Abstract

An anti-shock assembly for a mobile component that turns about its axis consists of at least one spring component (1, 1') with a series of radial vanes between its outer edge (5) and a central support (3) that holds the axle of the mobile component or a stone (2). The anti-shock assembly for a mobile component that turns about its axis consists of at least one spring component (1, 1') with a series of radial vanes between its outer edge (5) and a central support (3) that holds the axle of the mobile component or a stone (2). The vanes can be inclined so they form an angle of 0 - 15 degrees with the diameter of the component, and they can be curved in shape. Each spring component can be made from metal, plastic or both by traditional machining, electro-erosion, electroforming, stamping, micro-moulding by illuminating resins that are sensitive to UV radiation, or by galvanic deposition or treatment.

Description

The damping device of the moving object of on trunnion shaft, rotating

Technical field

The invention belongs to the clock and watch technology, the damping device of the moving object of particularly on trunnion shaft, rotating.

Background technique

Usually the transmission damping device of using in the clock and watch technology has five parts: jewel hole, arch bar, jewel bearing radially, thrust jewel bearing and spring.Spring-loaded is on the thrust jewel bearing.When above-mentioned five element sets are in jewel hole, this moment the spring size little and work in amplitude less.Damping device of Gou Chenging thereby effect are limited like this.In addition, be the device of a relative complex at moving object said elements up and down, this device must decompose fully in the time will changing an element.

The patent of invention content

The objective of the invention is to eliminate these shortcomings.

Of the present invention to liking the damping device of the moving object of on trunnion shaft, rotating.

Damping device according to moving object of on trunnion shaft, rotating of the present invention, it is characterized in that, it comprises the elastic member that at least one is made up of a series of blades, and the periphery that these blades connect these parts couples together with the central jewel hole of the trunnion shaft of preparing the support motion object.

Blade can be radially and towards the device the center.

Blade also can be oblique, becomes 0-15 ° of acute angle with the diameter of device.

Blade also can curved shape.At this moment circular arc be will take and the periphery and the central jewel hole of elastic member connected.

In a preferred embodiment, the engage grooves of blade and jewel hole inner periphery.Gapped between blade and the groove.

The jewel that is used for support motion object trunnion shaft compels to be incorporated in the jewel hole.

This device generally includes the elastic member of two around the movement objects, and they can be escapement and hairspring combination, and at this moment the stud seat of jewel hole and escapement forms one.

Elastic member can have a clear area, on it without any spring sheet.

Another purpose of the present invention is the production method of this device, it is characterized in that, it comprises traditional machining, line cutting (wire electro discharge machining), spark-erosion sinking (electric discharge machining), Punching Technology, the micro-forming technique that the exposure of UV photosensitive resin is finished, the electro-deposition of minisize mould or the plating of substrate, this installs available full genus or plastics, or uses two kinds of material simultaneously.

Fig. 5 is the A detailed drawing among Fig. 4,

Fig. 6 is mounted in the escapement of damping device inboard of suspension and the perspective view of hairspring combination, the upper part of this device by brachymemma so that show the regulating system of escapement.

Fig. 7 is the top view of a variant of the device among Fig. 6, and

Fig. 8 is the sectional drawing of the device among Fig. 6, and the potential use that provides of said apparatus is shown.

Embodiment

Elastic member shown in Fig. 1-5 comprises the jewel bearing of compeling to be incorporated in the jewel hole 2, and bearing hole itself is by a series of blade 4 supportings, and each blade radially stretches to center 3 by the annulus 5 of parts 1, and parts 1 are disk-shaped.

In illustrated embodiment, blade radially stretches to the parts center, but according to a variant that does not show, blade 4 can be crooked or tilts, and with the angle of parts diameter be 0-15 ° of acute angle, but as shown in Figure 2, blade 4 is along attenuation 2/3 on the length at the center of sensing.

4 cushioning effects of spring sheet, as shown in Figure 3, guiding is installed with the jewel bearing 2 of the motion of mechanism object of elastic member, compels to be incorporated in the jewel hole 3 by friction.

The down suction of moving object can by being pressed into jewel bearing 2 how much being adjusted in the jewel hole 3, and the periphery of jewel hole 3 has a groove 6, is used for fixing blade 4.

The location of spring sheet 4 can illustrate that jewel hole 3 must be adjacent to and force in above-mentioned blade 4 fully and cross jewel hole 3 until them with blade 4, and is placed in the groove 6 referring to Fig. 4.When blade is located in groove 6, spring sheet 4 is just got back to the home position, and parts 1 are also got back to its flat pattern, Fig. 5 illustrates the detailed drawing of the section A of jewel hole 3, wherein contained blade 4 has been returned to its smooth state of rest, and Fig. 5 also is illustrated between groove 6 and the above-mentioned blade vertical gap 7.Equally, between the bottom surface of above-mentioned blade 4 and groove 6, less lateral clearance 8 is arranged.

Gap

7 and 8 makes the parts 1 can be free movable and be in the optimum state.

Parts 1 can be with known the whole bag of tricks manufacturing at present, and as traditional machining, line cuts (wire electro discharge machining), electrical forming (electric discharge machining), Punching Technology, the micro-forming technique that UV photosensitive resin exposure produces, the electro-deposition of minisize mould or the plating of substrate when not having minisize mould.

The material of parts is made by plastics or metallic material, or makes with two kinds of materials simultaneously, also can make with Electricinjection or electro-deposition in minisize mould.

Fig. 6 illustrate two

elastic members

1 and 1 of being installed in Fig. 1-5 ' between escapement and the damping device of hairspring combination 9, if escapement and hairspring combination 9 are by installation shown in Figure 6, then the outer column base 10 of can regulate escapement 9 is major components of jewel hole 3, and can utilize the slit 11 in the upper part of jewel hole 3 to adjust.

As a kind of modification, for device is done accurate adjustment, parts 1 or 1 ' a part can flow out blank, for shown in Figure 7, help adjusting near outer column base 10 than being easier to like this.

In the use, but the much bigger amplitude of device absorptance prior art damping device of Fig. 6, and escapement parts thereby better protected in addition, are that replaceable escapement makes up with hairspring in device, need not decomposing unit.

As shown in Figure 8, but tool using extracts spring sheet 4 along arrow 12 directions, can pull down escapement and hairspring combination 9 when taking off spring sheet, and another escapement is put in the device, need not the decomposition and combination part.

Although develop damping device for clock and watch, its purposes is not limited to this field, and said apparatus also can be applicable to a lot of technical fields, as machinery, micromechanics, aerospace industry etc.
