Description

Aluminium alloy double reduction unit

Technical field

The utility model relates to a kind of reductor, especially relates to a kind of aluminium alloy double reduction unit.

Background technology

Reductor is a kind of power transmission mechanism, utilizes the velocity transducer of gear, and the winding number of motor (motor) is decelerated to desired winding number, and obtains the mechanism of larger torque. in the current mechanism for transferring power and motion, the range of application of reductor is quite extensive. almost in the transmission system of various machinery, can see its trace, from boats and ships, automobile, the locomotive of the vehicles, heavy machinery for building, the machining machine and tool that mechanical industry is used and automated production equipment, to common household electrical appliances in daily life, clock and watch etc. Chinese patent discloses a kind of shock resistance gear reduction unit (Granted publication number: CN203272734U), it comprises housing, input gear unit and output gear are installed on housing, between input gear unit and output gear, be connected by gear teeth wheels, gear teeth wheels comprise first-level variable-speed gear, the three-stage speed change gear that the power transmission shaft of two stage speed change gear is installed and is connected with output gear, first-level variable-speed gear is arranged on the power intake of power transmission shaft and is connected with input gear unit, two stage speed change gear is arranged on the clutch end of power transmission shaft and engages with three-stage speed change gear, the inner chamber of housing is provided with the supporting station for power transmission shaft is installed, power transmission shaft is arranged on supporting station by bearing, the inner chamber of supporting station is provided with the axial location step matching with bearing, supporting station is located at the bottom of housing inner chamber, and bearing is dark cylinder roller bearing, and two stage speed change gear and three-stage speed change gear are bevel gear, and input gear unit comprises the power input terminal pad for being connected with extraneous motor. but this reductor just utilizes gear drive, or more existing decelerators only use Worm Wheel System, and the mode of transmission is comparatively single, and connect while adopting Multi-stage transmission comparatively complicated.

Utility model content

The utility model is to provide a kind of aluminium alloy double reduction unit, it is mainly to solve the existing reductor of prior art just to utilize gear drive, or more existing decelerators are only used Worm Wheel System, the mode of transmission is comparatively single, and adopts and connect comparatively complicated etc. technical problem when Multi-stage transmission.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:

Aluminium alloy double reduction unit of the present utility model, comprise one-level input reducer shell, described one-level input reducer shell, one-level input reducer shell is provided with primary input axial, primary input axial is connected with one-level output shaft by worm and gear, the input flange of one-level input reducer shell directly connects secondary output speed reducer housing, the volume of one-level input reducer shell is greater than the volume of secondary output speed reducer housing, in secondary output speed reducer housing, be provided with worm and gear and the defeated place of secondary axle, one-level input reducer shell, secondary output speed reducer housing is all Al-alloy casing. the reductor input flange that the utility model is less can directly be connected with one-level input reducer shell, connects like this without separately doing flange, and assembling more for convenience.

As preferably, the inner surface of described one-level input reducer shell is provided with dustproof groove, and dustproof groove internal cavities width is greater than its A/F. Dust can be retained in dustproof groove to better dust removal effect by dustproof groove.

As preferably, the inner surface of described one-level input reducer shell is provided with acoustical cotton, and acoustical cotton is embedded in the T font caulking groove of one-level input reducer shell inner surface. The noise absorption that reductor can be sent by acoustical cotton is lived.

Therefore, the reductor that the utility model is less can directly be connected with upper level reductor by input flange, and without separately making adpting flange, production cost is lower, assembles comparatively simply, and dust-proof effect is better, and the noise of generation is less, simple and reasonable for structure.
