Description

Technical Field

[0001] The present invention relates to the technical field of gear rings, and more specifically, to a large-sized split combined gear ring. Background Art

[0002] Super-large gear rings are very common in the machinery industry. For example, super-large gear rings can be seen on large equipment such as ball mills and rotary kilns, and they are widely used. However, limited by the size of mechanical processing equipment, currently, for super-large gear rings, it is very difficult to process them with conventional mechanical processing equipment. Even if a super-large gear ring is processed using an extra-large machine tool, later, the transportation and installation of the super-large gear ring are still big problems. Based on this, currently in the industry, super-large gear rings are designed in a segmented manner, that is, a whole gear ring is divided into several single-segment gear rings. The single-segment gear rings are small in volume, can be processed by ordinary machine tools, and are also very convenient for transportation. It only needs to assemble several single-segment gear rings into a complete gear ring later, which is very convenient.

[0003] And currently, the conventional assembly method of segmented gear rings is basically to drill holes at both ends of the single-segment gear rings, and then use connecting plates to fix and connect two single-segment gear rings with bolts. However, there are errors in the bolt connection itself, which easily leads to misalignment between single-segment gear rings; or after the bolts become loose, there will be a problem of misalignment between single-segment gear rings, which is not only troublesome to assemble but also poses risks during the operation of the gear ring. Summary of the Invention

[0004] The purpose of the present invention is to address the deficiencies of the prior art, and provide a large-sized split combined gear ring. The segmented gear segments are positioned and connected by a guide rail structure, and then fixed with bolts. It is not only convenient to assemble, but also when the bolts become loose, there will be no problem of misalignment or separation of the gear segments.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0006] A large-sized split combined gear ring includes several arc-shaped gear segments. The gear segments enclose and form a circular support ring. The gear segments are composed of two upper and lower opposite gear rings. On the inner end surface of the gear ring, a T-shaped card slot penetrating through both end surfaces of the gear ring is formed. On the inner end surface of the gear ring, several T-shaped slots penetrating through the outer wall of the gear ring are formed. Several engaging teeth are abutted against the outer wall of the gear segment. A T-shaped buckle block is formed at the root of the engaging tooth, and the buckle block is inserted into the T-shaped slot of the gear ring; an arc-shaped card strip with a cross-section in the shape of "I" is provided between adjacent gear segments, and the arc-shaped card strip is inserted into the T-shaped card slot of the gear ring; several fastening bolts are inserted into the inner wall of the gear segment, and the end of the fastening bolt is screwed and fixed on the arc-shaped card strip.

[0007] Preferably, there are at least six tooth segments, the central axis of the tooth segment coincides with the central axis of the arc-shaped clip, the number of the arc-shaped clip is equal to the number of the tooth segments, and the arc-shaped clip and the tooth segment are both ring-shaped around the central axis of the tooth segment.

[0008] Preferably, the meshing teeth are evenly distributed in a ring shape around the central axis of the tooth segment.

[0009] Preferably, a sink is formed on the inner wall of the gear ring and passes through the inner end face of the gear ring, and a socket connected to the T-slot is formed on the bottom surface of the sink. The fastening bolt adopts a hexagon socket bolt, the head of the fastening bolt is inserted in the sink, and the screw portion of the fastening bolt is inserted in the socket of the gear ring.

[0010] Preferably, the T-shaped slot and the T-shaped clamping slot on the gear ring are connected, and the arc-shaped clamping strip is composed of a vertical part in the middle and horizontal parts at both ends of the vertical part. The upper and lower end faces of the buckle block respectively abut against the horizontal parts of the arc-shaped clamping strip, and the inner end face of the buckle block is an arc surface and abuts against the outer wall of the vertical part of the arc-shaped clamping strip.

[0011] Preferably, the arc radius of the tooth segment is equal to the arc radius of the arc-shaped clamping strip, adjacent tooth segments abut against each other, adjacent arc-shaped clamping strips abut against each other, and a toggle groove connected to the T-shaped clamping groove and in an arc shape is formed on the outer end surface of a tooth segment in the support ring, and a clamping hole opposite to the toggle groove is formed on the arc-shaped clamping strip.

[0012] Preferably, the clamping hole of the arc-shaped clamping strip is located at one end of the toggle slot, and the arc angle of the toggle slot is equal to 1 / 2 of the arc angle of the tooth segment.

[0013] The beneficial effects of the present invention are:

[0014] (1) The segmented tooth segments are positioned and connected using a guide rail structure and then fixed with bolts. This is not only convenient for assembly, but also does not cause the problem of tooth segment separation and misalignment when the bolts are loosened.

[0015] (2) The combined gear ring is designed with the meshing teeth and the tooth segments as a split structure. When part of the meshing teeth is worn, the part of the meshing teeth can be replaced. BRIEF DESCRIPTION OF THE DRAWINGS
