Gear reduction is equipped in roller box body, is equipped with rotor and motor output shaft in motor, motor output shaft end have tooth form and
The end is meshed with gear reduction；Gear reduction includes the gear shaft and the output that are arranged on reduction gear casing
Axis, gear shaft is coordinated by axle key to be connect, and gear shaft is meshed equipped with tooth form with secondary gear with one-stage gear, secondary gear
Wheel is connected with exporting axis by axle key cooperation, and above-mentioned one-stage gear is meshed with the toothed end of motor output shaft；Level-one tooth
Wheel and secondary gear are helical gear；Bearing is equipped between gear shaft and output shaft and reduction gear casing.But this subtract
Fast machine is driven that torsion is smaller, and power is larger needed for motor in use, and transmission system is complex, and use is in ship
Shi Rongyi suffers erosion, and service life is shorter.
Utility model content
The utility model is to provide a kind of straight parallel peculiar to vessel and hands over double output shaft speed reducer, mainly solves prior art institute
Existing speed reducer is driven that torsion is smaller, and power is larger needed for motor in use, and transmission system is complex, and makes
Easily suffer erosion during used in ship, service life it is shorter wait the technical issues of.
The above-mentioned technical problem of the utility model is mainly what is be addressed by following technical proposals：
The straight parallel peculiar to vessel of the utility model hands over double output shaft speed reducer, and including housing, the housing is equipped with input
Flange, input flange is interior to be equipped with input shaft, and input shaft is connected with parallel output shafts by gear pair, and input shaft also passes through bevel gear
Pair is connected with straight friendship output shaft, and the straight outer end for handing over output shaft is connected with shaft coupling, and the middle part of shaft coupling outer circle is equipped with bulge loop, shaft coupling
The bore section of device is equipped with step.Output shaft is orthogonal sets up for the parallel output shafts of the utility model and straight friendship, by two-way
Vertical output, transmission torsion increase, power of motor can reduce, and simplify transmission system, average transmission efficiency is 94%, can be obtained
The fast ratio of bigger.Step, the various sizes of output shaft that can transfer, input power equipment are set at the endoporus of shaft coupling.
Preferably, straight friendship output flange is connected on the housing, and it is straight that output flange is handed over to be fixed with transfer tube, it transfers
The outer surface of pipe is fixed with hanging ring.Straight that output shaft is handed over to be located in transfer tube, transfer tube can ensure directly output shaft to be handed over to be not easily susceptible to
Dust invades.
Preferably, the outer end of the transfer tube is fixed with coupling flange, one end of coupling flange is equipped with boss,
The other end of coupling flange is equipped with annular groove.The both ends of coupling flange set boss and groove respectively, in this way its with
Sealing performance is higher when distinct device connects.
Preferably, be provided with dovetail groove on the inner wall of the shaft coupling, embedded with sealing element in dovetail groove, sealing element with
Cavity is provided on the straight contact surface for handing over output shaft, the opening width of cavity is less than its inner width.It can be prevented by sealing element
The only intrusions such as dust, seawater, while the ductility of sealing element can be strengthened by cavity, it can adapt to the temperature of marine climate in this way
Degree variation.
Therefore, the utility model is by two-way vertical output, and transmission torsion increase, power of motor can reduce, simplified to pass
Dynamic system, using being not easy to receive erosion in ship, service life is longer, simple and reasonable for structure.
