Abstract
The utility model relates to a transmission device of a thermometer, which comprises a mounting frame, a driving shaft and a pointer rotating shaft, wherein the pointer rotating shaft is longitudinally mounted on the mounting frame, the driving shaft is transversely mounted on the mounting frame, a driving gear is arranged on the driving shaft, a driven gear is arranged on the pointer rotating shaft, and the driving gear is meshed with the driven gear. The transmission device adopts the gear transmission and can ensure the flexible transmission, so that the transmission device has the advantages of simple structure, small occupied space, reduced volume of the thermometer and oil liquid conservation.
Description
(1) technical field
The utility model relates to a kind of thermometer, relates in particular to a kind of gearing of thermometer.
(2) background technology
The gearing of existing thermometer, comprise pointer shaft, driving shaft and mounting bracket, described pointer shaft longitudinally is housed on the described mounting bracket, on the head of described pointer shaft pointer is housed, its afterbody is connected with an end of a Flexible Rotating, the other end of Flexible Rotating is connected with driving shaft, and described Flexible Rotating is the bending Flexible Rotating, and described driving shaft is connected with the temperature-sensitive web member.In use, the temperature-sensitive web member is subjected to Temperature Influence to make drive shaft turns, and driving shaft orders about the Flexible Rotating rotation then, rotates thereby drive pointer shaft, and the pointer on the pointer shaft can indicate the dut temperature value on the scale dish.There is following shortcoming in this gearing: drive the pointer shaft rotation owing to adopt Flexible Rotating to rotate, this Flexible Rotating makes the structure of this gearing take up room greatly for what bend, thereby makes the volume of whole thermometer become big.Because be full of oils liquid in the thermometer, thereby increase is to the use amount of oils liquid.Simultaneously, if pointer shaft is rotated, need overcome the elastic force of Flexible Rotating, Flexible Rotating was used of a specified duration, rotated dumbly easily, influenced the degree of accuracy of thermometer indicating value.
(3) summary of the invention
Have above-mentioned deficiency in the prior art in order to overcome, the utility model provides a kind of degree of accuracy height of simple in structure, thermometer indicating value, the gearing of thermometer easy to use.
The technical scheme in the invention for solving the technical problem is: a kind of gearing of thermometer, comprise mounting bracket, driving shaft and pointer shaft, described pointer shaft longitudinally is loaded on the described mounting bracket, described driving shaft laterally is equipped with on the edge on the described mounting bracket, described driving shaft is provided with a driving gear, described pointer shaft is provided with a follower gear, described driving gear and described follower gear engaged transmission.
As further improvement of the utility model, be installed with a round hairspring on the described pointer shaft, the end, outer ring of described round hairspring is fixed on the described mounting bracket.Described round hairspring can make the pointer stability of rotation, guarantees the degree of accuracy of thermometer indicating value.
As further improvement of the utility model, described mounting bracket is by erection support and place the support plate of described erection support top to form, be connected by pillar between described support plate and the erection support, the bottom of described erection support extension downwards is provided with an erecting frame, described driving shaft laterally is equipped with on the edge on the described erecting frame, described pointer shaft longitudinally is housed between described support plate and the erection support, and the end, outer ring of described round hairspring is fixed on the described pillar.
The utility model in use, described driving shaft is connected with the temperature-sensitive web member, described pointer shaft is connected with pointer, when temperature changes, the temperature-sensitive web member is subjected to Temperature Influence to make drive shaft turns, thereby the follower gear that the driving gear on the driving shaft drives on the pointer shaft rotates, and then the pointer on the pointer shaft also rotates, thereby indicates correct temperature value.In the gear-driven process, between the teeth of driving gear and follower gear certain interval is arranged, in gear operation, the moment of reaction of the round hairspring on the pointer shaft, single-phase contact the when making gear pair guarantee in motion process that driving gear meshes with follower gear, make the pointer running steadily, can guarantee the degree of accuracy of thermometer indicating value.
The beneficial effects of the utility model are: the utility model adopts gear drive, can guarantee ensuring smooth transmission, make transmission structures simple, it is little to take up room, dwindle the volume of thermometer, simultaneously the round hairspring on the pointer shaft can be so that degree of accuracy height reliable and stable during the utility model work, the thermometer indicating value.
(4) description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, the gearing of a kind of thermometer of Fig. 2, comprise mounting bracket 1, driving shaft 2 and pointer shaft 3, described pointer shaft 3 longitudinally is loaded on the described mounting bracket 1, described driving shaft 2 laterally is equipped with on the edge on the described mounting bracket 1, described driving shaft 2 is provided with a driving gear 4, and described pointer shaft 3 is provided with a follower gear 5, described driving gear 4 and described follower gear 5 engaged transmission.Described mounting bracket 1 is by erection support and place the support plate of described erection support top to form, be connected by pillar between described support plate and the erection support, the bottom of described erection support extension downwards is provided with an erecting frame, described driving shaft 2 laterally is equipped with on the edge on the described erecting frame, described pointer shaft 3 longitudinally is housed between described support plate and the erection support, be installed with a round hairspring 6 on the described pointer shaft 3, the end, outer ring of described round hairspring 6 is fixed on the described pillar.
The utility model in use, described driving shaft 2 is connected with the temperature-sensitive web member, described pointer shaft 3 is connected with pointer, when temperature changes, the temperature-sensitive web member is subjected to Temperature Influence to make driving shaft 2 rotate, thereby the follower gear 5 that the driving gear on the driving shaft 24 drives on the pointer shaft 3 rotates, and then the pointer on the pointer shaft 3 also rotates, thereby indicates correct temperature value.In the gear-driven process, between the teeth of driving gear 4 and follower gear 5 certain interval is arranged, in gear operation, the moment of reaction of the round hairspring 6 on the pointer shaft 3, single-phase contact the when making gear pair in motion process, guarantee driving gear 4 with follower gear 5 engagements, make the pointer running steadily, can guarantee the degree of accuracy of thermometer indicating value.
