Abstract
The utility model belongs to the technical field of machine tool gearboxes and particularly relates to a helical gear transmission hydraulic gap elimination device of a machine tool gearbox. The helical gear transmission hydraulic gap elimination device comprises a main shaft (8); an oil pump (9) is communicated with a one-way reducing valve (11), a revolving joint (1), an oil duct (20), an oil duct (19) and an oil cavity (15) through oil pipes; a primary helical gear (7) is fixed on the main shaft (8); a secondary helical gear (5) is sleeved on the primary helical gear (7); a positioning pin (4) is sleeved on the main shaft (8) to be contacted with the secondary helical gear (5) and is fixed on the primary helical gear (7) by bolts (17); and an adjusting block (3) is sleeved on the main shaft (8) and is tightly pressed by a locking rear cap (2). The helical gear transmission hydraulic gap elimination device of the machine tool gearbox disclosed by the utility model is simple in structure, and is convenient to adjust as the gap can be adjusted only by changing the hydraulic pressure. Therefore, processing precision of the machine tool is improved, noise in the gearbox is eliminated and stability of the whole system is improved.
Description
One, technical field:
The utility model 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 utility model is to be directed against when the lathe gearbox helical gear rotates the gap to occur, and adjustment is complicated, has designed a kind of lathe gearbox helical gear transmission hydraulic pressure backlash eliminating equipment.The utility model is intended 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).During the utility model work; 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 utility model 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:
