Description
Technical field
The present invention relates to a kind of spherical outside surface four-point contact ball bearing of usheing to seat, belong to the spherical outside surface rolling bearing technical field of usheing to seat.
Background technique
The spherical outside surface rolling bearing of usheing to seat is made up of bearing with spherical outside surface and spherical bearing block two-part, its working principle and other deep groove ball bearing are basic identical, but the outer ring of this bearing is sphere with bearing support to be contacted, and has formed active state freely, makes bearing can realize the self-aligning function.
Its characteristics are: this bearing supply in full sets of can usheing to seat, and along with the development of this bearing, the special manufacturer of bearing with spherical outside surface seat has also appearred simultaneously, so adopt this bearing support design and processing, can shorten the cycle greatly, reduce cost; The bearing two ends all adopt rubber seal and high-quality cold rolled steel to sigh the dust-proof cover double-layer seal, and sealability is reliable, are applicable to stir up a cloud of dust, work in the environment that muddy water splashes; When Bearing Factory assembles, the dual-purpose fat of high-quality anti-rust and lubrication of bearing filling capacity, under general load average service conditions, bearing whole useful life period, need not refuel.
Summary of the invention
The present invention provides a kind of spherical outside surface four-point contact ball bearing of usheing to seat for solving on the above technical problem, has solved extraneous foreign matter and has entered problems such as bearing and lubricant grease leak.
A kind of spherical outside surface four-point contact ball bearing of usheing to seat of the present invention comprises outer ring, inner ring, roller, seal ring, ball blocking block and taper pin; The outer ring is enclosed within on the inner ring, between outer ring and the inner ring roller is housed, and the space between outer ring and the inner ring is sealed by seal ring; Wherein, the side on the circumference of outer ring is offered cell body at the middle part, and ball blocking block is set in the cell body, and the outside neutral position of ball blocking block radially offers the tapped hole that is used to connect outside seat suspension hook.
The present invention's spherical outside surface four-point contact ball bearing of usheing to seat, its improvement is: upper axial direction in parallel described outer ring, cell body position is offered pin-and-hole in the outer ring; Offer the conical bore of corresponding outer ring pin-and-hole on the ball blocking block, in pin-and-hole and conical bore, taper pin is set, thereby ball blocking block is locked on the outer ring; Ball blocking block is provided with raceway near inner ring one side.
The present invention compared with prior art, the tapped hole that the outside of ball blocking block is radially offered can the connecting base suspension hook, can be convenient for assembly and maintenance, have the following advantages: significantly reduced friction, improved lubricating condition, improved lubricated quality, reduced frictional heating and energy loss, thereby improved bearing life greatly.
Description of drawings
Fig. 1 is the sectional structure chart of bearing of the present invention;
Embodiment
The present invention includes as seen from Figure 1, Figure 2: comprise outer ring 1, inner ring 2, roller 3, seal ring 4, ball blocking block 5 and taper pin 6; Outer ring 1 is enclosed within on the inner ring 2, between outer ring 1 and the inner ring 2 roller 3 is housed, and the space between outer ring 1 and the inner ring 2 is by seal ring 4 sealings; The outside of ball blocking block 5 radially offers tapped hole, and tapped hole 7 can the connecting base suspension hook.
The spherical outside surface four-point contact ball bearing of usheing to seat that with the diameter is 820mm is an example: the nominal width of outer ring is 56mm, and nominal bore diameter is 582mm; Ball blocking block thickness is 22mm, and surface roughness is 2.5, and the surface roughness of conical surface is 1.25, and the surface roughness of roller surface is 0.65.
In addition, inventive point of the present invention is the mounting type of roller, and wherein, the side on 1 circumference of outer ring is offered the cell body that is used to install roller at the middle part, after roller sets by cell body, utilizes ball blocking block 5 shutoff cell bodies, thereby limits the position of roller.In order to reach the shutoff lock function.The axial direction that is positioned at parallel outer ring, cell body position on outer ring 1 is offered pin-and-hole, and offers the conical bore of corresponding outer ring 1 pin-and-hole on the ball blocking block 5; Taper pin 6 is set in above-mentioned pin-and-hole and conical bore, thereby ball blocking block 5 is locked on the inner ring 1, and therefore lock roller.
Claims (2)
