Abstract
A kind of belt conveyer draw-gear is the utility model is related to, i.e. circulation lubrication electric roller with external.It includes roller, there is bearing at roller both ends, roller input has right flange shaft, motor is realized by shaft coupling, right flange shaft, connection flange and is connected with roller, input shaft passes through bearings at both ends and right flange axis connection, roller is driven to rotate by gear drive thereon on input shaft in roller, it is characterised in that input shaft shaft end is connected by tapered shaft end with first gear in roller, has the oil-through hole for being passed through output shaft in corresponding right flange shaft.First gear uses taper connection with input shaft connection place, improves the contact length of key, and add pretightning force.Oil-through hole is provided between right flange shaft and input shaft, lubricating oil can enter in input shaft, realize lubrication to left support bearing, right support bearing, improve bearing service life.
Description
Technical field
A kind of belt conveyer draw-gear is the utility model is related to, i.e. circulation lubrication electric roller with external.
Background technology
In the prior art, motorized pulleys include roller, and there is bearing at roller both ends, and roller input has right flange shaft, electricity
Machine gos deep into right flange shaft realization by input shaft and is connected with roller, and input shaft passes through both ends or so spring bearing and right flange shaft
Connect, drive roller to rotate by gear drive thereon on input shaft in roller, input shaft shaft end passes through tapered shaft end in roller
Spline is connected with first gear, and its shortcoming is first gear be the face of cylinder at input shaft cooperation, using key connection, is connected
Key be easily damaged.When first number of gear teeth is few, and root circle is smaller and keyway root is in small distance, first gear is easy
From keyway root cracking damage.
Utility model content
The purpose of this utility model is to provide a kind of circulation lubrication electric roller with external for above-mentioned deficiency, has tooth
Wheel connection is reliable, the characteristics of spring bearing high lubricating effect.
Technical solution of the present utility model is：Circulation lubrication electric roller with external, including roller, roller both ends have
Bearing, roller input have right flange shaft, and motor is realized by shaft coupling, right flange shaft, connection flange and is connected with roller, is inputted
Axle passes through gear drive thereon on input shaft by bearings at both ends and right flange axis connection, in roller and drives roller to rotate, and it is special
Sign is in roller that input shaft shaft end is connected by tapered shaft end with first gear, and output shaft is passed through in corresponding right flange shaft
Oil-through hole.
The utility model has the advantages that：1st, first gear and input shaft connection place use taper connection, improve key
Contact length, and add pretightning force.2nd, oil-through hole is provided between right flange shaft and input shaft, lubricating oil can enter
In input shaft, lubrication is realized to left support bearing, right support bearing, improves bearing service life.
Embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is Fig. 1 along A-A cross-section structure sketches.
Embodiment
Referring to Fig. 1,2, parts title is as follows：First gear 1, right flange shaft 2, input shaft 3, left support bearing 4,
Right support bearing 5, oil-through hole 6, roller 7, bearing 8, motor 9, key 10.
Referring to Fig. 1,2, there is bearing 8 at circulation lubrication electric roller with external, including roller 7, the both ends of roller 7, and roller 7 inputs
There is right flange shaft 2 at end, and motor 9 gos deep into the right realization of flange shaft 2 by input shaft 3 and is connected with roller 7, and it is left that input shaft 3 passes through both ends
Right support bearing 4,5 is connected with right flange shaft 2, drives roller to rotate by gear drive thereon on input shaft in roller 7.Roller
Input shaft shaft end is connected by tapered shaft end with first gear 1 in 7（The shaft end gear of input shaft 3）, improve the contact of key 10
Length, and add pretightning force.There is the oil-through hole 6 for being passed through input shaft 3 in corresponding right flange shaft 2, to left support bearing 4, the right side
Spring bearing 5 realizes lubrication, improves bearing service life.
It is described above, simply specific embodiment of the present utility model, various illustrations are not to reality of the present utility model
Matter Composition of contents limits.
