Abstract
The utility model discloses a new pattern of steel ball friction pair, in particular to a plane rolling friction device, which is applicable to a plurality of plane sliding friction mechanisms. A bearer (1) is welded on the upper middle part of a lower basal disc (13). A lock nut (11) and an adjustable turnbuckle (2) are movably connected with the upper end of the bearer (1). A steel ball bush (3) is arranged on the upper end of the adjustable turnbuckle (2). An isolation frame (9), a central steel ball (8) and a steel ball (12) are mounted at the internal end of the steel ball bush (3), and a friction disc (7), which is movably installed on the central steel ball (8) and the steel ball (12), are movably connected with an upper basal disc (6). For having a rolling plane sliding friction pair and a vernier unit, the utility model is provided with the advantages of the plane sliding friction and the rolling friction and overcomes the disadvantages of the two friction modes. Moreover, with small frictional coefficient and greatly reduced unavailable power of the machine parts consumed by the friction, the utility model is an ideal substitute of the plane rolling friction pair and plane ball bearing and can be used in a kinematical mechanism with multiple purposes.
Description
Technical field:
The utility model relates to a kind of new steel ball friction pair, specifically is meant to be fit to the plane rolling rubbing device that multiple planar slide friction mechanism uses.
Background technique:
Extensively be used at present the single steel ball rolling friction pair in planar linkage and the rocker arm body.The single-point area of contact is little, bear that pressure is big, frictional force is big, abrasion is serious, and causes a very dark wearing and tearing annular groove, and motion is not steady.Especially show on fertilizer urea sieve and other screening plant that often break down, easily damaged parts is changed frequent.
The model utility content: the utility model has changed the defective of former single steel ball rolling friction pair, provide a kind of with planar slide friction and rolling friction, unite two into one, be applicable to the linkage mechanism and the rocker arm body of multiple pattern, replace the plane rolling rubbing device of plane rolling bearing.Its supporting base 1 is welded on middle part on the low bottom-disc 13, locking nut 11 and adjustable swivel nut 2 are movably connected in supporting base 1 upper end, steel ball watt 3 devices are in adjustable swivel nut 2 upper ends, isolating frame 9 and central steel ball 8, steel ball 12 devices are inner on steel ball watts 3, rub dish 7 heads on central steel ball 8, steel ball 12, and and top bottom-disc 6 flexible connections.The utility model is in a plane bearing shell, establishes a steel ball, makes the central locating point, and around placing with six equal diameter steel balls, seven planes that steel ball is formed contact with last friction disk, form a rolling planar slide friction pair.And have vernier device, to keep steel ball and friction disk appropriate gap.Be characterized in having the advantage of planar slide friction and rolling friction, overcome both shortcomings again, friction factor is little, and frictional force is little, reduces the useless power that parts consume because of friction greatly.The ideal that is current planar slide friction pair and plane ball bearing replaces device.This device is added with other constitutional detail, becomes the integral body of a sealing, can be used in the multi-purpose motion.
Description of drawings:
Fig. 1 is a main sectional view of the present utility model
Fig. 2 is the plan view of Fig. 1
Embodiment:
Shown in Figure 2 as Fig. 1, the technical solution of the utility model is finished as follows: the dish that rubs has seven steel balls, also can make friction pair with seven, five, four steel balls or above the same principle of seven steel ball structures, central authorities' steel ball 8, play the centralized positioning effect, six equal diameter steel balls 12 are set on a disk around central steel ball 8.Seven steel balls have an isolating frame 9, and steel ball is separated, and run foul of each other in order to guarantee that each steel ball does not produce, and keep its original position, make steel ball form a horizontal rubbing surface, fill lubricating grease in watt, keep the good lubrication between steel ball and the friction disk.Central authorities' steel ball 8 and six equal diameter steel balls 12 are installed in the steel ball watts 3, which is provided with a friction disk 7, in order to support motion spare.Rubber protecting jacket 4 is by packing ring 5 and bolt 10; be fixed on top bottom-disc 6 and the low bottom-disc 13; top bottom-disc 6 heads are on steel ball watts 3; and and low bottom-disc 13 links together; form a complete plane rolling rubbing device; and being in whole sealing status, the dish lubricating grease that prevents to rub is by extraneous contamination by dust.Supporting base 1 is welded on the low bottom-disc 13 middle part, and locking nut 11 and adjustable swivel nut 2 are movably connected in supporting base 1 upper end, and steel ball watt 3 devices are in adjustable swivel nut 2 upper ends, main bearing friction dish pressure; In order to adjust the gap between supporting base and steel ball and the friction disk; Coil and the steel ball gap to keep rubbing, and after abrasion, do the compensation adjustment effect.
When using certain linkage mechanism or rocker arm body, fulcrum is positioned on the dish that rubs, this moment, support pressure was distributed on seven steel balls, when the friction disk upper supporting part was done plane motion, seven steel balls rolled in the original place, and planar friction is converted to rolling friction, and in the plane rolling circle, form a rolling friction plane, significantly reduced friction factor and frictional force, saved the useless power of whole movement parts consumption in friction.Whole device is a seal, is applicable to the linkage mechanism and the rocker arm body of various ways, can install and use on any parts.
Claims (3)
1. plane rolling rubbing device, it is characterized in that supporting base (1) is welded on low bottom-disc (13) and goes up the middle part, locking nut (11) and adjustable swivel nut (2) are movably connected in supporting base (1) upper end, steel ball watt (3) device is in adjustable swivel nut (2) upper end, isolating frame (9) and central steel ball (8), steel ball (12) device are gone up inner at steel ball watt (3), rub dish (7) head on central steel ball (8), steel ball (12), and and top bottom-disc (6) flexible connection.
