Description
Technical field
The present invention relates to a kind of ball bearing that comprises outer ring, inner ring, a plurality of ball and retainer.In addition, the invention still further relates to self wind clock with swingle and ball bearing.
Background technique
The structure of self wind clock is before opened in flat 11-183645 number open at Ru Te.In this self wind clock, have following self wind structure, that is: its movement comprises ball bearing, is fixed in the rotation body of rod of ball bearing and is fixed in the rotation heavy burden of rotating the body of rod." movement " herein is meant the clockwork part that comprises drive part.In movement, when [glass side], [hornbook side], [dorsal part] are illustrated in movement assembled, a side of glass is arranged, a side of hornbook is promptly arranged with respect to base plate.In addition, in movement, after [front side], [bonnet side] are illustrated in and embed movement in the shell, with respect to a side of lid in the having of base plate.Contain that going barrel wheel, second is taken turns, anterior circular row, square hole wheel, first clamping plate and second clamping plate of third round, four-wheel etc., escapement, speed regulating mechanism, self wind mechanism etc. are configured in front side, i.e. the bonnet side of base plate.Rear portion circular row, calendar mechanism etc. are configured in the dorsal part of base plate.
In self wind mechanism, if swingle rotation, then the swingle tooth that is made as one with swingle also rotates.By the rotation of swingle tooth, the rotation of first handsetting wheel.By first handsetting wheel rotation, according to the eccentric motion of the eccentric axial portion of first handsetting wheel, pawl bar is done back and forth movement.Second handsetting wheel has ratchet.Pawl bar has pawls and pulling claw.Pawl and the ratchet engaged of pulling claw and second handsetting wheel.By pawling and the pulling claw back and forth movement, second handsetting wheel is rotated to a fixed-direction.By the rotation of second handsetting wheel, the rotation of square hole wheel, and the clockwork spring in the rolling-in going barrel wheel.
Referring to Fig. 6~Fig. 8, in the movement of self wind clock, the ball bearing portion of swingle is that ball bearing 962 has inner ring 968, keeps circle 970 and outside circle is outer ring 972.Keep circle 970 to be fixed on the inner ring 968.Therefore, inner ring 968 constitutes inboard circle with keeping circle 970.The inclined plane part that 5 balls 974 are assembled in inner ring 968 promptly in first side guide and the chamfered portion that keeps circle 970 promptly in second 2 chamfered portions of side guide and outer ring 972 be between the guided outside portion.Swingle tooth 972b is set in the peripheral part of outer ring 972.Retainer 976 is assembled in inner ring 968 and keeps between the circle 970 to dispose a plurality of balls 974 with interval.Retainer 976 adopts sheet metals such as stainless steel, by the punch process to sheet metal, forms its outer shape.On retainer 976, be provided with 5 semicircular ball positioning part 976g that determine ball 974 positions.Around each ball 974, inject lubricant oil.
The ball bearing that is used for the movement of traditional self wind clock has the structure that comprises outer ring, inner ring (containing the maintenance circle that is fixed in inner ring), a plurality of ball and retainer.Contact between these parts (promptly sliding) state is divided into [contact of rolling] and [sliding contact].That is: contacting between outer ring and the ball is [contact of rolling].Contacting between inner ring (and keep circle) and the ball is [sliding contact].Contacting between retainer and the ball is [sliding contact].If [contact of rolling] and [sliding contact] made comparisons, then generally known [sliding contact] wears no resistance than [contact of rolling].Therefore, for ball bearing before, many life-spans of determining ball bearing according to the wearing and tearing progress of retainer.For reducing this wearing and tearing on the retainer, on ball, inject lubricant oil, then following problem can take place.
The first, vibration, impact when using owing to ball bearing have the possibility that causes lubricant oil to disperse.Its result, lubricant oil is attached to does not need the place of lubricant oil, thereby causes the deterioration of various part performances.For example, lubricant oil sticks together on the flank of tooth of gear, will increase the viscosity loss of circular row structure.In addition, when lubricant oil sticks together on hairspring, can cause the clock accuracy disorder.
The second, owing to varying with temperature, oil body becomes, can cause the decline of various characteristics.For example, under low-temperature condition, oil body increases, and starting torque is increased, and can cause responding variation like this.In addition, under the condition of high temperature, the oil body reduction, can making perhaps, the appearance load reduces and takes place to flow oily.
