Abstract
The utility model discloses a belt transmission device, which is capable of preventing belt sag, comprising a decelerator (2) mounted on a frame (1); a motor mounting plate (3) which is mounted on the frame (1) and inclinedly arranged at an angle of a 50 to 80 DEG with the horizontal plane of the frame (1); a long fixing hole (4) which is arranged on the motor mounting plate (3) and slidingly connected with a motor (5); a small belt wheel (6) which is mounted on the motor shaft and connected with a large belt wheel (8) arranged on a decelerator (2) through a ring belt (7). By mounting the motor of the utility model on an inclined motor mounting plate, the motor is capable of sliding along the long fixing hole under the function of self weight, therefore the distance between the small belt wheel and the large belt wheel is increased, the transmission belt is stretched automatically and can not sag. The utility model has simple structure, economical practicality, and convenient maintenance.
Description
Technical field
The utility model relates to a kind of transmission device, particularly a kind of belt drive unit that prevents belt slack.
Background technique
In the belt drive unit of motor and retarder, drivign belt used after a period of time can influence transmission efficiency because elongate or the loosening belt that makes of motor set screw fluffs, sometimes even the phenomenon that can occur skidding.This address this problem, the hole that long strip is processed in the hole of motor generally will be installed, during installation with tension on belt, and then with the screw and the nut screwing clamping of fixed electrical machinery; After using a period of time, the factors such as pulling force that are subjected to during owing to vibration or transmission, it is lax that belt still can become.
The model utility content
The purpose of this utility model is, a kind of belt drive unit that prevents belt slack is provided.Belt in use can not relaxed, with the transmission efficiency that improves belt with prevent belt slippage.
The technical solution of the utility model: a kind of belt drive unit that prevents belt slack comprises rack-mounted retarder; Also be provided with motor mounting plate on the frame, become 50～80 ° to be obliquely installed between motor mounting plate and the horizontal plane of frame; Motor mounting plate is provided with long fixed hole, and long fixed hole and motor are slidingly connected; Small belt pulley is installed on the motor shaft, and small belt pulley is connected with big belt pulley on being located at retarder through endless-belt.
In the above-mentioned belt drive unit that prevents belt slack, described motor is connected with long fixed hole with nut by set screw.
Compared with prior art, because motor is installed on the motor mounting plate of inclination, motor is in use vibrated or becoming flexible owing to set screw, motor is under the effect of own wt, can glide along long fixed hole, thereby increased the spacing between small belt pulley and the big belt pulley, made not relax the drivign belt auto-tensioning.Thereby can guarantee that transmission efficiency can not reduce, belt can not skid on belt pulley yet.The utility model is simple in structure, and is economical and practical, is convenient to safeguard.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Being labeled as in the accompanying drawing: 1-frame, 2-retarder, 3-motor mounting plate, the long fixed hole of 4-, 5-motor, 6-small belt pulley, 7-endless-belt, 8-big belt pulley, 9-set screw.
Embodiment
Below in conjunction with drawings and Examples a kind of belt drive unit of belt slack that prevents of the present utility model is described in further detail, but not as the foundation of the utility model being done any restriction.
Embodiment.A kind of belt drive unit that prevents belt slack of the present utility model, as shown in Figure 1.Comprise the retarder 2 that is installed on the frame 1; Also be provided with motor mounting plate 3 on the frame 1, become 50～80 ° to be obliquely installed between motor mounting plate 3 and frame 1 horizontal plane; Motor mounting plate 3 is provided with long fixed hole 4, and long fixed hole 4 is slidingly connected with motor 5; Small belt pulley 6 is installed on the motor shaft, and small belt pulley 6 is connected with big belt pulley 8 on being located at retarder 2 through endless-belt 7.Motor 5 is connected with long fixed hole 4 with nut by set screw 9.
Working principle of the present utility model
Because motor is installed on the motor mounting plate of inclination, motor is in use vibrated or becoming flexible owing to set screw, motor is under the effect of own wt, can glide along long fixed hole, thereby increased the spacing between small belt pulley and the big belt pulley, make and can not relax the drivign belt auto-tensioning.Thereby can guarantee that transmission efficiency can not reduce, belt can not skid on belt pulley yet.
Claims (2)
- [claim 1] a kind of belt drive unit that prevents belt slack comprises the retarder (2) that is installed on the frame (1); It is characterized in that: also be provided with motor mounting plate (3) on the frame (1), become 50～80 ° to be obliquely installed between motor mounting plate (3) and frame (1) horizontal plane; Motor mounting plate (3) is provided with long fixed hole (4), and long fixed hole (4) is slidingly connected with motor (5); Small belt pulley (6) is installed on the motor shaft, and small belt pulley (6) is connected with big belt pulley (8) on being located at retarder (2) through endless-belt (7).
