Abstract
The unity model provides a clock and watch friction minute pinion structure, which comprises a cannon sheet and a cannon pinion, the wall of the cannon sheet center hole interference co-operate with the mating surface of the cannon pinion as a radial working plane. The model is characterized in that more than one radial elastic paw are arranged on the cannon sheet, and the end of the elastic paw is provided with a spherical protuberance, saddle-backing quantity exists at the end of the spherical protuberance relatively to the lower of the cannon sheet, the spherical protuberance knocks at the friction face contacting with the cannon sheet on the cannon pinion. The unity model develops the axial pressure by the interference co-operating of the elastic paw between the cannon sheet and the cannon pinion and the located friction plane, forms the important part for the frictional couple on the cannon part, and improves the stability of the cannon couple.
Description
Technical field
The utility model relates to a kind of clock and watch friction and divides wheel construction.
Background technology
The control clock and watch divide the wheel component moment of friction and improve its stable importance and degree of difficulty is that the professional and technical personnel is in common knowledge, we can say that it is the common difficulty that coremaking manufacturing plant faces.In order to reduce cost, the minute wheel friction structure is tending towards oversimplifying and cost degradation, and the tolerance of plastic injection piece is subjected to injecting condition, and the influence of environmental baseline and timeliness is fairly obvious again, makes the control of moment of friction difficult more.
Concrete minute wheel friction mechanism has multiple, but all relies on the elasticity muscle on the minute wheel and the resilient engagement of cannon pinion basically, and the magnitude of interference that relies on both axis holes to cooperate is controlled the size of moment of friction.
Summary of the invention
The utility model fundamental purpose provides a kind of new design that improves clock and watch friction branch wheel construction moment of friction stability, thereby improves the total quality of movement.
A kind of clock and watch friction divides wheel construction, comprise minute wheel sheet and cannon pinion, the wall of minute wheel sheet center pit is as the mating surface interference fit of workplace and cannon pinion radially, it is characterized in that: also be provided with one or more radial elastic pawl on the minute wheel sheet, the end of elastic claw is provided with ball bumps, the end of ball bumps has projection amount with respect to the lower surface of minute wheel sheet, the bulbous protrusion contact on the cannon pinion with the contacted rubbing surface of minute wheel sheet on.
The mating surface of described cannon pinion has tapering.
Elastic claw can be made as 3,2 or 4, evenly distributes along minute wheel sheet center pit circumference.
A kind of clock and watch friction divides wheel construction, comprise minute wheel sheet and cannon pinion, the wall of minute wheel sheet center pit is as the mating surface interference fit of workplace and cannon pinion radially, it is characterized in that: cannon pinion is provided with radially more than one or the circumferencial direction elastic claw, the end of elastic claw is provided with ball bumps, and the ball bumps contact is on the minute wheel sheet.
The essence of above-mentioned two kinds of schemes all is to utilize the interference fit of the rubbing surface of the elastic claw that adopts between minute wheel sheet and the cannon pinion and setting to produce axle pressure, forms a pith that divides the wheel component moment of friction, thereby has improved the stability of minute wheel moment.
