Abstract
The invention discloses a gear ring for a flour mill, comprising two gear rings which are same, wherein the inner surface of each gear ring is longitudinally provided with a plurality of grooves, the two gear rings are stacked up and down, and the notches of the grooves on the two gear rings are completely aligned, thus the two gear rings are fixedly connected. The invention has the advantages that the two gear rings are adopted, the upper and lower gear rings can be timely changed when the middle part of the gear ring is seriously abraded, thus the service life of the gear ring can be prolonged, and each part of the gear ring can be completely utilized; the process is simple, and the gear ring is convenient to manufacture; the gear ring is simple and convenient to use, and no environmental pollution is produced; and the gear ring is especially applicable to an impact type smashing main machine of an LNI-660A type flour mill.
Description
Technical field
The present invention relates to the flour mill field, is a kind of flour mill gear ring specifically.
Background technology
When mincing material, the LNI-660A type mechanical kinetic energy abrasive dust that use at present at powder process station, pump house workshop mainly in impact type is pulverized main frame, carries out, impact type is pulverized main frame by pulverizing mill, tup, grind parts compositions such as gear ring, material is subjected to strong impact during pulverizing between tup and grinding gear ring, friction and shearing force and pulverized, equipment is in the process of running up, grind gear ring and be subjected to material, pulverize mill, the friction of tup, mid portion very easily weares and teares, and the upper and lower is excellent, main cause is to be installed in the medium position that grinds gear ring owing to pulverize mill, weares and teares more serious so grind the gear ring mid portion.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the object of the present invention is to provide a kind of flour mill gear ring, it can prolong the service life of gear ring, and each position of gear ring is all utilized; Can make operation simple, easy to make; Easy to use, non-environmental-pollution; Be particularly useful for LNI-660A type flour mill impact type and pulverize main frame.
Technical scheme: in order to solve the problems of the technologies described above, a kind of flour mill gear ring of the present invention, comprise two identical gear rings, on the inner surface of each gear ring and be provided with a plurality of grooves along the longitudinal, two gear rings are stacked together up and down and to make the notch of two grooves on the gear ring aim at the back fully fixedly connected.
Described groove is a circular arc.
Two gear rings are fixedly connected by hexagon socket head cap screw.
Beneficial effect: compared with prior art, advantage of the present invention is to adopt two gear rings, can be when the serious wear of gear ring middle part in time two gear rings be up and down changed use, can prolong the service life of gear ring like this, each position of gear ring is all utilized; Can make operation simple, easy to make; Easy to use, non-environmental-pollution; Be particularly useful for LNI-660A type flour mill impact type and pulverize main frame.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the local enlarged diagram at A place among Fig. 1.
The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, a kind of flour mill gear ring of the present invention, comprise two identical gear rings 1, on the inner surface of each gear ring 1, also be provided with a plurality of grooves 2 along the longitudinal, two gear rings 1 are stacked together up and down and the notch of two grooves 2 on the gear ring 1 is aimed at fully, and are by hexagon socket head cap screw that two gear rings 1 are fixedly connected then; Wherein said groove 2 is a circular arc.
To be applicable to that LNI-660A type flour mill impact type is pulverized main frame is example, the wall thickness of gear ring 1 is 33mm, the width of rebate of groove 2 is 18mm, the height of groove 2 is 10mm, spacing between groove 2 and the groove 2 is 10mm, on the wall of gear ring 1, be provided with 6 screws 3 and supply fixedly usefulness of hexagon socket head cap screw, make two screws of symmetry on the wall in addition respectively as loading and unloading lifting use.When making gear ring 1, must use wear-resisting carbon steel material.The spent material Mohs' hardness must be below 4 grades, and water content is less than 12%; Gear ring 1 need be done Wear-resistant Treatment.
During installation, at first check gear ring 1 as requested whether material made, whether size meets the requirements, whether parts complete etc.; Gear ring 1 is installed in the impact grinder main frame; Start operational outfit according to the flour mill operational procedure; Regularly chemically examine material moisture and hardness, requirement up to specification.
During use, gear ring 1 is checked fastening bolt and abrasion condition in operation after one month; Use after a period of time as find gear ring 1 middle part serious wear, in time two gear rings 1 are up and down changed, the part that makes the top wearing and tearing up, the part of bottom wearing and tearing continues to use down, weares and teares up to the middle part.
The above only is a preferred implementation of the present invention; be noted that for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
