Description

Technical Field

[0001] The utility model relates to the technical field of encoders, in particular to a coaxial encoder mounting bracket. Background Art

[0002] An encoder is a device that compiles and converts signals or data into a form that can be used for communication, transmission, and storage. It is commonly used to measure information such as motor speed and position. The encoder can be coaxially connected to the motor or mounted on the shaft being measured. Although certain precision requirements exist for concentricity between the encoder and the shaft during installation, it is not possible to guarantee perfect concentricity between the shaft and the encoder axis during actual installation. Current external encoders installed on wheel-mounted hydraulic motors can cause abnormal and severe damage to the encoder, resulting in inaccurate data transmission and the inability to achieve precise control. Utility Model Content

[0003] The purpose of the present invention is to provide a coaxial encoder mounting bracket to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a coaxial encoder mounting bracket, comprising a Z-shaped mounting bracket and an encoder, a support plate welded to the upper side of the mounting bracket, the encoder mounted on the outer side of the support plate, an axle seat mounted on the upper outer side of the mounting bracket, an axially penetrating rotating shaft rotatably connected to the middle of the axle seat, a concentric gear mounted on the rotating shaft, and the rotating shaft and the input shaft of the encoder being connected via an elastic coupling.

[0005] Preferably, two through holes are symmetrically provided on the lower portion of the mounting frame, and the through holes are waist-shaped holes.

[0006] Preferably, the mounting frame is formed by bending sheet metal and the thickness of the sheet metal is not less than 2 mm.

[0007] Preferably, the elastic coupling comprises two rigid half couplings, and a connecting elastic block is provided between the two half couplings.

[0008] Compared with the prior art, the beneficial effects of the present invention are: the present invention effectively avoids abnormal damage to the encoder input shaft caused by radial force and poor coaxiality, greatly extending the service life of the encoder and the accuracy of data transmission.

[0012] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0013] See also Figure 1-2 The utility model provides a technical solution: a coaxial encoder mounting bracket, including a Z-shaped mounting bracket 1 and an encoder 6, two through holes 7 are symmetrically provided on the lower part of the mounting bracket 1, and the through holes 7 are waist-shaped holes. The mounting bracket 1 is formed by bending sheet metal and the plate thickness is not less than 2 mm. A support plate 8 is welded on the upper side of the mounting bracket 1, and the encoder 6 is installed on the outer side of the support plate 8.

[0014] A shaft seat 2 is mounted on the outer side of the upper portion of the mounting frame 1. A rotating shaft 4 extending axially through the middle of the shaft seat 2 is rotatably connected. A concentric gear 3 is mounted on the rotating shaft 4. The rotating shaft 4 is connected to the input shaft of the encoder 6 via an elastic coupling 5. The elastic coupling 5 comprises two rigid half-couplings, with an elastic block connected between the two half-couplings. When the wheel-side reducer is operating, the speed and position information is proportionally transmitted to the encoder through gear transmission to achieve precise control. During the transmission process, the encoder is always in a follow-up state due to the radial and axial force transmission between the gears. The force point and direction are all borne by the shaft fixing device, thereby achieving precise concentric rotation position data transmission and control without being affected by radial force, which is conducive to extending the service life of the encoder.

[0015] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
