Abstract
Disclosed is a crankshaft bearing clearance adjusting device for a press, belonging to press technical field. The crankshaft bearing clearance adjusting device comprises a crankshaft which is connected on a frame through a bearing. The outer ring of the bearing is fixedly connected with a support sleeve through a support sleeve which is provided with an inner hole and two glands arranged at two ends of the outer ring. The hole of the inner ring of the bearing is a taper hole, with the small opening facing the direction of the crank of the crankshaft. An ejector sleeve which can slide axially relative to the crankshaft is arranged on the crankshaft; the outer surface of the ejector matches with the taper hole; and the big opening end of the ejector sleeve is connected with the crankshaft through an adjusting and fixing device. The crankshaft bearing clearance adjusting device is used on a press and is simple in structure and convenient to operate and can effectively control the overall clearance of the press and improve the precision of the press.
Description
Technical field
The utility model belongs to the technical field of forcing press, relates to the crankshaft bearing gap adjusting structure of forcing press.
Background technology
The existing forcing press that has used rolling bearing that bent axle is installed, because forcing press is in the duty of pulsation vibrations significantly all the time, the bearing of bent axle in use the situation that bearing radial gap progressively increases can occur.Can cause noise increasing, machining accuracy progressively reduces, and the life-span that equipment uses shortens rapidly.
The utility model content
The utility model provides a kind of simple in structure, easy to operate at above problem, effectively controls the total backlash of lathe, improves the press crankshaft bearing clearance adjusting device of machine tool accuracy.
The technical solution of the utility model is: it comprises by bearing and is connected bent axle on the fuselage, the gland that the outer ring of bearing is provided with the support set of endoporus by one and is separately positioned on the two ends, outer ring is fixedlyed connected with support set, the hole of the inner ring of described bearing is a bellmouth, the direction of the crank throw of the osculum of bellmouth on bent axle; Being provided with on bent axle can be with respect to the cover of shirking of bent axle axial slip, and the outer surface and the bellmouth of shirking cover are suitable; The big opening end of shirking cover links to each other with bent axle by regulation fixing apparatus.
Described regulation fixing apparatus comprises adjustment support, fastening bolt, the adjusting bolt of back-up ring, spacer ring, lid shape; Spacer ring is arranged on the big opening end of shirking cover, and both ends of the surface contact with end face of shirking the big mouth of sheath end and the end face of adjusting the lid of support respectively; Adjust support and fixedly connected with the bent axle axle head, on adjustment support bottom surface, also be provided with the adjusting bolt by the fastening bolt that is arranged on the bottom surface.
Described regulation fixing apparatus comprises back-up ring, spacer ring, is used for axially fastening the fastening screw nut of spacer ring; On bent axle, be provided with a diameter less than the step of bearing construction section circle, the length of bearing construction section less than back-up ring, spacer ring, shirk the length sum of cover, the step circle is provided with the screw thread adaptive with fastening screw nut.
In the utility model, bearing is positioned at support set, and front and back are fixed with gland, adjusts support in the support set and contact with shirking to overlap by spacer ring before bent axle; Support behind bent axle, retrain by stripped nut and shirk cover, like this when stretching screw is adjusted on the support in precession, can make and shirk cover and move after relatively, bent axle moves forward relatively, thereby realizes reducing of bearing radial gap.Unclamp stretching screw, precession push-and-pull screw can be realized the increase of bearing radial gap.The utility model is applied on the forcing press, makes it simple in structure, and is easy to operate, can effectively control the total backlash of lathe, improves machine tool accuracy.
