Abstract

The utility model discloses a driven shaft transmission, including driven shaft, bearing, snap ring, bearing sleeve and bearing end cover. In the transmission device, two tool withdrawal grooves are formed in the driven shaft, two spring snap rings can be respectively arranged on the two tool withdrawal grooves, and the bearing is arranged between the two spring snap rings to play a role in fixing the radial position of the driven shaft. The bearing end cover and the bearing sleeve penetrate through the driven shaft and then are installed on two sides of the frame to play a role in fixing the axial position of the bearing, and the driven shaft can fix the radial position and the axial position under the matching of the bearing, the bearing sleeve and the bearing end cover to transmit stable motion. The device simple structure, each spare and accessory part are installed and removed the convenience, can simplify the assembly process, and the overall structure size of transmission motion is less.

Description

Driven shaft transmission device

Technical Field

The utility model relates to a transmission specifically is a driven shaft transmission.

Background

The shaft is one of the main parts that make up the machine. All the transmission parts which do rotary motion, such as the wheels of the utility model, must be installed on the shaft to carry out the motion and the transmission of power. Because the factors influencing the structure of the shaft are various and the structure of the shaft is different according to different specific situations, the shaft has no standard structural form and has no fixing method during installation. The scheme of general assembly at present has through shoulder, sleeve, bearing retainer ring, bearing end cover and round nut to guarantee the axial positioning of epaxial part, and this type of part self size is great usually or for example adopt the shoulder to carry out part axial fixity, just must make the diameter of axle increase, and shoulder department can arouse stress concentration because the cross-section sudden change moreover, in addition, also does not benefit to processing when the shoulder is too much. For parts requiring circumferential fixation, such as the bearing sleeve and the bearing end cover, a key, a spline, a pin, and the like are generally used. The use of these components increases the difficulty of machining the components and also makes the overall structure more complex. Therefore, in the field of shaft transmission, motion transmission ensures that the motion transmission has enough strength, and meanwhile, the whole transmission device has a simple structure and compact size and becomes a trend of development. The current drive mechanism type is single, and the external dimension is great, inconvenient installation, and the maintenance cost is high. The utility model discloses, through the improvement to slave unit, make the structure more retrench, it is with low costs, it is convenient to maintain.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the not enough of current structural design method, provide a driven shaft transmission, solve general axle type motion transmission structure complicacy, the great problem of size.

In order to achieve the above purpose, the utility model provides the following technical scheme:

the driven shaft is connected with the bearing through the spring snap ring, the bearing is installed between the bearing sleeve, the bearing end cover and a frame, and the bearing sleeve and the bearing end cover are installed on the frame through bolts.

Furthermore, the driven shaft transmission device is arranged between the motor and the trolley hub, in the device, two spring snap rings are connected with the driven shaft through two tool withdrawal grooves on the driven shaft, and a bearing is arranged between the two spring snap rings. All threaded holes are formed in the bearing end cover, the bearing sleeve and the frame, the bearing end cover and the bearing sleeve are installed on two sides of the frame through bolts, the bearing is installed in an inner space between the bearing end cover and the bearing sleeve, and the driven shaft is axially and circumferentially fixed through the installation. The device is simple to install, easy to disassemble and compact in structure.

In the figure: 1. wheel, 2, bearing end cover, 3, frame, 4, bearing sleeve, 5, motor, 6, motor support, 7, hub, 8, key, 9, driven shaft, 10, spring snap ring, 11, bearing.

Detailed Description

The present invention is further explained with reference to fig. 1 and 2.

As shown in figure 1, the utility model provides a driven shaft transmission, including bearing end cover 2, frame 3, bearing sleeve 4, bearing end cover 2 and bearing sleeve 4 pass through the bolt and install in frame 3 both sides.

As shown in fig. 2, the internal parts of the driven shaft transmission device comprise a driven shaft 9, two spring snap springs 10, a bearing 11, a bearing end cover 2 and a bearing sleeve 4, wherein a tool withdrawal groove for installing the spring snap ring 10 is formed in the driven shaft 9, and the bearing 11 is fixed on the driven shaft 9 through the two spring snap rings 10. All there is the screw hole on bearing end cover 2, bearing sleeve 4 and the frame 3, is connected with frame 3 through the bolt, and the bearing 11 is installed in the inner space between bearing end cover 2 and bearing sleeve 4.

The device realizes the axial fixation of a bearing 11 through a spring snap ring 10; the device realizes the axial fixity of driven shaft 9 through bearing end cover 2 and bearing sleeve 4, and bearing end cover 2 and bearing sleeve 4 self realize circumference and axial fixity through the bolt.

For a better understanding of the present invention, the installation process is described in detail below with reference to the accompanying drawings: after the electric motor 5 is fixed on the support 6, its outer shaft is connected with the driven shaft 9 by profile connection. Two tool withdrawal grooves are formed in the driven shaft 9 and used for installing the spring snap ring 10, the bearing 11 is sleeved on the driven shaft 9, the spring snap ring 10 is installed on two sides of the bearing 11 through snap ring pliers, the bearing end cover 2 penetrates through the driven shaft 9 and the bearing sleeve 4 and is installed on two sides of the frame 3 through bolts, and the bearing 11 is installed between the bearing end cover 2 and the bearing sleeve 4. The other side of the driven shaft 9 connects the hub 7 through a key 8. The activation of the electric motor 5 causes the driven shaft 9 to rotate, which movement of the wheel rotation is achieved by a keyed connection 8 between the driven shaft 9 and the hub 7.
