Description
Technical field
The utility model belongs to heavy-duty machinery accessory field, particularly relates to a kind of carriage walking gear box.
Background technology
Gear box, according to cellular construction module design principle, greatly reducing parts kind, is applicable to large-scale production and flexible and changeable type selecting.Decelerator spiral bevel gear, helical gear all adopt superior alloy steel carburizing and quenching, and tooth face hardness is up to 60 ± 2HRC, and flank of tooth grinding accuracy is up to 5-6 level.Transmission portion bearing all selects domestic famous brand name bearing or imported bearing, and seal selects Taiwan NAK outside framework oil seal; Sound-absorbing box body structure, larger tank surface sum big fan; Make the temperature rise of complete machine, noise reduction, maintainability is improved, and transmitted power increases.Can realize parallel axes, rectangular axis, vertical, horizontal general use casing, input mode has motor connecting flange, axle to input; Output shaft can right angle or horizontal output, has solid shafting and hollow shaft, flange plate type output shaft.Make gear box meet the installation requirement of small space, also can supply by customer demand.Its volume ratio soft tooth reduction box is little by 1/2, weight saving half, improves 3-4 useful life doubly, and bearing capacity improves 8-10 doubly.Be widely used in printing packaging machinery, multi-storied garage equipment, environmental protection machinery, conveying equipment, chemical industry equipment, metallurgical and mining equipment, iron and steel power equipment, mixing plant, road building machine, sugar industry, wind power generation, staircase elevator drive, ship domain, field of light industry, field of papermaking, metallurgy industry, sewage disposal, building material industry, hoisting machinery, pipeline, streamline etc. high-power; large speed ratio, the occasion of high moment of torsion.There is good cost performance, be conducive to the supporting of localized equipments.
Gear box is the vitals of extensive use in machine driving, during a pair gears meshing, owing to inevitably there is tooth pitch, profile of tooth equal error, can mesh impact be produced and the noise corresponding with gear mesh frequency occurs in operation process, because relative sliding also frictional noise occurs between the flank of tooth.Due to the fundamental parts that gear is in gearbox drive, reduce grating of gears very necessary to control gear case noise.In general, the reason that gear train noise occurs mainly contains the following aspects:
1. design of gears aspect.Selecting parameter is improper, and registration is too small, and profile modification is improper or do not have correction of the flank shape, and gear box structure is unreasonable.Gear Processing aspect base pitch error and profile error excessive, backlash is excessive, and surface roughness is excessive.
2. gear train and gear box aspect.Assembling is eccentric, and contact precision is low, and the depth of parallelism of axle is poor, axle, the insufficient rigidity of bearing, supporting, and the not high and gap of the rotating accuracy of bearing is improper.
3. other aspect input torques.The fluctuation of load torque, the torsional oscillation of axle system, the balance etc. of motor and other transmission.
At present, mostly tyre crane car wheel driving gearbox is the gear motor of motor and reductor direct connection, by hollow output shaft directly with install on car wheel axle.This structure driver pinion is suspended on motor shaft, and motor needs specific customization, and cost compare is expensive, and the sealing of Motor Shaft place is bad, and gear oil is easy to enter motor, causes motor damage.During product seriation design, the motor diameter of axle can be caused smaller when producing the larger gear box of speed ratio, be difficult to meet requirement of strength.Due to compact product design size, the single skeleton oil seal of the many employings of output shaft, this structure oil sealing life-span is short, often safeguard; There is no protection enclosure cover outside oil sealing, easily damage oil sealing when gear box is installed, affect sealing effectiveness.
Summary of the invention

A kind of carriage walking gear box, by motor, shaft coupling, power shaft, input pinion, input gear wheel, secondary bevel gear shaft, toggle, casting box, secondary bevel gear wheel, tertiary gear axle, export gear wheel, hollow output shaft, outside framework oil seal and V-type oil sealing are formed, motor is connected with power shaft by shaft coupling, be installed to casting box upper surface, the gears at different levels engaged successively are provided with in casting box, the axis of power shaft and the axes normal of hollow output shaft, the link position of motor and casting box adds an adpting flange, by shaft coupling, the power shaft of motor is connected with the power shaft of casting box.
Further, shaft coupling is plum blossom spring coupling, comprise the first half a coupler, the second half a coupler and quincunx elastic component, first half a coupler is connected with the power shaft of motor, described second half a coupler is connected with the power shaft of casting box, the end face of the first half a coupler and described second half a coupler is provided with quincunx double wedge, quincunx elastic component is placed between the first half a coupler and the second half a coupler, in the space between the double wedge that the petal of described quincunx elastic component is placed in described first half a coupler and described second half a coupler.
Further, the power shaft of casting box is arranged on the second half a coupler axle sleeve of shaft coupling.
Further, hollow output shaft place adds the protection gland of V-type oil sealing; Described protection gland is closely connected in imitative type with V-type oil sealing contour structures.
Beneficial effect of the present invention is:
(1) in the utility model, the link position of motor and casting box adds an adpting flange, avoids customization motor, reduces product price, reduces because of the bad risk causing leakage of oil of Motor Shaft place sealing.
(2) in utility model, shaft coupling is plum blossom spring coupling, has comparatively large, the advantage with overload protection function of torque range of compact conformation, reliable operation, transmission.
(3) power shaft of casting box is arranged on the second half a coupler axle sleeve of shaft coupling, shortens the axial dimension of power shaft, makes the structure of gear box compacter.
