Description

One input three output small gearbox

technical field

The utility model relates to the technical field of gearboxes, in particular to a small gearbox with one input and three outputs.

Background technique

For equipment with compact space, complex structure and many components, such as textile machinery, the simpler and more compact the structure of the power equipment, the higher the output capacity, the better. The power components of the existing equipment generally need to be equipped with multiple gearboxes to achieve multiple output speeds. First, the cost is high, the second is that it takes up too much space, and the third is that the maintenance is troublesome and needs to be improved.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the above-mentioned background technology, and provide a small gearbox with one input and three outputs, which has a simple and compact structure, strong output capability, three output speeds, and a wide range of applications.

The technical scheme of the present utility model is as follows:

A small gearbox with one input and three outputs, including a box, a worm installed in the box, a worm gear matched with the worm, and a speed change output shaft. The worm is used as the input end to connect with the motor, and both ends of the worm shaft extend out of the box to serve as a speed changer. The first output end and the second output end of the box, one end of the variable speed output shaft protrudes from the box body, as the third output end of the gearbox; the first driving gear and the second driving gear are fixedly installed on the worm gear shaft, and the variable speed output shaft The first driven gear is installed through the first bearing, and the second driven gear is installed through the second bearing. The first driven gear meshes with the first driving gear, and the second driven gear meshes with the second driving gear. A first hydraulic clutch matched with the first driven gear and a second hydraulic clutch matched with the second driven gear are fixedly installed on the output shaft, and the first hydraulic clutch and the second hydraulic clutch are not closed simultaneously.

Preferably, the hydraulic clutch is a wet multi-plate hydraulic clutch.

The utility model has the beneficial effects that the utility model utilizes two clutches to work staggered, so that the speed change output shaft can output two speeds, the entire gearbox has three output ends, and can drive three components at the same time, and the overall structure is simple and compact, Easy to use and save space.

Description of drawings

Figure 1 is a schematic structural diagram of the present invention.

Detailed ways

The present utility model will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1, a small gearbox with one input and three outputs includes a box 1, a worm 2 installed in the box through a bearing 7, a worm wheel 3 matched with the worm, and a transmission output shaft 10 installed in the box through the bearing, The worm is connected to the motor as the input end, and the two ends of the worm gear shaft 4 protrude out of the box body as the first output end 8 and the second output end 9 of the gearbox. Three output terminals 17 .

The first driving gear 5 and the second driving gear 6 are fixedly mounted on the worm gear shaft, the first driven gear 12 is mounted on the transmission output shaft 10 through the first bearing 11 , and the second driven gear 15 is mounted through the second bearing 16 . , the first driven gear meshes with the first driving gear, the second driven gear meshes with the second driving gear, and the speed change output shaft is fixedly installed with a first hydraulic clutch 13 that cooperates with the first driven gear, and is connected with the second driven gear. The second hydraulic clutch 14 is matched with the moving gear, and the first hydraulic clutch and the second hydraulic clutch are not closed at the same time.

Obviously, the transmission ratio between the first driving gear and the first driven gear and the transmission ratio between the second driving gear and the second driven gear are different. The hydraulic clutch is a wet multi-plate hydraulic clutch.

The working principle of the utility model is as follows: the motor drives the worm, the worm wheel rotates, and the two ends of the worm wheel shaft can respectively drive two parts with the same speed; when the first and second hydraulic clutches are not closed, the first and second driving gears are respectively Drive the first and second driven gears to idle, and the speed change output shaft does not rotate. When either the first hydraulic clutch or the second hydraulic clutch is closed, the speed change output shaft will rotate, and the speed of rotation is not the same, the speed change output shaft can be drive a component.

The above descriptions are only preferred embodiments of the present invention, and for those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
