Abstract
The utility model provides a clearance eliminating device of main shaft worm wheel couple of work-piece on the tooth milling lathe used to process the gear with circular arc teeth and the bevel gear. The utility model is characterized in that a work-piece box contains a horizontally mounted main shaft with a worm wheel and a worm driving the worm wheel, the hub of the worm wheel is equipped with an annular brake copper disc, the back end of the main shaft and the box are mounted with a fixing sheath between, while the circumference of the fixing sheath is uniformly arranged with screw through holes, the inner side of the fixing sheath is equipped with a brake disc with uniformly arranged blind holes on circumference, the screw holes of the fixing sheath and the blind holes of the brake disc are mounted with springs, pins and adjustable screw blocks for making the brake disc press the brake copper disc, and the screwed depth of the screw blocks can be changed to adjust the friction between the brake disc and the brake copper disc. The utility model has stable brake, easy adjustment, simple structure, small volume and low cost.
Description
Technical field
The utility model relates to a kind of spiral bevel gear milling machine bed, especially a kind of work spindle worm gear backlash eliminating equipment of spiral bevel gear milling machine bed.
Background technology
The spiral bevel gear milling machine bed is a kind of gear machining apparatus of multiple shafting, and each positioning accuracy plays crucial effects to the machining accuracy of gear, and especially the inaccurate meeting of workpiece box spindle index badly influences the precision of Gear Processing.The workpiece box spindle index drives by worm gear, but between worm gear and the worm screw certain clearance is arranged, thereby in working angles, and when the force direction of cutting workpiece is when making worm gear compress worm screw, its gap can not influence the calibration of main shaft; When the cutting workpiece force direction is that its gap will make spindle index inaccurate when worm gear and worm screw were thrown off, the machining accuracy of workpiece is reduced.The structure of present known main shaft worm gear backlash eliminating equipment is: be fixed with fixed head on cabinet wall, symmetry is installed the lever that two centres have hinge on fixed head, one end of two levers inboard the pillow plate and the brake(-holder) block thereof of hinged clamping worm gear two sides respectively, the other end installed inside of two levers has spring and the fixed axis thereof that produces clamping force.The backlash eliminating equipment shortcoming of this structure is worm gear both sides discontinuity equalizations, and the crack effect that disappears is unstable, again because casing seals, so adjust inconvenient.
Summary of the invention
The utility model provides a kind of easy to adjust, the work spindle worm gear backlash eliminating equipment of the spiral bevel gear milling machine bed that the crack that disappears is effective for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of work spindle worm gear backlash eliminating equipment of spiral bevel gear milling machine bed, by casing, level is installed in the main shaft in the casing, worm gear and wheel hub thereof on the main shaft are installed, and the worm screw that drives worm gear and main shaft rotation is formed, the side end face of described worm-wheel hub is equipped with the brake copper dish of annular, add fixed cover between rear-end of spindle and the casing, the end face of fixed cover is uniform several threaded through holes that is shaped on circumferentially, the inner face of fixed cover is equipped with the loop system Moving plate corresponding with the copper dish that brakes, the corresponding fixed cover of the medial extremity of brake disc is shaped on several blind holes, the screw thread that makes brake disc compress brake copper dish all is installed in each tapped through hole and blind hole stops up, pin and spring.
The utility model can also adopt following technical measures:
Described brake copper dish front is shaped on the grid groove that intersects in length and breadth.
Advantage and the good effect that the utlity model has are: owing to brake copper dish is installed in the worm gear side, between casing and main shaft, add the circumferentially fixed cover of uniform several screwed holes of end face, by the fixed cover screwed hole brake disc, spring, pin and the screw thread that compress brake copper dish being installed stops up, stop up the degree of depth that screws in by adjusting screw thread, change the frictional force between brake disc and brake copper dish, not only easy to adjust, and brake force equilibrium, damping balance, in addition the utility model also have simple in structure, the advantage little, that cost is low takes up room.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the C-C cutaway view of Fig. 1.
Among the figure: 1, brake copper dish; 2, brake disc; 3, fixed cover; 4, screw thread stops up; 5, pin; 6, spring; 7, worm-wheel hub; 8, main shaft; 9, casing; 10, worm screw; 11, worm gear.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, in the casing 9 of workpiece box main shaft 8 is installed, by key worm-wheel hub 7 is installed on the main shaft, on worm-wheel hub, worm gear 11 and retainer ring are installed, be equipped with on the casing and worm gear engaged worm 10 by screw.By sunk screw ring-shaped brake copper dish 1 is installed on retainer ring, the front of brake copper dish is shaped on the grid groove that intersects in length and breadth, can increase frictional force, as shown in Figure 2.By bearing fixed cover 3 is installed between rear-end of spindle and casing, the fixed cover end face is circumferentially uniform to be shaped on 6 threaded through holes.There is end face to be shaped on the loop system Moving plate 2 of 6 blind holes in the fixed cover installed inside, spring 6, pin 5 that makes brake disc compress brake copper dish and the screw thread of adjusting thereof are installed in the fixed cover tapped through hole and in the brake disc blind hole are stopped up 4, stop up the degree of depth change brake disc of screw-in and the frictional force between brake copper dish by adjusting screw thread like this, very convenient.
Claims (2)
1. the work spindle worm gear backlash eliminating equipment of a spiral bevel gear milling machine bed, by casing, level is installed in the main shaft in the casing, worm gear and wheel hub thereof on the main shaft are installed, and the worm screw that drives worm gear and main shaft rotation is formed, it is characterized in that: the side end face of described worm-wheel hub is equipped with the brake copper dish of annular, add fixed cover between rear-end of spindle and the casing, the end face of fixed cover is uniform several threaded through holes that is shaped on circumferentially, the inner face of fixed cover is equipped with the loop system Moving plate corresponding with the copper dish that brakes, the corresponding fixed cover of the medial extremity of brake disc is shaped on several blind holes, the screw thread that makes brake disc compress brake copper dish all is installed in each tapped through hole and blind hole stops up, pin and spring.
