Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the description of the present utility model, it should be noted that, directions or positional relationships indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., are based on those shown in the drawings, are merely for convenience of description and simplification of the description, and do not indicate or imply that the apparatus or elements to be referred to must have a specific direction, be constructed and operated in a specific direction, and thus should not be construed as limiting the present utility model; the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance, and furthermore, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "coupled" are to be construed broadly, e.g., as being either fixedly coupled, detachably coupled, or integrally coupled; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

Referring to fig. 1-3, one embodiment provided by the present utility model is: the utility model provides a sprocket can be dismantled to three formula, includes wheel core 1, and peg graft in the back of wheel core 1 has pin-connected panel sprocket 2, and the front rotation of wheel core 1 is connected with fixing bolt 3, and bolt hole 4 has been seted up in the front of pin-connected panel sprocket 2, and fixing bolt 3's outer wall is provided with big flat pad 5.

A three-piece detachable chain wheel is characterized in that the chain wheel rim is conveniently replaced periodically under the condition of not changing the function of the chain wheel, the chain wheel rim is connected by adopting a mode of fastening fixing bolts 3 after three pieces of 120-degree butt joint assembly, one piece of the chain wheel rim is adjusted to be in non-contact with a chain under the condition of shutdown maintenance, the corresponding fixing bolts 3 are detached, the new chain wheel rim is taken off, the new chain wheel rim is assembled and fastened in place by the new fixing bolts 3, the replacement work of the chain wheel is completed by repeatedly completing the replacement work of the three chain wheels,

Specifically, the fixing bolts 3 are rotationally connected with the assembly type chain wheel 2 through the wheel core 1, and the number of the fixing bolts 3 is a plurality of groups, so that the connection is firmer;

specifically, the tooth-shaped surface quenching of the assembled sprocket 2 is HRC50-60, the depth of the tooth-shaped surface quenching of the assembled sprocket 2 is 5-8 mm, the surface strength is increased, and the service life is prolonged;

Specifically, the rim inclination angle of the assembly type chain wheel 2 is thirty degrees, and the matched chain of the assembly type chain wheel 2 is a P=101.6 chain, so that the meshing effect is good.

Working principle: the detachable assembled chain wheel 2 is a main transmission part on a head assembly on the elevator, and has the main functions of driving a chain and a hopper on the chain to do rotary reciprocating rotation work through the gear rotation of the assembled chain wheel 2 so as to achieve the purpose of continuously lifting the hopper, the power of the assembled chain wheel 2 is from a gear motor to drive a main shaft in the middle of a head wheel to move so as to drive the chain wheel to move, (the head wheel is connected with the main shaft through a flat key), the main shaft is connected with a gear motor through a flat key, and the gear motor rotates to drive the main shaft to drive the head wheel to synchronously run, so that the assembled chain wheel is suitable for the conditions that the rim loss of the chain wheel of the industrial elevator is relatively fast or the replacement of an object is relatively heavy, and the assembly recovery requirement precision is relatively high.

Finally, it should be noted that: the foregoing description is only illustrative of the preferred embodiments of the present utility model, and although the present utility model has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present utility model.
