Abstract
The utility model discloses a Tourbillon support mechanism, comprising a second gear component, a second lower clamping plate component, a second gear shaft, a lower antifriction bearing, an upper antifriction bearing, a second gear sheet and a Tourbillon support, wherein the Tourbillon support is connected with the second gear shaft, the second gear component is engaged with the second gear shaft, the second gear shaft passes through the upper antifriction bearing fixed on the second gear sheet and the lower antifriction bearing pressed on the second lower clamping plate component. The Tourbillon support mechanism has the beneficial effects that the upper and lower ends of the second gear shaft are respectively matched with the antifriction bearings, thereby better correcting the influence on time precision, from the friction torque of a Tourbillon in the process of passing through a vertical plane, and ensuring the stability and accuracy of a watch located in a vertical plane; and the double-bearing type Tourbillon support mechanism is suitable to cantilever type, bridge type and special type Tourbillon mechanisms, and the utility model is also suitable to any Tourbillon support mechanism.
Description
Technical field
The utility model relates to a kind of top flywheel supporting device of mechanical watch; Particularly relate to a kind of center impeller type top flywheel-bracket mechanism.
Background technology
Tourbillion mechanical watch is a kind of complicated technology mechanical timing instrument with the rotation speed adjusting gear.The timekeeping performance of good degree direct influence wrist-watch in the facade process to the speed adjusting gear supporting.The supporting device that in the past the rotation speed adjusting gear was used mostly is the mixing bearing of jewel or jewel and bearing.For example, publication number is the patent of CN201060380Y, and wherein, the top flywheel-bracket is a kind of mixing bearing mechanism, and the advantage of this supporting device is that calibration presents sinusoidal curve in the time of can improving to a certain extent the walking of wrist-watch facade; Shortcoming is to improve fully that friction force namely affects timekeeping performance to the impact of second pinion in the facade process.
Summary of the invention
The utility model technical issues that need to address are, provide a kind of friction force steady, and are lower on the impact of wrist-watch timekeeping performance, and the duplex-bearing type top flywheel-bracket mechanism of reliable operation.
The technical scheme that the utility model adopts is: a kind of top flywheel-bracket mechanism comprises second hand wheel component, second lower plate parts, second pinion, lower rolling bearing, upper rolling bearing, second wheel sheet and top flywheel-bracket; Described top flywheel-bracket is connected with second pinion; The upper rolling bearing that is fixed on the second wheel sheet and the lower rolling bearing that is pressed together on second lower plate parts are passed in described second hand wheel component and second pinion engagement, described second pinion.
The upper end of described second pinion embeds a second upper tooth axle sleeve, and the bottom of described second pinion embeds a second lower tooth axle sleeve; Described second is tooth axle sleeve and upper rolling bearing interference fit upward, described upper rolling bearing and second wheel sheet interference fit; Described second lower tooth axle sleeve and lower rolling bearing interference fit, lower rolling bearing is pressed together on second lower plate parts.
Described second, upper tooth axle sleeve and top flywheel-bracket were in the same place with screw fastening by the clamping plate post; The upper end of described second pinion and a second upper tooth axle sleeve interference fit.
The beneficial effects of the utility model are: because the upper and lower side of second pinion cooperates with rolling bearing respectively, can proofread and correct preferably the moment of friction of top flywheel in the facade process to the impact of timekeeping performance, thus stability and accuracy when having guaranteed that wrist-watch is walked when facade; This duplex-bearing type top flywheel-bracket mechanism is not only applicable to cantilevered, bridge-type and spatial top flywheel mechanism, more applicable in any top flywheel-bracket structure.

1: second hand wheel component 2: second lower plate parts
3: second pinion 4: second lower tooth axle sleeve
5: lower rolling bearing 6: upper rolling bearing
7: second wheel sheet 8: top flywheel-bracket 9: tooth axle sleeve on second.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done further and to be elaborated.
As shown in Figure 1, the utility model top flywheel-bracket mechanism comprises, second hand wheel component 1, second lower plate parts 2, second pinion 3, second lower tooth axle sleeve 4, lower rolling bearing 5, upper rolling bearing 6, second wheel sheet 7, top flywheel-bracket 8 and second upper tooth axle sleeve 9; Upper tooth axle sleeve 9 was in the same place with screw fastening by the clamping plate post with top flywheel-bracket 8 in described second; Described second hand wheel component 1 and second pinion 3 engagements, described second pinion 3 passes the upper rolling bearing 6 that is fixed on the second wheel sheet 7 and the lower rolling bearing 5 that is pressed together on second lower plate parts 2, wherein, the upper end of described second pinion 3 and second upper tooth axle sleeve 9 interference fit, the bottom of described second pinion 3 embeds a second lower tooth axle sleeve 4; Described second is tooth axle sleeve 9 and upper rolling bearing 6 interference fit upward, described upper rolling bearing 6 and second wheel sheet 7 interference fit; Described second lower tooth axle sleeve 4 and lower rolling bearing 5 interference fit, lower rolling bearing 5 is pressed together on second lower plate parts 2.
Principle of work of the present utility model is: the top flywheel-bracket is by upper rolling bearing and lower roller bearings, and during the wrist-watch operation, second hand wheel component drives the second pinion rotation, second pinion so that drive second upper tooth axle sleeve with top flywheel-bracket rotation that second, upper tooth axle sleeve was connected.Particularly when facade is walked in the process, the weight of this structure concentrates on top flywheel-bracket part, and upper rolling bearing place is owing to the weight of whole mechanism is subject to a downward pressure, and this is subject to an acting force that makes progress in rolling bearing place at present.So the rolling bearing on second pinion top supporting situation can only offset because the downward pressure that the deadweight of whole mechanism produces.And make whole mechanism be in the supporting structure that equilibrium state is the second pinion bottom.The bottom uses the rolling bearing key to be to offset moment of friction to the impact of timekeeping performance.In addition, this structure can prolong the serviceable life of second pinion.
