Abstract
The utility model relates to a driving mechanism of a boring machine which solves the defects of low bearing capacity, large transmission and vibration and low precision in the prior art; a feed shaft is fixed with a worm wheel which is connected with a worm; wheel teeth on the worm are fully contacted with the wheel teeth on the worm wheel; the worm wheel envelopes the worm; the worm also envelopes the worm wheel in the full length range; the worm is meshed with the excircle and pitch circle of the worm wheel completely in the range; and the spiral teeth surfaces of the worm respectively point at the center of the worm wheel. The worm is adopted to envelope the worm wheel in the full length range to increase the amount of wheel teeth with meshing transmission, therefore, the driving mechanism improves the whole transmitting load, simultaneously improves transmitting stability, is driven by a hydraulic motor and realizes speed adjustment.
Description
Technical field
The utility model relates to a kind of boring row's driving mechanism.
Background technology
In machined, the boring arranging device is one of tooling device important in the shipbuilding, the quality of bore hole is directly connected to the quality of installation, boring row in the past adopts mechanical type, on row's axle, a big gear is installed, connect the rotation that a pin type reductor realizes arranging axle in the outside, relatively simple for structure, the processing of gear is also more convenient, but in two meshed transmission gear processes, the gear drive vibration is bigger, and the error of transmission is bigger, it is just bigger to arrange a machining accuracy that goes up boring cutter like this, is difficult to satisfy high-precision processing request.
Summary of the invention
The utility model has solved in the prior art bearing capacity the, and transmission vibration is big, and the shortcoming that precision is low provides a kind of bearing capacity big, the boring row driving mechanism that stable drive and precision are high.
Another purpose of the present utility model provides a kind of by fluid motor-driven, heightens the boring row driving mechanism of speed adjusting performance and whole stationarity.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of boring row driving mechanism, be fixed with worm gear on row's axle, worm gear is connected with worm screw, wherein, the gear teeth on the worm screw contact entirely with the gear teeth on the worm gear, and worm gear is to the worm screw envelope, in the length range of worm screw, also worm gear is carried out envelope, the cylindrical of worm and worm wheel, pitch circle are all engagements in this scope, and the spirality flank of tooth of worm screw points to the center of circle of worm gear respectively.Worm gear is to the worm screw envelope, and the whole audience scope of worm screw is interior to the full envelope of worm gear, and the helical tooth flank of worm screw all points to the center of circle of worm gear, the gear teeth quantity that participates in when making transfer motion power like this is just many, in onesize gear teeth transmission, its total transmitted load is just big, and transmits also more steady.
The two ends of worm screw are equipped with bearing, and bearing is arranged on the housing.
Worm screw is by fluid motor-driven.There is hydraulic motor to drive worm screw, can regulates output torque by the rotating speed of regulator solution pressure motor, thereby control the rotary speed of worm screw, reach the purpose of speed change.
The beneficial effects of the utility model are: adopt the interior and worm gear envelope of this worm screw length range, and the quantity of the gear teeth of increase engaged transmission, thus improve whole transmitted load, the while is the stationarity of raising transmission also, by fluid motor-driven, realizes speed governing.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model;
Among the figure: 1, housing, 2, row axle, 3, worm gear, 4, hydraulic motor, 5, worm screw, 6, bearing, 7, sealing ring.
The specific embodiment
Below by specific embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of boring row driving mechanism (referring to accompanying drawing 1), the row's of being provided with axle 2 in the housing 1, be fixed with worm gear 3 on row's axle, be fixed with worm screw 5 by bearing 6 on the housing, the two ends of worm screw are provided with sealing ring 7, the vertical mutually and engagement of worm and wheel, the gear teeth on the worm screw contact entirely with the gear teeth on the worm gear, worm gear is to the worm screw envelope, in the length range of worm screw, also worm gear is carried out envelope, the cylindrical of worm and worm wheel, pitch circle are all engagements in this scope, the spiral-shaped teeth flour pen of worm screw points to the center of circle of worm gear, and worm screw is driven by hydraulic motor 4.
Above-described embodiment is a kind of preferred version of the present utility model, is not the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
