Description
Technical Field
The utility model relates to a shaft coupling field, in particular to shaft coupling for pump convenient to dismantle.
Background
The coupling is a device which connects two shafts or a shaft and a rotating part, rotates together in the process of transmitting motion and power and does not separate under normal conditions.
The shaft coupling body and the fixed joint are directly sleeved in the original shaft coupling for the pump, the fixed joint and the output shaft are fixed through threads, and are required to be disassembled and assembled step by step during disassembly and assembly, so that the shaft coupling body deviates in the axis direction after long-time operation and abrasion, and can be clamped and difficult to disassemble when the fixed joint is disassembled.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a shaft coupling for pump convenient to dismantle, this shaft coupling combination is convenient, whole dismouting, simple operation.
In order to solve the technical problem, the utility model discloses a technical scheme does:
the utility model provides a shaft coupling for pump convenient to dismantle, includes the shaft coupling body, this internal fixed joint that is equipped with of shaft coupling, the retaining ring is established to the cover on the fixed joint for the hole, the inside processing of shaft coupling body has the retaining ring mounting groove, the hole is hidden in the retaining ring mounting groove with the retaining ring, fixed joint divide into extension end and installation end, the ring channel is seted up to the installation end surface, installation O type circle in the ring channel.
Preferably, two groups of mounting grooves are symmetrically arranged on the outer surface of the coupler body.
Preferably, the length of the fixed joint is one third of the length of the coupling body.
Preferably, the cross section of the extension end and the cross section of the mounting end are both circular, and the diameter of the extension end is smaller than that of the mounting end.
By adopting the technical scheme, the fixed joint is inserted into the coupler body by adding the retainer ring for the hole to form a combination, and the coupler body is also detached together with the fixed joint during use, so that the disassembly and the assembly are convenient.

In the figure, 1-a coupler body, 2-a hole retainer ring, 3-a fixed joint, 4-an O-shaped ring, 5-a retainer ring installation groove and 6-a flat groove.
Detailed Description
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", and the like, indicate the orientation or positional relationship indicated based on the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
The following description of the present invention will be made with reference to the accompanying drawings 1-3. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The utility model provides a shaft coupling for pump convenient to dismantle, including shaft coupling body 1, be equipped with fixed joint 3 in the shaft coupling body 1, fixed joint 3 goes up the cover and establishes hole retaining ring 2, 1 inside processing of shaft coupling body has retaining ring mounting groove 5, hole retaining ring 2 hides in retaining ring mounting groove 5, fixed joint 3 divide into extension end and installation end, the ring channel is seted up to the installation end surface, installation O type circle 4 in the ring channel constitutes a whole with fixed joint 3 and shaft coupling body 1 through hole retaining ring 2 and retaining ring mounting groove 5's cooperation, and integral erection and whole dismantlement when using reduce the dismantlement probability of bringing of part wearing and tearing and are hindered.
Preferably, two groups of flat grooves 6 are symmetrically arranged on the outer surface of the coupler body 1, and the flat grooves 6 facilitate the installation and positioning of the coupler body 1.
Preferably, the length of the fixed joint 3 is one third of the length of the coupling body 1.
Preferably, the cross section of the extension end and the cross section of the mounting end are both circular, and the diameter of the extension end is smaller than that of the mounting end.
The embodiments of the present invention have been described in detail with reference to fig. 1-3, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; may be mechanically coupled, may be electrically coupled or may be in communication with each other; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
