[0020] The slewing support transfer device with an internal tooth limiting structure includes a transfer bracket 1 and an upper cover pressure plate 2. An internal tooth slewing support 3 is arranged between the transfer bracket 1 and the upper cover pressure plate 2. A plurality of inner expansion locking plates 101 are arranged above the transfer bracket 1. The inner expansion locking plates 101 are distributed in a ring shape. An adjusting slide groove 102 is provided at the bottom of the inner expansion locking plate 101. The inner expansion locking plate 101 is slidably connected to the transfer bracket 1 through the adjusting slide groove 102. A locking mouth 103 is provided on the outer side of the transfer bracket 1 and the upper cover pressure plate 2. The center hole area of the assembled internal tooth slewing support 3 is aligned with the inner expansion locking plate 101 and the supports are stacked on each other. After the slewing support is placed, the upper cover pressure plate 2 is installed on the top of the inner expansion locking plate 101, and the upper cover pressure plate 2 is used to expand and lock the inner expansion locking plate 101, so that the inner ring 302 of the support will not rotate during transportation.

[0021] Specifically, the internal gear slewing bearing 3 includes an outer ring 301 and an inner ring 302 , with rollers 303 provided between the inner ring 302 and the outer ring 301 , wherein the outer ring 301 and the inner ring 302 are rotatably connected via the rollers 303 .

[0022] Specifically, the inner ring 302 is installed on the outside of the inner expansion locking plate 101, wherein the outer surface of the inner expansion locking plate 101 is provided with rubber, and the inner side of the inner ring 302 is provided with a tooth mouth. The rubber structure on the surface of the inner expansion locking plate 101 can effectively enhance the friction resistance between the inner expansion locking plate 101 and the support after being bonded to the support. At the same time, the rubber material can also avoid providing protection to the slewing support of the inner tooth structure and avoid changes in the tooth mouth accuracy.

[0023] Specifically, a pressure cone 201 is provided at the bottom of the upper cover pressure plate 2, and the pressure cone 201 is connected to the upper cover pressure plate 2 through an internal thread. The pressure cone 201 adopts a narrow bottom and wide top design structure. After the pressure cone 201 enters the inner side of the inner expansion locking plate 101, it can adjust the outer expansion diameter between the three groups of inner expansion locking plates 101, so that the inner expansion locking plate 101 contacts the inner ring 302 to complete the locking.

[0024] Specifically, the pressing cone 201 is installed inside the inner expansion locking plate 101, and the pressing cone 201 fits the inner side of the inner expansion locking plate 101. The inner expansion locking plate 101 can be contracted and expanded outwardly through the sliding groove structure at the bottom, so that it can adapt to slewing bearings of different calibers.

[0025] Specifically, a rubber ring plate 202 is provided on the outside of the pressing cone 201, and the rubber ring plate 202 is connected to the upper cover pressure plate 2 through a slot. The rubber ring plate 202 can press and fix the slewing bearing below after the upper cover pressure plate 2 is closed, thereby preventing the slewing bearing from bumping and jumping during transportation.

[0026] Working principle: align the center hole area of the assembled internal gear slewing bearing 3 with the inner expansion locking plate 101 and put it on, and the supports are stacked on each other. After the slewing bearing is placed, install the upper cover pressure plate 2 on the top of the inner expansion locking plate 101. The pressure cone 201 at the bottom of the upper cover pressure plate 2 can adjust the outer expansion diameter between the three groups of inner expansion locking plates 101 after entering the inner side of the inner expansion locking plate 101, so that the inner expansion locking plate 101 contacts the inner ring 302 to complete the locking. The rubber structure on the surface of the inner expansion locking plate 101 can effectively enhance the friction resistance between the inner expansion locking plate 101 and the support after being fitted with the support. At the same time, the rubber material can also avoid providing protection to the slewing bearing of the inner gear structure and avoid changes in the tooth mouth accuracy.
