Abstract
The invention relates to a special shaft coupling for a grinding mill, which comprises a left half shaft coupling, a right half shaft coupling, bar pins and an outer collar, wherein the bar pins are uniformly mounted in the cavity which is defined by the assembly of the outer collar, the left half shaft coupling and the right half shaft coupling; protrusions are uniformly distributed on the outer cylindrical surface of the outer collar; and the protrusions are toothed-shaped or finger-shaped, and the bottom parts of the protrusions are all integrally connected with the outer cylindrical surface of the outer collar. During maintenance of the grinding mill, the shaft coupling is rotated only by mounting the bushings to the finger-shaped protrusions or pushing the profiles of the protrusions by the crow, so that the pinion shaft is driven to rotate and the drum is moved by the pinion, as a result, the manhole is moved to the desired position. The special shaft coupling for the grinding mill has a simple structure and is convenient to operate; and solves the problem in the prior art that the gear cover needs to be dismounted, the pinion is pushed by the crow to rotate the drum of the grinding mill, and the tooth surface of the pinion is liable to be damaged due to the crow.
Description
Technical field
The present invention relates to a kind of coupling, particularly a kind of special-purpose coupling that is used for grinding machine.
Background technique
Present known large-sized grinder all has slow transmission device so that when maintenance manhole can be parked in the position that needs.And small-sized grinding machine does not dispose this covering device owing to the reason of cost.For the grinding machine manhole being parked in the position that needs, the workman usually pulls down gear cover during maintenance, prizes small gear to drive the grinding mill barrel rotation, so that manhole is parked in the position that needs with crowbar.Do making maintenance very inconvenient like this, and therefore the flank of tooth of small gear damages easily also.
Summary of the invention
The special-purpose coupling that the purpose of this invention is to provide a kind of grinding machine.
The technological scheme that the present invention adopts is: a kind of special-purpose coupling of grinding machine; Comprise left half-coupling, right half-coupling, rod pin and outer collar; Rod pin is uniformly distributed with and is installed in outer collar and assembles with left half-coupling and right half-coupling and join in the hole that gets out, and the external cylindrical surface of said outer collar is provided with the double wedge that is uniformly distributed with.That said double wedge comprises profile of tooth or finger-like, their bottom all fuses with the external cylindrical surface of outer collar.When grinding machine overhauls, only need casing pipe sleeve be prized the profile of tooth of double wedge on the finger-like double wedge or with crowbar, drive coupling and rotate, rotate thereby drive pinion shaft, drive cylindrical shell through small gear, make the position that manhole forwards to be needed.
The invention has the beneficial effects as follows simple in structure, easy to operate.In grinding machine when maintenance, only need prize the profile of tooth of double wedge with casing pipe sleeve on the finger-like double wedge or with crowbar, drive coupling and rotate, and rotates thereby drive pinion shaft, drives cylindrical shell through small gear, makes the position that manhole forwards to be needed.Avoid need gear cover being pulled down before this, prize small gear with crowbar and rotate, and therefore damage the flank of tooth of small gear easily to drive grinding mill barrel.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is Fig. 1 left view.
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
