One or two grades of herringbone bears 10, opposite side is equipped with low speed bearing 12, and breather valve 8 and hoisting ring 9, top box are provided with the top of upper box 11
Fixed by connecting bolt 17 between body, middle casing and lower box.
1st, speed increaser casing：
This gear speeder is to carry out improvement and design under the basic installation form of original planet gear speeder to be fabricated by,
Thus there is alignment, be input into output shaft on the same axis, and horizontal installation position is any limitation as, and fast ratio also compares
Greatly, speed increaser cabinet design, into the casing of upper, middle and lower three, is driven by two-stage and reaches demand in this case, is easy to peace
Dress and maintenance.Centre-to-centre spacing is reduced as far as possible in the case where design strength is allowed, so as to lower the center of gravity, in order to avoid when speed increaser runs
Generation is rocked, and middle casing and upper box are tried one's best reduction weight, it is to avoid top-heavy phenomenon.Carried out after the casing casting of upper, middle and lower
Eliminate stress treatment, blasting treatment, after roughing and carry out it is secondary elimination stress treatment.
2nd, gear drive group：
Same axis input, the gear speeder of output have alignment, and gear drive group will be using the shape of dispensed in parallel
Formula, is in the parallel distribution of "Ji" type using the axle of two groups of teeth wheel three according to actual installation situation.One-level is employed to reduce axial force
Spur Gear Driving, two grades of herringbone bear transmissions；Gear shaft assembly and high speed shaft have carried out component dynamic performance test.
3rd, Gearmaking Technology：
Gear uses carburizing and quenching material in itself, in order to scale removal and raising gear surface accuracy class are carried out to it
Grinding flank of tooth treatment, in order that mesh stiffness relatively eases up, reduce due to base pitch error and stand under load deformation it is caused it is engaging-in with
Nibbling out impact or improving lubrication of tooth surface state prevents glued generation, original involute profile in tooth top or close to root circle
A part is repaiied at the position at angle, makes the flank profil at this no longer be involute shape, carries out mending teeth of gear.Gear uses hard tooth
Face, 5 grades of accuracy class, teeth portion carburizing and quenching.
Manufacture of the present utility model is installed and used
1. the processing of casing.The depth of parallelism and axiality are required between the bearing hole of each connection.Processing bearing hole is in coordinate
Carried out on boring machine, coaxial bearing hole is disposably machined, it is complete that the tolerance required according to centre-to-centre spacing in the depth of parallelism beats coordinate
Into machining accuracy uniformity is very high.
2. the base tangent length and variation of gear will directly affect each pair of meshing backlass of gear, the position of engagement and nibble
DYNAMIC DISTRIBUTION with joint efforts.Therefore, strictly to control base tangent length and tolerance in tooth processed.In the margin of tolerance, common normal is most
Amount is consistent, particularly herringbone bear, to ensure that gear has preferable sideshake uniformity, common normal inconsistency general control
Within 0.02mm.
3. the utility model speed increaser constitutes speed increaser main body by the casing of upper, middle and lower three, and the tooth being driven by two-stage
Wheel assembly is constituted.Slow-speed shaft engages the second spur gear on jackshaft, the on jackshaft the 1st by the first Spur Gear Driving
The two or two grade of herringbone bear on level herringbone bear transmission engagement high speed shaft, drives high speed shaft.Compact conformation is reasonable, with enough
Intensity, rigidity, good stability is safe and reliable, easy to operate.
