Abstract
The utility model belongs to the technical field of machining, relates to a transmission device, and specifically relates to a grinding wheel transmission device. The grinding wheel transmission device comprises a bearing base and an unloading belt wheel connected to the rear end of the bearing base, wherein a transmission shaft is supported inside the bearing base by two bearings, the two bearings are separated by a spacer bush, a bearing end cap is connected to the rear part end face of the bearing base through screw fastening, the rear end of the transmission shaft passes through the bearing end cap and is stretched into the cavity of the unloading belt wheel, a pressing cover is disposed on the outer end face of the unloading belt wheel and connected to the transmission shaft by the screw fastening, and a roller chain wheel is connected on shaft diameter of the front end of the transmission shaft by a flat key. The device can effectively avoid the problem during work of an existing grinding wheel transmission device that work of a main shaft is unstable finally, which is caused by motor vibration.
Description
Technical field
The utility model belongs to machining technique field, relates to transmission device, specifically a kind of grinding wheel transmission.
Background technology
Wheel grinding device has a wide range of applications workpiece outside face is polished to add man-hour.The power resources that are installed on the emery wheel on main shaft are mainly external motors, and transmission device is connected motor output end with grinding wheel spindle.Existing transmission device is by crosshead shoe, the clutch end of transmission device to be connected with the input of grinding wheel spindle mostly, because motor can produce vibration when working, bring unstable, the transmission device of existing structure can be directly passed to grinding wheel spindle by the vibration of motor and other destabilizing factors, causes the unstability of wheel grinding workpiece.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of grinding wheel transmission simple in structure, ingenious, rational is provided, this device can effectively avoid existing grinding wheel transmission when work, because motor shakes, and causes the problem of final main shaft job insecurity.
The technical scheme providing according to the utility model: a kind of grinding wheel transmission, be characterised in that: comprise bearing block and be connected in the belt pulley of bearing block rear end, power transmission shaft is supported in bearing block by two bearings, between two bearings, pass through spacer separately, at the rear portion of bearing block, end face is connected with bearing (ball) cover by screw fastening, power transmission shaft rear end is passed bearing (ball) cover, is stretched in belt pulley inner chamber, gland is arranged at end face outside belt pulley, and be fastenedly connected by screw and power transmission shaft, on the described power transmission shaft front end diameter of axle, by flat key, be connected with roller chain wheel.
As further improvement of the utility model, described bearing block inner ring front portion is formed with stopper, the junction in described stopper and bearing block inner ring rear bearings chamber is provided with a circle breach, in bearing block, be also provided with back-up ring, the drift angle of described back-up ring stretches in breach, and back-up ring rear portion lug boss holds out against on the outer ring of the bearing being attached thereto.
As further improvement of the utility model, the axis hole of described belt pulley is large, the interior young circular cone shape of collar extension, and power transmission shaft rearward end matches with belt pulley circular cone shape inner chamber.
The utility model compared with prior art, advantage is: the utility model product is by providing brand-new belt input transmission device and by the external output device of roller chain wheel in wheel grinding device, can effectively avoid the vibration of motor-driven and various destabilizing factor to take that main shaft gets on to and the situation that causes finally processing substandard product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, comprise bearing block 1, stopper 1-1, breach 1-2, off-load belt pulley 2, gland 3, power transmission shaft 4, bearing (ball) cover 5, spacer 6, bearing 7, back-up ring 8, roller chain wheel 9 etc.
As shown in Figure 1, a kind of grinding wheel transmission of the utility model, comprise bearing block 1 and be connected in the off-load belt pulley 2 of bearing block 1 rear end, power transmission shaft 4 is supported in bearing block 1 by two bearings 7, between two bearings 7, pass through spacer 6 separately, at the rear portion of bearing block 1, end face is connected with bearing (ball) cover 5 by screw fastening, power transmission shaft 4 rear ends are through bearing (ball) cover 5, stretch in off-load belt pulley 2 inner chambers, gland 3 is arranged at off-load belt pulley 2 outside end faces, and be fastenedly connected by screw and power transmission shaft 4, on the described power transmission shaft 4 front end diameters of axle, by flat key, be connected with roller chain wheel 9.
Described bearing block 1 inner ring front portion is formed with stopper 1-1, the junction in described stopper 1-1 and bearing block 1 inner ring rear bearings chamber is provided with a circle breach 1-2, in bearing block 1, be also provided with back-up ring 8, the drift angle of described back-up ring 8 stretches in breach 1-2, and back-up ring 8 rear portion lug bosses hold out against on the outer ring of the bearing being attached thereto.
The axis hole of described off-load belt pulley 2 is large, the interior young circular cone shape of collar extension, and power transmission shaft 4 rearward end match with off-load belt pulley 2 circular cone shape inner chambers.
The utility model product, when work, is fastenedly connected external roller chain wheel realization in roller chain wheel outside by pin the transmission of power of off-load belt pulley 2 is gone out; Specifically on off-load belt pulley 2, be arranged with belt, when off-load belt pulley 2 rotates, drive power transmission shaft 4 in the interior rotation of bearing block 1, by power transmission shaft 4, drive roller chain wheel 9 synchronously to rotate, roller chain wheel 9 to external piece, is realized the object of power output by transmission of power.
