The utility model provides a coaxial -type biax output speed reducer, simple structure, convenient to use, two output shafts having realized the speed reducer can export on the same output shaft line of same output and can the forward or the purpose of reverse output, have improved transmission efficiency, set up the temperature transducer and prevent the too high deterioration of oil that results in of oil temperature, are favorable to lubrication and the cooling of oil to the speed reducer gear, set up the oil stream play that the oil blanket prevented speed reducer inside, not only improved the life of speed reducer reduction speed reducer, reduced cost of maintenance moreover.

Description

A kind of coaxial-type double-shaft output reducer

Technical field

The utility model relates to speed reducer technical field, especially a kind of coaxial-type double-shaft output reducer.

Background technique

Speed reducer plays coupling rotating speed and transmitting torque between prime mover and working machine or actuator, speed reducer is a kind of relatively accurate machinery, its object is used to be reduce rotating speed, increase torque, application relates to the industry such as metallurgy, coloured, coal, building materials, boats and ships, water conservancy, electric power, engineering machinery and petrochemical industry.

But in actual use; often can use two output shafts to export on same output terminal and same output axis; and the object that can reach two output shaft forwards or oppositely export, to meet the technical requirements of working equipment, current existing speed reducer does not have function like this.

Model utility content

The technical problems to be solved in the utility model is: in order to two output shafts realizing speed reducer can export and the object that can export forward or backwards on the same output axis of same output terminal, the utility model provides a kind of coaxial-type double-shaft output reducer, be fixedly connected with output solid shaft by motor input shaft, export solid shaft in the axial direction through output hollow shaft, output solid shaft and described output hollow shaft coaxially export, thus two output shafts realizing speed reducer can export and the object that can export forward or backwards on the same output axis of same output terminal.

The utility model solves the technological scheme that its technical problem adopts: provide a kind of coaxial-type double-shaft output reducer, comprise motor input shaft, export the output hollow shaft of solid shaft, speed reducer and speed reducer, described motor input shaft is fixedly connected with output solid shaft, described output solid shaft is in the axial direction through output hollow shaft, and described output solid shaft and described output hollow shaft coaxially export.

Further, described speed reducer comprise be connected with motor speed reducer input shaft, the first gear, the second gear, worm screw, worm gear and decelerator shell, described speed reducer input shaft is arranged with the first gear, described first gear and the second gears meshing, described second geared sleeve is located on worm screw, described worm and wheel engagement, described worm gear set is located on described output hollow shaft.

Preferably, described speed reducer is provided with the temperature transducer for checking speed reducer oil temperature, prevents high oil temperature from causing deterioration of oil, is conducive to the lubrication and cooling of oil to reducer gear.

Preferably, between described decelerator shell and output hollow shaft, be provided with oil sealing, prevent the oil of speed reducer inside from flowing out, not only increase the working life that speed reducer reduces speed reducer, and reduce maintenance cost.

Particularly, described decelerator shell is connected by bearing with output hollow shaft.

Particularly, described output solid shaft is connected by bearing with output hollow shaft.

The beneficial effects of the utility model are: the utility model provides a kind of coaxial-type double-shaft output reducer, structure is simple, easy to use, two output shafts achieving speed reducer can export and the object that can export forward or backwards on the same output axis of same output terminal, improve transmission efficiency, arranging temperature transducer prevents high oil temperature from causing deterioration of oil, is conducive to the lubrication and cooling of oil to reducer gear; Arranging oil sealing prevents the oil of speed reducer inside from flowing out, and not only increases the working life that speed reducer reduces speed reducer, and reduces maintenance cost.
