CN201344207Y - Coupler of drive roll and speed reducer of loop charging tray - Google Patents

Abstract

The utility model discloses a coupler of a drive roll and a speed reducer of a loop charging tray, which relates to a device used for a longitudinal seam welded pipe and cold bending section production equipment; the coupler comprises a motor, a speed reducer, a roller chain coupling, a bearing seat, a charging tray drive roll and a bearing seat, and is characterized in that the motor drives the speed reducers, and is connected with the roll shaft of the charging tray drive roll by the roller chain coupling through the output shaft of the speed reducer; the charging tray drive roll is connected with the bearing seat by a bearing; the bearing seat supports the charging tray drive roll; wherein the center of the bearing seat is as high as that of the output shaft of the speed reducer; and the bearing seat and the speed reducer are arranged on a bench of the loop charging tray by bolts. The number of the device can be eight to thirty. After the coupler of drive roll and speed reducer of the loop charging tray is adopted, a drive roll shaft is not broken, and the service life of the speed reducer is improved.

Description

The coupling gear of a kind of kink charging tray active roll and speed reducer

Technical field

The utility model relates to a kind of ERW and cold-forming shapes manufacturing mechanism, and particularly a kind of kink charging tray active roll drives the coupling gear with speed reducer output shaft.

Background technique

Charging tray active roll axle head before this directly is loaded on the interior gear of deceleration body, active roll is very long, motor reducer is difficult to guarantee on the plane of planeness precision with being contained in one, high level errors such as initiative roll shaft bearing and speed reducer center height are also very big simultaneously, install under such condition, initiative roll shaft and speed reducer output shaft are difficult to guarantee coaxial accuracy.Initiative roll shaft often ruptures, and speed reducer also damages.Adopt double roller chain coupling to connect initiative roll shaft and no longer rupture, speed reducer improves working life.

Summary of the invention

The purpose of this utility model is for solving the problem that above-mentioned technology exists, and a kind of kink charging tray initiative roll shaft that provides and the coupling gear of speed reducer output shaft.

The utility model solves its technical problem, the technological scheme of being taked is: the coupling gear of a kind of kink charging tray active roll and speed reducer, comprising: motor, speed reducer, double roller chain coupling, bearing support, charging tray active roll, bearing support, it is characterized in that: the motor driving speed reducer, output shaft by speed reducer, through the roll shaft of double roller chain coupling connection charging tray active roll, the charging tray active roll is connected with bearing support through bearing, and bearing support supports the charging tray active roll; Its bottom bracket center and speed reducer output shaft center are contour, by bolt the bearing support speed reducer are installed on the stand of kink charging tray.The number of this device can be 8-30.

The utility model has the advantages that: error is little, and the precision height adopts double roller chain coupling to connect initiative roll shaft and no longer ruptures, and speed reducer improves working life.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

Below in conjunction with drawings and Examples the utility model is described further.

The utility model active roll axle head is that speed reducer output shaft is connected with the active roll axle head with double roller chain coupling with speed reducer connection form.The output shaft of speed reducer and the roll shaft of active roll are connected by double roller chain coupling, and active roll supports by bearing support, and its bottom bracket center and speed reducer output shaft center are contour, by bolt bearing support, speed reducer are installed on the stand of kink charging tray.

Embodiment as shown in Figure 1, motor driving speed reducer 1, the power output shaft by speed reducer 1 connects the roll shaft that passes to charging tray active roll 3 through double roller chain coupling 2, charging tray active roll 3 is realized active rotation.Charging tray active roll 1 is connected with bearing support 3 through bearing, and bearing support 3 plays the effect of supporting charging tray active roll 4.Its bottom bracket 3 centers and speed reducer 1 output shaft center are contour, by bolt bearing support 3 speed reducers 1 are installed on the stand of kink charging tray, and the number of this device is 8-30, and concrete number requires decision by the size and the production line of charging tray.
