Description
The utility model TV remote Antenna change direction device belongs to the antenna transfer, relates to a kind of steering gear of telecontrol antenna.
The multi-stage gear speed change is often adopted in the steering gear of telecontrol antenna in prior art, and the speed change level is three, more than the level Four, complex structure, stuck easily, profile of tooth point is little and tooth is close, easily produces climbing tooth and beats the tooth phenomenon, and wind loading rating is poor, more than the speed change level and transmission efficiency is low, poor reliability, use installation and maintenance inconvenience, result of use is poor, and the life-span is short, the cost height, energy consumption is big.
The purpose of the utility model TV remote Antenna change direction device, it is the deficiency that overcomes prior art, a kind ofly make steering gear drive television antenna at the in-house operation remote control panel to rotate and relate to, stable drive, simple in structure, safe and reliable, the speed ratio height, excellent in efficiency, easy to use, rotate TV remote Antenna change direction device flexibly.
The utility model TV remote Antenna change direction device takes following scheme to realize: adopt the K-H-V Gear Planet Transmission, output speed speed change with motor, it is by motor, duplicate gear and sun gear, the reducing gear that output gear is formed, shell three parts constitute, power shaft on the motor is fixed with eccentric adjusting sleeve, outer device has duplicate gear, and sun gear maintains static, and connects together with motor and shell, the output gear device is between duplicate gear and shell, and and sun gear constitute engagement together to duplicate gear, what cooperates arrangement with the axis hole of output gear is output shaft, output shaft and power shaft are concentrics.Duplicate gear and sun gear and output gear constitute reducing gear.Sun gear and motor and shell are fixed together.A gear during work in the duplicate gear with sun gear engagement rotation process in do reverse low speed rotation simultaneously, drive output gear under the effect of another gear in duplicate gear and rotate, make the output shaft low-speed running.By installing locator card on the output shaft, device two pawls and lead constitute on the two pawl spring seats.
The effect of the utility model TV remote Antenna change direction device is: simple and reasonable, and stable drive, safe and reliable, ratio coverage is wide, the efficient height, easy to use, noise is low, the intensity height, and the life-span is long, and volume is little, wind loading rating is strong, and cost is low, rotates flexibly the positive and reverse return three-sixth turn.
The utility model TV remote Antenna change direction device will be further described in conjunction with the accompanying drawings.

With reference to Fig. 1,2, the reducing gear of the utility model TV remote Antenna change direction device is by duplicate gear (1) and duplicate gear (2), sun gear (3) and output gear (4) constitute, duplicate gear (1) and duplicate gear (2) are on one, sun gear (3) maintains static, be connected with shell (6) with motor (5), the power shaft (7) of motor (5) is gone up fixedly eccentric adjusting sleeve (8), matches with the axis hole of sleeve (9) and duplicate gear (1), (2).Output gear (4) device is between duplicate gear (1), (2) and shell (6), and constitute the engagement of duplicate gear (1), (2) with sun gear (3), sun gear (3) and duplicate gear (1), the number of teeth differs 1 tooth to multiple tooth between output gear (4) and the duplicate gear (2).Power shaft (7) and output shaft (10) are concentrics.During work, because the special role of eccentric adjusting sleeve (8), duplicate gear (1) meshes in the rotation process with sun gear (3), do reverse low speed rotation simultaneously, duplicate gear (2) drives output shaft (10) and rotates, make output shaft (10) low speed rotation, positive and reverse return transfers 360 degree to, goes up device two pawl springs (12) by output shaft (10) with locator card (11) and two pawl spring seats (13) and is constituted with lead (14).
The embodiment of the utility model TV remote Antenna change direction device: be that sun gear (3) adopts 29 needle-like teeth, duplicate gear (1) is 28 teeth, mesh with sun gear (3) inscribe, duplicate gear (2) is 27 teeth, with output gear (4) inscribe engagement mutually, the meshing point of duplicate gear (1), (2) and sun gear (3) and output gear (4) is in the same side.Output gear (4) is 28 teeth, sun gear (3) is 1 with the lower teeth difference of tangent duplicate gear (1), when power shaft (7) rotates a week, eccentric adjusting sleeve (8) drives duplicate gear (1) public affairs and circles, and in the opposite direction relative rotation one tooth of duplicate gear (1), thereby obtain slowing down.When duplicate gear (2) relatively rotated 27 circles, output gear (4) rotated a tooth, thereby obtained low output, and transmission speed ratio is 27 * 28:1.During use, cooperate, can do positive and negative 360 degree rotations, make reception the best of television antenna with remote control panel.Motor adopts miniature.Micromotor output shaft (10) is gone up device locator card (11), goes up device two pawl springs (12) and lead (14) at two pawl spring seats (13), and when locator card (11) rotated collision two pawl springs (12), its loop conducting was reversed.Two pawl springs (12) a, b are respectively two pawls, device 6v direct voltage between 2, and polarity is variable, when importing forward 6v direct current between C, D, presses 2A, D
1Because of bearing forward voltage conducting, D
2End because of bearing reverse voltage, the conducting of CADC loop, locator card (11) on the motor drives output shaft (10) is rotated in the forward, when locator card (11) forwards a week to, locator card (11) forces a pawl to separate with the A point, whole loop open circuit, locator card (11) stops operating, and finishes the rotation of forward 360 degree.The polarity of power supply is exchanged between C, D, presses 2A, CADC loop open circuit, D
2Because of bearing the forward voltage conducting, the conducting of DBCD loop, locator card (11) begins counter-rotating under the drive of DC motor.When locator card (11) when turning an angle, though a pawl is connected its D with the A point
1What bear is reverse voltage, and the DACD loop still is in off state.When locator card (11) was inverted to a week, locator card (11) forced the b pawl to separate with the B point, and entire circuit is in off state, has finished the function of contrary three-sixth turn.Thereby finished the rotation control of positive and negative 360 degree of whole device, controlled the rotation of whole device optional position in positive and negative 360 degree by switch 2A.
