Abstract
The invention relates to a spin forming method without inner ring action for an integral self-lubricating joint bearing. The method is characterized by comprising the following steps of: firstly attaching a self-lubricating layer to the inner surface of an outer ring blank; placing a bearing inner ring in the outer ring blank to which the self-lubricating layer is attached; casing the bearing inner ring on a floating shaft; clamping the outer ring blank by using a chuck on a spinning machine; driving the bearing outer ring blank to rotate at a high speed by the chuck; performing feeding motion according to given spinning process parameters of a spinning wheel; when the spinning wheel reaches a set target position, finishing spin forming; and grinding the end face and the outer surface of the bearing to obtain a self-lubricating joint bearing finished product. The method has the advantages that: during forming and assembly of the outer ring, no locking and extrusion effects are formed between the bearing outer ring and the bearing inner ring; the influence of a manufacturing process on the self-lubricating layer is small; the bearing has a bearing clearance which meets the requirements of the finished bearing after being formed; and the spin forming is uniform in deformation, small in deformation force and easy to control. The rate of finished products, the bearing life and the reliability of the joint bearing manufactured by using the method are obviously improved.
Description
Technical field
The invention belongs to oscillating bearing and make field, particularly a kind of oscillating bearing manufacturing process.
Background technology
At present, known self-lubricating knuckle bearing is made up of the inner ring of a band spherical outside surface, the outer ring and the self-lubricating layer of a band Internal Spherical Surface.Version by the outer ring is divided into: single seam formula, double slit formula, two half formula and monoblock type; The self-lubricating layer of Internal Spherical Surface is the key function structure of bearing in the outer ring; Not damaged and formation meet the gap condition of finished product bearing requirement in the manufacturing, and its performance is played decisive role.Though the manufacturing of single seam formula self-lubricating knuckle bearing inner surface is simple; Can inner ring directly be pressed in the outer ring of cracking during assembling; But very easily cause the damage of inner surface self-lubricating layer and inner ring outer surface, in addition, in the use; Cause unbalance stress because of cracking, bearing life and reliability are reduced; Double slit formula self-lubricating knuckle bearing; Though to the lubricating layer not damaged, outer ring and self-lubricating layer surface are subdivisions in making, in use the structure of non-integral makes inhomogeneous, the discontinuity in gap; Double slit formula lubricating layer and bearing reliability thereof are lower, the assembly structure relative complex; In addition; Two half formula self-lubricating knuckle bearings are connected two semi outer rings by some bolts, complex structure, matching requirements height; Two semi outer rings and self-lubricating layer surface also are the structures of non-integral; Inhomogeneous, the discontinuity in gap, and this structure is not suitable for small-sized self-lubricating knuckle bearing, and reliability is low.
The outer ring of monoblock type self-lubricating knuckle bearing and self-lubricating layer are overall structure, and outer ring and inner ring are simple in structure, and the gap condition meets the requirement of finished product bearing; Reliability is high in the use, but on the existing manufacturing technology, the outer ring is to be formed on the inner ring with the forging method envelope; When the outer ring was shaped, at first inner ring was enclosed within on the axle, the outer ring blank was enclosed within outside the inner ring again; Suppress the outer ring then, make on the spherical outside surface of inner surface locking inner ring, then the machined outer ring; Through the control axle magnitude of interference [" bearing " 1973, (6)], make to produce the gap between lubricating layer and the inner ring outer surface; Be the self-lubricating knuckle bearing play, in monoblock type self-lubricating knuckle bearing manufacture process, for forming outer ring Internal Spherical Surface and the bearing clearance that meets the requirement of finished product bearing; Self-lubricating layer stands twice violent extruding heterogeneous and distortion; Self-lubricating layer very easily causes the conquassation damage, and the finished product rate is not high, the self-lubricating layer reliability is not high, so the exploitation of no inner ring effect forming technique is necessary in the manufacturing of monoblock type self-lubricating knuckle bearing.
Summary of the invention
The object of the present invention is to provide a kind of no pressure effect between outer ring blank inner surface and inner ring spherical outside surface in manufacture process; Little to the self-lubricating layer influence, the monoblock type self-lubricating knuckle bearing that has the bearing clearance that meets the requirement of finished product bearing after the shaping does not have inner ring effect spin forming method.
The object of the invention can be realized through following technical proposals:
A kind of spin forming method of monoblock type self-lubricating knuckle bearing that comprises bearing inner race, bearing outer ring and stick to the self-lubricating layer of bearing outer ring inner surface; Be earlier self-lubricating layer to be affixed on outer ring blank inner surface; Bearing inner race is placed the outer ring blank that is stained with self-lubricating layer, bearing inner race is enclosed within on the floating axle of spinning machine; Then, on spinning machine, clamp the outer ring blank with chuck, chuck drives the bearing outer ring blank and rotates at a high speed, and spinning wheel carries out feed motion according to given rotary pressure process parameter, and the outer ring blank is carried out spinning; When the target location that spinning wheel arrival is set, mould pressing is accomplished; At last, through to its end face and the processing of outer surface car mill, obtain the self-lubricating knuckle bearing finished product again.
Method of the present invention is through accurate Control Shaft bearing outer-ring blank shape and rotary pressure process parameter; The spinning inner surface is stained with the outer ring blank of self-lubricating layer; Make its inner surface gradually plastic deformation be sphere, form the bearing clearance meet the finished product requirement, realize the bearing assembling simultaneously; No locking squeezing action can not cause damage to self-lubricating layer between bearing outer ring and the bearing inner race.
In said forming process; The mould pressing and the assembling that are stained with the solid box inner surface of self-lubricating layer are carried out simultaneously; And after bearing outer ring mould pressing and assembling; Outer ring blank inner surface just becomes Internal Spherical Surface, and the outer ring blank can not produce the locking squeezing action to the bearing inner race spherical outside surface.
The present invention compared with prior art has the following advantages: solved the problem that existing monoblock type self-lubricating knuckle bearing outer ring is shaped and assembling influences self-lubricating layer; In the outer ring is shaped and assembles; No locking and squeezing action between bearing outer ring and bearing inner race; Little to the self-lubricating layer influence in manufacture process, have the bearing clearance that meets the requirement of finished product bearing after the shaping, the mould pressing distortion is even, plastic force is little, be easy to control.The yield rate of this manufacturing approach, bearing life and reliability all have obvious lifting.
