Description

Encoder elevator motor

Technical Field

The utility model relates to a motor field, concretely relates to encoder lifting machine motor.

Background

The construction elevator is also called as construction elevator for building, and is a manned cargo-carrying construction machine frequently used in building.

In order to realize normal work, a controller of a construction elevator needs to accurately and timely obtain information of the lifting speed, the height, the starting and stopping of the elevator and the like, and a key device for realizing the functions is an encoder. At present, an encoder is mainly installed on a gear middle shaft outside a motor, and the basic working principle of the encoder is that the encoder measures and records information such as the number of turns and the running speed of the gear and feeds the information back to a controller, and the controller finally controls the running state of the elevator. Construction elevator operation environment is the abominable outdoor of environment, and inside rainwater, wind-dust etc. entered into the encoder very easily, the gear drives the chain simultaneously and can produce vibrations when moving, and these all can cause the harm to the encoder, influence the precision and the life of encoder.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that an ability encoder obtains the lifting machine motor of effectual protection for providing.

In order to solve the above and the problems, the utility model adopts the technical proposal that:

the utility model provides an encoder lifting machine motor, includes the casing, locates the stator core in the casing, is located the rotor that the motor shaft supported in the stator core, and the front and rear end of casing are fixed with front end housing, rear end cap respectively, and motor shaft rear end is fixed with the fan after passing rear end cap, arresting gear in proper order, is fixed with the fan housing that covers on arresting gear, fan on the rear end cap.

The braking device and the fan are provided with an encoder assembly, and the encoder assembly comprises a mounting plate, an encoder and a protective cover. The mounting panel is fixed in arresting gear rear end face department, and the encoder is located the protection casing, and the protection casing is fixed in on the mounting panel.

After adopting above-mentioned structure, because the encoder is located inside the motor, under the effect of fan housing and protection casing, the encoder has obtained good protection in order to avoid outside adverse circumstances's influence, and motor rear end basically does not have vibrations to produce simultaneously for the encoder avoids vibrations to influence, has guaranteed the work precision and the life of encoder.

As an improvement of the utility model, be clearance fit between mounting panel, protection casing and the motor shaft, be equipped with first skeleton oil blanket, second skeleton oil blanket between the shaft hole of mounting panel, the shaft hole of protection casing and the motor shaft respectively. After adopting above-mentioned structure, because first skeleton oil blanket and the outstanding dustproof and waterproof wait sealed guard action of second skeleton oil blanket for the encoder avoids the influence of arresting gear and fan, makes the encoder obtain further protection.

Detailed Description

Shown by figure 1, the utility model discloses encoder lifting machine motor, including casing 1, locate stator core 2 in casing 1, be located the rotor 3 that is supported by motor shaft 4 in stator core 2. The front end and the rear end of the casing 1 are respectively fixed with a front end cover 5 and a rear end cover 6, the rear end of the motor rotating shaft 4 sequentially penetrates through the rear end cover 6 and the braking device 7 and then is fixed with a fan 8, and the rear end cover 6 is fixed with a fan cover 9 covering the braking device 7 and the fan 8.

An encoder assembly 10 is arranged between the braking device 7 and the fan 8, and the encoder assembly 10 comprises an encoder 11, a mounting plate 12 and a protective cover 13. The encoder 11 positioned in the protective cover 13 is a spiral encoder, and the encoder 11 is sleeved on and fixed on the motor rotating shaft 4 and rotates synchronously with the motor rotating shaft 4. The mounting plate 12 is fixed to the rear end face of the brake device 7, and the shield 13 is fixed to the mounting plate 12. Mounting panel 12, protection casing 13 all with motor shaft 4 clearance fit, are equipped with first skeleton oil blanket 14, second skeleton oil blanket 15 between the shaft hole of mounting panel 12, the shaft hole of protection casing 13 and the motor shaft 4 respectively.

The protective cover 13 is cylindrical, the front end opening of the protective cover 13 is connected with the mounting plate 12, and the rear end of the protective cover is provided with a plurality of heat dissipation holes. The protective cover 13 has a notch 16, and a power supply line or a signal line outside the motor is connected to the encoder 11 through the notch 16.

During the use, encoder 11 is installed in the inside rear end of motor, and under the combined action of fan housing 9 and protection casing 13, the encoder has obtained good protection in order to avoid outside adverse circumstances's influence, and the motor rear end is basically not shaken simultaneously and is produced for the encoder avoids shaking and influences. Meanwhile, under the excellent sealing protection of the first framework oil seal and the second framework oil seal, such as dust prevention and water prevention, the encoder 11 is also free from the influence of the braking device 7 and the fan 8 inside the motor. The working accuracy of the encoder 11 is guaranteed, the service life of the encoder is guaranteed, and the use cost is reduced.
