage is alleviated.

Description

technical field [0001] The invention relates to the field of three-dimensional garages, in particular to a three-stage transmission system of a gear chain toggle type for a vertical circulation three-dimensional garage. Background technique [0002] The vertical circulation three-dimensional garage that provides on the market at present, the transmission mode that adopts is the chain dial type secondary transmission system. The motor directly drives the shift fork through the sprocket with a large speed ratio to drive the lifting chain. Because the rotating speed of the motor output shaft is very different from the speed at which the shift fork moves the hoisting chain, the gear ratio of the driving sprocket to the driven sprocket (or the diameter ratio of the driving sprocket to the driven sprocket) is larger. Cause the wrap angle of driving small sprocket to be too small and the load that sprocket bears is very big, simultaneously motor output shaft also must bear bigger ...

AI Technical Summary

Problems solved by technology

As a result, the wrap angle of the small driving sprocket is too small, and the sprocket bears a large load, and the output shaft of the motor must also bear a greater load

The small sprocket wears faster, the noise is louder, and the maintenance and maintenance costs are higher
