Description

External electric roller with groove gear transmission

Technical Field

The utility model relates to the field of electric rollers, in particular to an external electric roller with a groove gear transmission.

Background

In the prior art, an external fixed-shaft gear reduction electric roller (hereinafter referred to as an electric roller) is a novel driving device of a belt conveyor, and can replace a driving device consisting of a motor, a speed reducer and a transmission roller which are widely used at present, so that the frame space of the driving device is saved, and the cost is saved. Meanwhile, the shape installation size of the electric roller is matched with the size of a driving roller of a TD75 type and DT II type belt conveyor, and the electric roller is widely applied to the fields of ports, mines, metallurgy, cement, chemical engineering, power plants and the like, creates a large amount of wealth for users, and achieves better performance. The motor is directly connected with a drum input shaft through a coupling, the drum input shaft comprises a right flange input shaft and a left flange shaft which are connected, the inner end of the right flange input shaft in the drum is provided with a pinion which is meshed and connected with an upper gear, the upper gear is provided with a pinion shaft which is meshed and connected with an inner gear ring which is fixedly connected with the inside of the drum. The disadvantage is that the pinion shaft is dangling near the bottom of the drum input shaft and cannot store oil, resulting in the pinion shaft often being damaged by lack of oil. Causing the bearings supporting the pinion shaft to heat up too much and fail. And because the shaft end of the right flange input shaft at the pinion has a hole, the pinion is often damaged due to oil shortage, and the bearing supporting the right flange input shaft is damaged due to overhigh temperature rise.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide the gear transmission external electric roller with the groove, which has a good bearing lubricating effect and prolongs the service life.

The technical solution of the utility model is as follows: the gear transmission external electric drum with the groove comprises a motor and a drum, wherein the motor is directly connected with a drum input shaft through a coupling, the drum input shaft comprises a right flange input shaft and a left flange shaft which are connected, the inner end of the right flange input shaft in the drum is provided with a pinion which is in meshed connection with an upper gear, the upper gear is coaxial and provided with a pinion shaft, the pinion shaft is in meshed connection with an inner gear ring which is fixedly connected with the inside of the drum, and the gear transmission external electric drum is characterized in that an oil storage cavity which is favorable for lubrication is reserved at the position of the pinion shaft, which is close to the bottom of the right flange input shaft; and a second oil storage cavity favorable for lubrication is reserved at the bottom of the pinion.

The utility model has the advantages that: through the improvement that has pertinence to traditional motorized pulley, set up the oil storage chamber in gear, bearing department, satisfy the lubricated demand of bearing, realize that gear, bearing are lubricated effectual, improved life, reduce the fault rate, improved product quality.

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Drawings

FIG. 1 is a schematic diagram of the present invention.

Detailed Description

Referring to fig. 1, the part names are as follows: the device comprises a left support 1, a left end cover 2, a drum 3, a left flange shaft 4, a pinion 5, an upper gear 6, a pinion shaft 7, an inner gear 8, a right end cover 9, a right flange input shaft 10, a right support 11, a coupler 12, a motor 13, an oil storage cavity 14 and a second oil storage cavity 15.

Referring to fig. 1, the grooved gear transmission external electric drum comprises a motor 13 and a drum 3, wherein the motor 13 is directly connected with a drum input shaft through a coupling 12, the drum input shaft comprises a right flange input shaft 10 and a left flange shaft 4 which are connected, a pinion 5 (a shaft directly milling a gear on the shaft or a gear with taper in the inner hole) is arranged at the inner end of the right flange input shaft 10 in the drum 3, a pinion 5 is meshed with an upper gear 6, the upper gear 6 is coaxially provided with a pinion shaft 7, the pinion shaft 7 is meshed with an inner gear 8, and the inner gear 8 is fixedly connected with the inside of the drum 3. An oil storage cavity 14 which is beneficial to lubrication is reserved at the position of the pinion shaft 7 close to the bottom of the right flange input shaft 10; and a second oil storage cavity 15 which is beneficial to lubrication is reserved at the bottom of the pinion 5.

The electric roller adopts a two-stage or three-stage dead axle gear speed reducing structure, so that the requirements of different belt speeds can be met; the motor is external, and heat dissipation and maintenance are convenient, and the commonality is strong, and the gear adopts seven grades of precisions, has the transmission steadily, and bearing capacity is big, and the overload capacity is strong, the noise is low, maintain characteristics such as simple.

The electric roller is matched with different types of motors and can be used in different places, such as: an external explosion-proof electric roller and an external variable-frequency speed-regulating electric roller. The speed reducer in the roller body is lubricated in an oil immersion mode, so that the lubrication of the speed reducer is more reliable. The surface of the electric roller body can be cold-bonded with a rhombic rubber surface or a herringbone rubber surface, and can also be cast, so that the surface friction coefficient is improved, the tension of the conveying belt is reduced, the service life of the adhesive tape is prolonged, the power consumption is reduced, and the energy is saved.

The foregoing description is only exemplary of the utility model and is not intended to limit the spirit of the utility model.
