Description
Technical field
The utility model relates to a kind of speed reducer, especially relates to a kind of worm reduction gear and joins servo without key bindiny mechanism.
Background technique
Speed reducer is a kind of power transmission mechanism, utilizes the velocity transducer of gear, the winding number of motor (motor) is decelerated to desired winding number, and obtains the mechanism of larger torque.Current in the mechanism of transferring power and motion, the application area of speed reducer is quite extensive.Its trace almost can be seen in the transmission system of various machinery, from boats and ships, automobile, the locomotive of the traffic tool, heavy machinery for building, the machining machine and tool that mechanical industry is used and automated production equipment, household electrical appliances common in daily life, clock and watch etc.Chinese patent discloses a kind of shock resistance gear reduction unit (Authorization Notice No.: CN 203272734 U), it comprises housing, housing is provided with input gear unit and output gear, input gear unit is connected by gear teeth wheels with between output gear, gear teeth wheels comprise first-level variable-speed gear, the transmission shaft being provided with two stage speed change gear and the three-stage speed change gear be connected with output gear, first-level variable-speed gear is arranged on the power intake of transmission shaft and is connected with input gear unit, two stage speed change gear is arranged on the clutch end of transmission shaft and engages with three-stage speed change gear, the inner chamber of housing is provided with the supporting station for installing transmission shaft, transmission shaft is arranged on supporting station by bearing, the inner chamber of supporting station is provided with the axially locating step matched with bearing, supporting station is located at the bottom of housing cavity, and bearing is dark roller bearing, and two stage speed change gear and three-stage speed change gear are bevel gear, and the power that input gear unit comprises for being connected with extraneous motor inputs land.But this speed reducer can only be connected with drive units such as motors by keyway, and be not therefore suitable for some actuating motors, Applicable scope is narrower, and the noise produced when servo motor transmission is larger.
Model utility content
The utility model is to provide a kind of worm reduction gear and joins servo without key bindiny mechanism, its speed reducer mainly solved existing for prior art can only be connected with drive units such as motors by keyway, therefore some actuating motors are not suitable for, Applicable scope is narrower, and the technical problem of the larger grade of the noise produced when servo motor transmission.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Worm reduction gear of the present utility model joins servo without key bindiny mechanism, comprise casing, worm gear is provided with in described casing, worm gear is engaged with worm screw, casing is fixed with servo flange, and worm screw one end extend in servo flange, the casing at worm screw the other end place is provided with oil seal cover, worm end is provided with connecting ring, and connecting ring has groove, and on groove, cross-under has adjustment screw.Arrange connecting ring in the end of worm screw, and offer groove, the internal diameter of connecting ring can be made adjustable, and it can connect the component such as the output shaft of actuating motor, then by adjustment screw lock.
As preferably, between described worm screw and casing, be provided with bearing.Worm screw can be made more smooth and easy rotatably by bearing.
As preferably, between described servo flange and worm end, be provided with oil sealing.Oil sealing can prevent the fluid in casing from leaking.
As preferably, the madial wall of described casing is provided with zigzag caulking groove, and caulking groove is embedded with acoustical cotton.Caulking groove itself, owing to being zigzag fashion, can absorb the more noise that clutch produces, and acoustical cotton is inlaid on caulking groove relatively more firm, and acoustical cotton can absorb noise better.
Therefore, the utility model connects servo flange on casing, and arranges the adjustable connecting ring of internal diameter in the end of worm screw, makes it connect actuating motor, and Applicable scope is comparatively wide, and the noise produced is also less, simple and reasonable for structure.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is a kind of structural representations of the utility model connecting ring.
Component, position and numbering in figure: casing 1, worm gear 2, worm screw 3, servo flange 4, oil seal cover 5, connecting ring 6, groove 7, adjustment screw 8, bearing 9, oil sealing 10, caulking groove 11, acoustical cotton 12.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the worm reduction gear of this example joins servo without key bindiny mechanism, as Fig. 1, comprise casing 1, in casing, be provided with worm gear 2, worm gear is engaged with worm screw 3, casing is fixed with servo flange 4, worm screw one end extend in servo flange, and the casing at worm screw the other end place is provided with oil seal cover 5, worm end is provided with connecting ring 6, as Fig. 2, connecting ring has groove 7, on groove, cross-under has adjustment screw 8.Bearing 9 is provided with between worm screw and casing.Oil sealing 10 is provided with between servo flange and worm end.The madial wall of casing is provided with zigzag caulking groove 11, caulking groove is embedded with acoustical cotton 12.
During use, worm screw 3 is connected the actuating motor of upper driving by connecting ring 6, actuating motor is by transmission of power to worm screw, and worm screw passes to worm gear 2, and worm gear is again by output shaft outputting power.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed among the scope of the claims of the present utility model.
