Abstract
The utility model relates to a quickly disassembled and assembled pulley, which comprises a female wheel, wherein the female wheel is axially provided with a through hole, and a taper sleeve is arranged in the through hole; the taper sleeve and the female wheel are provided with screw holes, and the taper sleeve is tightly connected with the female wheel through screws; a cover plate is arranged outside the through hole, and the taper sleeve is connected and tightly matched with a motor through a key; and the female wheel is sleeved on the taper sleeve, and the female wheel is in transition fit with the taper sleeve. The quickly disassembled and assembled pulley has the characteristics of low production cost and high safety factors, and is convenient to install.
Description
Technical field
The utility model relates to a kind of belt pulley, particularly a kind of belt pulley of quick release combination.
Background technique
Present belt pulley has 2.5 times, 5 times, 7 times, 9 times and 12 inferior numerous kinds.Transfer ginseng frequent because " hypotonic, low pressure, low yield " in oil field can cause to a certain extent, during operating cost and have certain security risk, operation in the open air for a long time causes key and belt pulley joint to get rusty extremely can't to dismantle on motor in addition.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of belt pulley of quick release combination, can effectively alleviate labor intensity of operating personnel, simultaneously, because the Combination leather belt wheel is not fragile and the life-span lengthening, can effectively prevent the generation of accident, have characteristics easy to install and use, that operating cost is low, safety coefficient is high.
To achieve these goals, the technical solution adopted in the utility model is: a kind of belt pulley of quick release combination, include a female wheel, female wheel is provided with a through hole vertically, be provided with tapered sleeve in the through hole, tapered sleeve is equipped with screw hole with female wheel, and screw closely links together tapered sleeve and female wheel, and through hole is provided with cover plate outward.
Screw hole on described female wheel is other also to be provided with top wire hole, is provided with jackscrew in the top wire hole.
Described tapered sleeve is connected in the rotating shaft on the motor with key, and itself and motor are closely cooperated.
Described tapered sleeve side is provided with groove, female wheel and tapered sleeve transition fit.
The utility model is owing to be provided with tapered sleeve in mother takes turns through hole, and female wheel is fastening with screw with tapered sleeve, and tapered sleeve cooperates with key and closely is connected with machine shaft, fastening along with retaining screw when mounted of this tapered sleeve, and female wheel and tapered sleeve cooperation are tight more; Unclamp retaining screw in unloading process a little, tapered sleeve breaks away from following moment of effect and female wheel of self elastic force, has dismounting characteristics especially easily.

Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and working principle are described in further detail.
With reference to Fig. 1,4,5,: a kind of belt pulley of quick release combination, include a female wheel 1, female wheel 1 is provided with a through hole 2 vertically, is provided with tapered sleeve 4 in the through hole 2, tapered sleeve 4 usefulness keys 9 are connected in the rotating shaft 10 on the motor, itself and motor are closely cooperated, and tapered sleeve 4 is respectively equipped with screw hole 5, screw hole 3 with female wheel 1, and screw 8 closely links together tapered sleeve 4 and female wheel 1, the outer cover plates 7 that are provided with of through hole 2, cover plate 7 by screw with mother take turns 1 and tapered sleeve 4 and key 9 be fixed together.Screw hole 5 sides on female wheel 1 also are provided with top wire hole 12, are provided with jackscrew 11 in the top wire hole.
With reference to Fig. 2,3, described tapered sleeve 4 sides are provided with groove 6, female wheel 1 and tapered sleeve 4 transition fit; The purpose of groove 6 is to make tapered sleeve 4 to maintain elasticity, unclamps retaining screw in unloading process a little, and tapered sleeve breaks away from the following moment of effect and the belt pulley of elastic force, and it is convenient especially to dismantle.
Working principle of the present utility model is:
During use, earlier it is connected tapered sleeve 4 usefulness keys 9 with motor, fastening along with retaining screw when mounted of this tapered sleeve, female wheel and tapered sleeve cooperate tight more, mother is taken turns 1 to be enclosed within on the tapered sleeve 4, female wheel 1 is a transition fit with tapered sleeve 4, when transferring jig frequency, only need unclamp retaining screw a little, tapered sleeve breaks away from the following moment of effect and the belt pulley of self elastic force, and when mother's wheel was not automatically springed open by tapered sleeve, the rotation jackscrew can make female wheel break away from tapered sleeve, can install, change female wheel 1, have dismounting characteristics especially easily.
