Abstract
The invention belongs to the technical field of speed changing boxes of machine tools, in particular relates to a helical gearing hydraulic gap-eliminating device of a speed changing box of a machine tool. The helical gearing hydraulic gap-eliminating device comprises a main shaft (8), wherein an oil pump (9) is communicated with a one-way reducing valve (11), a rotary joint (1), an oil duct (20), an oil duct (19) and an oil cavity (15) through an oil pipe, a main helical gear (7) is fixed on the main shaft (8), an auxiliary helical gear (5) is sleeved on the main helical gear (7), a location pin (4) is sleeved on the main shaft (8) to be in contact with the auxiliary helical gear (5) and fixed on the main helical gear (7) by using a bolt (17), and a regulating block (3) is sleeved on the main shaft (8) and pressed by using a locking back cap (2). The helical gearing hydraulic gap-eliminating device has a simple structure, is convenient for regulation so that a gap can be regulated by only changing hydraulic pressure, thus processing precision of the machine tool is increased, noise in a gear casing of the gear is eliminated, and stability of the whole system is improved.
Description
One, technical field:
The invention belongs to the lathe gearbox technical field, particularly a kind of lathe gearbox helical gear transmission hydraulic pressure backlash eliminating equipment.
Two, background technique:
What lathe gearbox helical gear backlash eliminating equipment was used usually at present is axial shimming adjustment method and axial stage clip adjustment method.Axially shimming adjustment method is adjusted very complicated; Axially stage clip is adjusted method, and required axial dimension is big.These two kinds of methods are when gear box structure is compact, and the adjusting play is very inconvenient.
Three, summary of the invention:
The gap occurs when The present invention be directed to the rotation of lathe gearbox helical gear, adjustment is complicated, has designed a kind of lathe gearbox helical gear transmission hydraulic pressure backlash eliminating equipment.The present invention intends the technological scheme of taking: a kind of lathe gearbox helical gear transmission hydraulic pressure backlash eliminating equipment; It is made up of main shaft (8), it is characterized in that oil pump (9) links to each other with one way pressure-reducing valve (11) through oil pipe, and one way pressure-reducing valve (11) links to each other with swivel coupling (1) through oil pipe; Swivel coupling (1) is connected with the axial oil duct (20) of main shaft (8); Axially oil duct (20) is connected with radial direction oil (19), and radial direction oil (19) is connected with oil pocket (15) through the hole of radially opening on the main helical gear (7), and main helical gear (7) is fixed on the main shaft (8) through driving key (16); Auxilliary helical gear (5) is enclosed within on the main helical gear (7); Between auxilliary helical gear (5) and the main helical gear (7) oil pocket (15) is arranged, be fixed with seal ring (14) on the auxilliary helical gear (5), be fixed with seal ring (6) on the main helical gear (7); Locating stud (4) is enclosed within main shaft (8) and upward contacts with auxilliary helical gear (5); And be fixed on the main helical gear (7) with bolt (17), adjustment piece (3) is enclosed within main shaft (8) and goes up and contact with locating stud (4), and locking back of the body cap (2) is upward at main shaft (8) upward and compress locating stud (4).When the present invention works; Hydraulic oil arrives one way pressure-reducing valve (11) through pump (9); Through pressure relay (12) detected pressures, arrive swivel coupling (1) again, arrive in the chamber between main helical gear (7) and the auxilliary helical gear (5) through main shaft; Auxilliary helical gear (5) can slide along the helical gear flank of tooth on main helical gear (7), thereby eliminates helical gear gap.The present invention is simple in structure; Easy to adjust, only needing to change hydraulic pressure just can the adjusting play, thereby improves machine finish and eliminated the noise in the gear-box; Improved the stability of whole system; Need not open gear shift cover when having solved helical gear and having the gap, need not remove correlated parts, just can solve the helical gear crack problem that disappears.
Four, description of drawings:
Fig. 1 is a structural representation of the present invention
Fig. 2 is Figure 1A-A sectional view
Fig. 3 is a hydraulic principle schematic representation of the present invention
Among the figure: 1, swivel coupling 2, locking back of the body cap 3, cushion block 4, locating stud 5, auxilliary helical gear 6, seal ring 7, main helical gear 8, main shaft 9, oil pump 10, relief valve 11, one way pressure-reducing valve 12, pressure gauge 13, pressure relay 14, seal ring 15, oil pocket 16, driving key 17, screw 18, seal ring 19, radial direction oil 20, axial oil duct
