Description

Technical Field

[0001] The utility model relates to a speed reducer transmission mechanism. Background Art

[0002] In the bar rolling steel cooling bed moving rack transmission device, the reducer and the transmission shaft are used to drive the cooling bed moving rack stepping action. It is usually necessary to add a counterweight to the reducer to play a certain role and reaction force in the start and stop process of the stepping reducer, so as to achieve the purpose of smooth start and stop of the stepping reducer.

[0003] In the counterweight installation structure of the existing reducer, the installation angle of the counterweight relative to the transmission shaft is often fixed. For example, in the technical solution disclosed in the publication number CN217130219U, the reduction gear containing the counterweight and the transmission shaft are keyed, and the angle between the reduction gear containing the counterweight and the transmission shaft cannot be adjusted. The transmission shaft and the reducer in the transmission mechanism are often indirectly connected, which causes the installation of the transmission shaft and the reducer to cause the angle of the counterweight relative to the reducer to deviate under actual working conditions, thereby affecting the smooth start and stop effect of the counterweight on the stepping reducer, and ultimately affecting the load capacity of the entire cooling bed.

[0004] Therefore, it is necessary to design a transmission mechanism with an adjustable counterweight installation angle, so that when it is found that the counterweight angle deviates from the design, the counterweight can be adjusted according to the angle in time. Utility Model Content

[0005] The utility model aims to provide a cooling bed transmission mechanism with an adjustable counterweight angle, that is, the angle of the counterweight relative to the transmission shaft is adjustable, so as to ensure the smooth effect of the counterweight on the start and stop of the reducer.

[0006] The technical solution adopted by the utility model to solve the above-mentioned problem is: a cooling bed transmission mechanism with adjustable counterweight angle, comprising: a reducer, a transmission shaft, a counterweight, an expansion coupling sleeve and a reducer, the expansion coupling sleeve is sleeved on the transmission shaft, the counterweight is then connected to the expansion coupling sleeve, the transmission shaft is connected to the reducer, and a circumferential contact surface is formed between the expansion coupling sleeve and the transmission shaft so that the expansion coupling sleeve can rotate around the transmission shaft under the action of an external force.

[0007] Preferably, the transmission shaft is connected to the output shaft of the reducer through a coupling.

[0008] Preferably, the expansion coupling sleeve is located at an eccentric position of the counterweight, and the eccentric effect of the counterweight is utilized to better play a buffering and balancing role on the action of the reducer.

[0009] Compared with the prior art, the advantages of the utility model are: in the present application, the counterweight is installed on the transmission shaft through an expansion sleeve, and the transmission shaft is then connected to the reducer, and the expansion sleeve and the transmission shaft have a matching structure of a circumferential contact surface, so that the angle of the expansion sleeve relative to the transmission shaft can be adjusted under the drive of an external force or when the expansion sleeve is decompressed, thereby achieving the adjustment of the installation angle of the counterweight, which makes it convenient for the operating personnel to timely correct the angle of the counterweight according to the actual working conditions on site to meet the design requirements.

[0012] The present invention is further described in detail below in conjunction with the accompanying drawings. The embodiments are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention. The text description in this embodiment corresponds to the accompanying drawings, and the description of the orientation is also based on the description of the accompanying drawings, and should not be understood as limiting the scope of protection of the present invention.

[0013] like Figure 1 As shown, the cooling bed transmission mechanism in this embodiment is mainly composed of a transmission shaft 1, a counterweight 2, an expansion sleeve 3, a coupling 4, and a stepping reducer 5. The transmission shaft 1 and the counterweight 2 are connected by the expansion sleeve 3, one side of the coupling 4 is connected to the transmission shaft 1, preferably in an interference connection mode, and the other side of the coupling 4 is connected to the output shaft of the stepping reducer motor 5. The edge of the counterweight 2 is connected to the expansion sleeve 3, and the counterweight 2 is eccentric relative to the transmission shaft 1. The expansion sleeve 3 is tightly attached to the outer circumference of the transmission shaft 1, and the load transfer between the transmission shaft and the counterweight is achieved through pressure and friction. The expansion sleeve 3 can be locked or released relative to the transmission shaft, so that the expansion sleeve 3 can rotate relative to the transmission shaft 1 to adjust the counterweight angle.

[0014] In the above transmission mechanism, by improving the connection mode between the transmission shaft and the counterweight, the counterweight angle can be adjusted when deviation occurs due to external factors, thereby meeting the design requirements.

[0015] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
