Description

Technical Field

[0001] The utility model relates to a mechanical connecting component, in particular to a connecting piece which can be used to connect a reducer and a photovoltaic support. Background Art

[0002] A reducer is a speed reduction transmission device used between the prime mover and the working machine, and is widely used in modern machinery. Common reducers usually use a small gear to drive a large gear to achieve a deceleration effect, and play the role of transmitting torque between the prime mover and the working machine or actuator.

[0003] In the photovoltaic power generation industry, the transmission gear of a reducer is typically connected to the rotating shaft of a photovoltaic adjustment bracket using connectors, enabling the bracket to track the sun. Existing connectors connect the transmission gear of the reducer and the rotating shaft of the adjustment bracket in a relatively simple manner, typically using flanges. This concentrates the rotational load on the connecting bolts during reducer rotation. High output power can easily cause deformation of the connecting bolts, leading to unstable transmission. Utility Model Content

[0004] In order to make up for the shortcomings of the existing connectors described in the background technology, the present application provides a connector that can be used to connect a reducer and a photovoltaic bracket, wherein a flange ring is fixedly connected to the end side of the square shaft, and a limiting block is fixedly arranged at the connecting end face of the flange ring and the edge of the square shaft. The end face of the flange ring is provided with at least one first connecting hole between two adjacent limiting blocks, and specifically there are two first connecting holes between each two adjacent limiting blocks, and the first connecting hole is specifically a through hole. The square shaft is a prism with an open outer end face, and a plurality of second connecting holes are provided on the side of the square shaft; the limiting blocks arranged in the above manner can form a structure similar to a spline, which can play a role in auxiliary connection and cooperation, so that there is no need to cover the entire flange ring with flange holes, and the use of connecting bolts can be reduced when the connector is connected through the flange ring.

[0005] The above-mentioned connector is used as follows:

[0006] In and reducer such as Figure 3 When the transmission gear is connected as shown, the end of the square shaft of the connecting piece close to the flange ring is placed on the inner ring of the transmission gear, the limit block of the connecting piece is placed in the limit groove corresponding to the transmission gear, and the connecting bolt passes through the first connecting hole of the connecting piece and is screwed into the threaded hole of the transmission gear. In this way, when the reducer is running, the square shaft of the connecting piece and the limit block can share the load of the connecting bolt, preventing the connecting bolt from being subjected to excessive rotational shear force and deformation;

[0007] When connecting with the rotating shaft of the photovoltaic adjustment bracket, the other end of the square shaft of the connector is sleeved on the rotating shaft through its opening. Of course, the rotating shaft is also a square shaft with a matching shape. When the square shaft of the connector is sleeved on the rotating shaft of the photovoltaic adjustment bracket, a connecting bolt passes through the second connecting hole of the connector and is screwed into the threaded hole on the rotating shaft for connection. In this way, during transmission, the main rotational load is also on the square shaft, which can withstand a larger rotational load, protect the connecting bolt from deformation, and ultimately make the transmission stable.

[0008] Preferably, the limit block is integrally connected to the square shaft and welded to the end face of the flange ring. The limit block provided in this way can provide the connecting piece with reliable structural strength.

[0009] Furthermore, the square shaft can be a square shaft, a hexagonal shaft or an octagonal shaft. In this specific embodiment, the square shaft is a hollow hexagonal prism, and the hollow inner wall of the square shaft protrudes around the second connecting hole to form a thickened wall; such a square shaft can reduce the weight of the entire connecting part, and while ensuring the strength at the second connecting hole by thickening the wall, it has the characteristics of lightweight, which not only saves manufacturing materials and reduces manufacturing costs, but also improves transmission efficiency by reducing its own load.

[0010] Through the above technical solution, the utility model has at least the following beneficial effects:

[0011] The connector described in the present application can be used to connect the reducer and the photovoltaic bracket, and its structure is stable and compact. In addition to setting a flange ring structure to connect with the transmission gear of the reducer, the square shaft and the limit block at one end thereof can share the load of the connecting bolt after cooperating with the transmission gear. The other end of the connector is also connected through the square shaft and the rotating shaft of the photovoltaic adjustment bracket. The main rotational load is also on the square shaft, which can withstand a larger rotational load, protect the connecting bolts from deformation, and make the transmission stable.
