Abstract
The utility model discloses a carborundum contact roller main shaft apparatus of a grinding-wheel gear grinding machine trimmer, wherein, a carborundum contact roller (2) is fixed at the end of a main shaft (1); the end of the main shaft (1) is nested with a sealing cover (3); an inlet channel (4) and an annular outlet channel (5) are arranged on the sealing cover (3); the annular outlet channel (5) is positioned at the lower end of the sealing cover (3) and is communicated with the outer surface of the main shaft (1); the upper end of the inlet channel (4) is of an air intake, and the lower end is communicated with the annular outlet channel (5); an annular air outlet (6) of the annular outlet channel (5) is positioned between the carborundum contact roller (2) and the sealing cover (3). Compared with the prior art, the utility model adopts the technical proposal that liquid coolant is discharged outwards when a gas proof curtain is under the functional mode, so as to protect a ball track and ensure that the matched precision of the main shaft and the bearing does not in inactivation early, thereby prolonging the service life of the trimmer.
Description
Technical field
The utility model relates to a kind of gear-grinding machine trimmer emery wheel mainshaft mechanism.
Background technology
Gear grinding machine with worm grinding wheel trimmer main shaft portion of the prior art seals imprecision always, and cooling fluid is infiltrated during work, causes the raceway wearing and tearing, and precision is lost too early, has shortened service life.
Summary of the invention
The technical problem that the utility model solves: design a kind of gear-grinding machine trimmer emery wheel mainshaft mechanism, adopt gas curtain down cooling fluid to be discharged in working order, protected raceway, prolonged service life.
Technical solution of the present utility model: a kind of gear-grinding machine trimmer emery wheel mainshaft mechanism, comprise main shaft (1), emery wheel (2), emery wheel (2) is fixed on the end of main shaft (1), the end of main shaft (1) is set with seal cover (3), be shaped on air intake duct (4) and annular exhaust duct (5) on the seal cover (3), annular exhaust duct (5) is positioned on the inwall of seal cover (3), and connect with the outer surface of main shaft (1), and the upper end of air intake duct (4) is an air inlet, the lower end is communicated with annular exhaust duct (5), and the annular air outlet (6) of annular exhaust duct (5) is positioned between emery wheel (2) and the seal cover (3).
Described seal cover (3) is positioned at the inboard of emery wheel (2), and annular exhaust duct (4) tilts laterally, and top is communicated with the lower end of air intake duct (4), and the bottom is communicated with annular air outlet (6).
The end of described main shaft (1) is outer little interior big step, be set with ball cover (8) on the little axle in the outside (7), be set with seal cover (3) on the inboard macro-axis (9), emery wheel (2) is sleeved on the ball cover (8) by the endoporus on it (10), and is fixed on the end face of macro-axis (9) by bolt (11).
Described little axle (7) is an interference fit with ball cover (8), and the endoporus (10) on the emery wheel (2) is an interference fit with ball cover (8).
The utility model compared with prior art adopts gas curtain down cooling fluid to be discharged in working order, has protected raceway, has guaranteed the unlikely premature failure of quality of fit between main shaft and the bearing, thereby has prolonged the service life of trimmer.In addition, emery wheel is by ball cover and main shaft interference fit, solved the beat problem of bad control of matched in clearance cylindrical in the past.
Description of drawings
Fig. 1 is a structure cutaway view of the present utility model,
Fig. 2 is the A portion enlarged drawing of Fig. 1.
The specific embodiment:
1,2 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.
A kind of gear-grinding machine trimmer emery wheel mainshaft mechanism, the end of its main shaft (1) is outer little interior big step, be set with ball cover (8) on the little axle in the outside (7), be set with seal cover (3) on the inboard macro-axis (9), emery wheel (2) is sleeved on the ball cover (8) by the endoporus on it (10), and is fixed on the end face of macro-axis (9) by bolt (11).Little axle (7) is an interference fit with ball cover (8), and the endoporus (10) on the emery wheel (2) is an interference fit with ball cover (8).Seal cover (3) is positioned at the inboard of emery wheel (2), be shaped on air intake duct (4) and annular exhaust duct (5) on the seal cover (3), the upper end of air intake duct (4) is an air inlet, annular exhaust duct (5) is positioned on the inwall of seal cover (3), and connect with the outer surface of main shaft (1), annular exhaust duct (4) tilts laterally, top is communicated with the lower end of air intake duct (4), the bottom is communicated with the annular air outlet (6) of annular exhaust duct (5), and annular air outlet (6) is positioned between emery wheel (2) and the seal cover (3).
Operation principle: the air inlet of air intake duct (4) upper end connects compressed air piping, compressed air forms gas curtain by annular exhaust duct (5) during work, discharge from annular air outlet (6), and then cooling fluid discharged, stop the outer surface infiltration raceway of cooling fluid by main shaft (1), guarantee the unlikely premature failure of quality of fit between main shaft and the bearing, thereby prolonged the service life of trimmer.In addition, emery wheel (2) is an interference fit by ball cover (8) and main shaft, has solved the beat problem of bad control of matched in clearance cylindrical in the past.
