Problems solved by technology

However, the star wheel speed control device still has shortcomings in the structural design, such as the large diameter of the drum, which requires too many bearings to make it inconvenient to support at both ends, and the lack of sufficient support from the machine base, resulting in two internal The transmission between the large transmission mechanisms is not stable enough
In addition, the speed control device is not versatile enough to be applied in the field of large industrial test benches

[0040] Embodiment 1: As shown in FIG. 1, the planetary governor includes a base 4 in which a main power flow transmission mechanism and a secondary power flow transmission mechanism are connected by a coupling disk 6.

[0041] In this embodiment, the main power flow transmission mechanism adopts a single-pair double-row planetary gear transmission mechanism, and the secondary power flow transmission mechanism adopts a single-row planetary gear reduction mechanism to form a two-disk combined planetary gear transmission mechanism, and the transmission pair adopts bevel gear pairs. .

[0042] A low-speed output speed regulating device is formed by a single-pair double-row planetary gear transmission mechanism, a bevel gear pair-single-row planetary gear reduction mechanism.

[0043] The single-pair double-row planetary gear transmission mechanism includes: an internal gear 26 connected with the main power shaft 19, a first internal gear 5 connected with the coupling plate 6, a first ...

Embodiment 2

[0054] Embodiment 2: As shown in Figure 2, compared with Embodiment 1, this embodiment has the same secondary power flow transmission mechanism, and a planetary gear transmission mechanism is added to the main power flow transmission mechanism, that is, the main power flow transmission mechanism includes Two pairs of double-row planetary gear transmission mechanisms with different structures. In this way, this embodiment is mainly composed of two pairs of double-row planetary gear transmission mechanisms, a bevel gear pair-single-row planetary gear reduction mechanism together to form a three-disc combination with high speed output (the output speed can be lower or higher than the main motor speed) Speed ​​regulating device.

[0055] In the main power flow transmission mechanism, the two pairs of double-row planetary gear transmission mechanisms include a pair of double-row planetary gear transmission mechanisms that have been described in Embodiment 1, that is, the first internal...

Embodiment 3

[0060] Embodiment 3: As shown in FIG. 3, in this embodiment, the structure of the main power flow transmission mechanism is the same as that of Embodiment 1, and the secondary power flow transmission mechanism adopts a bevel gear pair-star gear transmission mechanism. That is, it is mainly a two-disk combined speed regulating device composed of a single pair of double-row planetary gear transmission mechanism and a bevel gear pair-star gear transmission mechanism.

[0061] The single-pair double-row planetary gear transmission mechanism has been described in the first embodiment.

[0062] In the bevel gear pair-star gear transmission mechanism, the bevel gear pair includes a small bevel gear 14 and a large bevel gear 17 connected with the control shaft 15.

[0063] The planetary gear transmission mechanism includes: a hollow sleeve 20 with a double crank eccentric sleeve 45 fitted on the large bevel gear 17, a third internal gear 41 fixed on the base 4, two technical parameters ar...

Abstract

The invention discloses a planetary speed regulator. The planetary speed regulator comprises a frame (4) inside which a main power flow transmission mechanism and an auxiliary power flow transmission mechanism are arranged and connected to each other via a coupling disk (6). The main power flow transmission mechanism is a planetary gear transmission mechanism and arranged in a way that the input end thereof is coupled with a main power shaft (19) and the output end thereof is coupled with an output shaft (1). An auxiliary power flow transmission mechanism is a planetary gear transmission mechanism or planetary transmission mechanism. A control shaft (15) is coupled with the auxiliary power flow transmission mechanism via a transmission pair. The planetary speed regulator has the advantages of small size, high transmission efficiency, low energy and material consumption and wide application range, and is suitable for the use in large-power and medium-power equipment.

Description

Technical field [0001] The invention relates to a gear transmission device, in particular to a planetary governor. Background technique [0002] One of the common shortcomings of the existing general-purpose reducer and governor is that the product structure is not uniform, the structure is complex, and the parts are numerous. It is difficult to achieve large-scale centralized production. Most reducer factories are labor-intensive enterprises. These defects lead to Its consumables are high, production efficiency is low, and resources are not fully utilized. In addition, the reducer and governor in the prior art still have the defect that once a failure occurs, all the parts of the reducer or governor must be disassembled for maintenance. The troubleshooting time is long and the maintenance is inconvenient. And affect production. [0003] The Chinese patent document with the application number 200510098385.0 discloses a star-wheel speed regulating device, which includes a planetar...
