Description

[Detailed description of the invention] A percussion actuator in the radial direction rotatably supported on a driven and rotating eccentric body. Detailed Description of the Roller/Milling Tool Invention The invention relates to a radially rotatably mounted eccentric body which is driven to rotate. Concerning percussion-acting roller/milling tools.

Especially unbalanced or linearly excited/activated roller drilling tools Reeds, such roller drilling tools can drill large holes in hard rocks, etc. with minimal pressing force. However, in this case there are vibration problems as well as high technical costs. Difficulties exist regarding usage and energy consumption. The invention is relatively simple and Sturdy and with the possibility of various variations, each eccentric body is equipped with a perforation rod. Or #EA to roll independently! II and milling Dk Rotatably supported to do so. In this case, one or both 9111 In one embodiment, the held units are grouped in pairs and balanced. It may also be unbalanced. Such units may be individually or As a knit, rotated continuously or intermittently to create perforations or slits. can be formed, in which case the unit runs into the slit or perforation every minute Eccentric rotation speed of 4000 rpm, amplitude of 5 mm and toothed rim on the perforating roller. With the diameters or diameter differences mentioned, the perforating roller has 4000 percussions per minute and approximately 2 per minute. Milling is performed continuously at 00 rpm. If necessary, the blowing action can also be done from the inside. from the outside due to unbalance or other impact pulses. be converted into A separate application for protection will be filed for this. In particular, eccentric bodies rotating at high speed and/or increase the opposing moment or impact force on the punching roller rotating at low speed. Separately for the provision of additional spring bodies/balance masses to Agricultural insurance is applied for.

However, when it comes to the control/adjustability of unbalanced masses, the processing Toothed rim diameters or diameter differences related to the feathers and the respective eccentric selection Separate protection will also be applied for.

Brief description of the drawing In Figure 1, 1 is a radially vibrating and rotating drilling/cutting tool, and 2 is a radially vibrating and rotating drilling/cutting tool. , the drilling/cutting tool 1 is rotatably mounted, for example on the casing of the motor or is an eccentric body, 3 is a holding body, 4Fi driven or supported or This is the shaft of the motor held in a fixed position by the holding body 3, and 5 is held in the embodiment. A small toothed rim fixed to the body 3, 6 a seal in which a separate protection is inserted. A sealing disc with a lip fixed to a large toothed rim 7. this The toothed rim is also connected to a drilling/cutting tool 1 along a small toothed rim 5. Only in one direction, eccentrically, with forced rotation or as a ratchet Roll while locking. 8Vi as weight phase compensation for balanced rotation 1) In some cases, an unbalanced mass body can completely emit light. Second In the figure, 9 and 10 are bored holes rotatably supported on an eccentric body (not shown). perforation rollers 9 and 10 each having its own eccentric drive. It has a drive shaft that can be driven in the same direction, in opposite directions, balanced or unbalanced. In this case, the holding east supports 11 and 121d are rigid (even if they are connected). or may be held together or individually or elastically. 15 lines, width It is a tool that performs a wide range of tasks, and there are no arbitrary limits related to the diameter of the tamper, drilling/milling roller. (see 16) or separately cut Ai It is a tool that cuts two separated slits in which the web to be removed remains ( Separate protection will be applied for this). Both holders 11 and 12 are tightly connected If the direction and speed of rotation of both eccentrics are the same when f'i, 17 is provided with a pin, threaded part or similar as a rigid joint. You can get kicked. However, it is also possible that two or more eccentric bodies consisting of one body are separated. may be balanced and operate in a balanced state; Separate protection is applied for, and furthermore, the drive on one side 1 may be For the purpose of making it possible with a supporting and holding body on the side, the eccentric shaft is In order to drive the eccentric body of the Separate protection has also been filed against Separate protection will also be applied for.
