Abstract
The utility model discloses a sectional type bull gear. The entire bull gear is equally divided into 7-25 tooth sections, and every two adjacent tooth sections are connected via bolts. The sectional type large tooth ring is characterized by easy processing and high quality controllability.
Description
Technical field
The utility model relates to the bull gear in the turning round equipment drive unit, particularly the segmented bull gear.
Background technique
Traditional segmented bull gear is generally two sections or maximum four sections, only carries out necessary heat treatment.Sometimes also can adopt welded-steel plate construction.The tradition gear ring is because each fragment size is still very big, casting quality control and heat treatment installation all are difficult to meet the demands, this just causes blank to tend to repair with repair welding, finally influences the complete performance of gear ring, even causes the overproof use of one-piece parts size.
The model utility content
The purpose of this utility model is for providing a kind of processing, segmented bull gear that quality controllability is high of being easy to.
The technological scheme that realizes the foregoing invention purpose is as follows:
Segmented bull gear, whole gear ring are divided into 7～25 tooth sections, connect with bolt between two adjacent tooth sections.
The utlity model has following advantage:
1. casting easily: because each fragment size is very little, casting quality is controlled easily, can effectively avoid the cold crack defective that often occurs on traditional gear ring.
2. have processed edge, less because of each fragment size, can use the process equipment in the manufactory and do not need the input of extra special process equipment, save cost greatly.
3. convenient transportation: in manufactory and use in-situ processing gear ring segmentation single or combination easy more, do not need the means of transportation of special use than traditional gear ring.The segmented bull gear can use the shipping container of standard to transport fully.
4. quality is controlled easily: because each fragment size is very little, single blank cost of spoiled goods is lower, so whole gear ring only uses no cold crack, flawless gear ring segmentation.Situations such as the repair welding in the manufacturing of tradition gear ring, dimension overproof reuse are stopped by strictness.
5. it is convenient to change: when the single split accidental damage on the bull gear, new gear ring segmentation can replace impaired part very easily, and equipment is resumed production fast.Change or wait for when damaged condition is bigger in the future integral replacing again and need not resemble traditional gear ring whole gear ring removed.
6. delivery date is short: modular design, single hop production, overall package.Ensure in time delivery date reliably so can realize production fast.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As depicted in figs. 1 and 2, segmented bull gear, whole gear ring are divided into 7～25 tooth sections, connect with plain bolt 1 between two adjacent tooth sections, and locate with articulation hole bolt 2.Present embodiment will be put in order gear ring and be divided into 16 tooth sections.
The tooth hop count that whole gear ring is divided into and the number of teeth of each tooth section can be set as the case may be, provide several modes below for your guidance:
1. modulus 20, every section number of teeth 17-22;
2. modulus 25, every section number of teeth 13-17;
3. modulus 30, every section number of teeth 11-14;
4. modulus 40, every section number of teeth 8-10.
