Description

The rotating actuator of revolving restaurant

Technical field

The utility model relates to a kind of rotating actuator of revolving restaurant.

Background technology

At present, the rotation of revolving restaurant has the transmission of pin tooth and two kinds of drive mechanisms of frictional drive.The transmission of pin tooth is that motor passes through the rotation of reducer driving pinion, pinion is stirred bearing pin driven rotary dish and the turntable rotation on the pin wheel, because structure and processing technology are limit, the contact surface of pin tooth transmission can't guarantee contact precision, wearing and tearing are very fast, wearing clearance can't compensate, and must change component to certain hour, otherwise can't continue normal use; Because the gap of contact surface can't compensate at the volley, cause that the equipment running noises is big, vibrations are big; Selling the tooth transmission in addition can only transfer torque, can not bear turning torque and axial load, in order to bear the turning torque of load and balance turntable, must arrange several support wheels at the rotating disk lower plane, this has just increased processing, mounting hardness greatly, has further increased noise and the vibrations in the running simultaneously.Frictional drive is to transmit turning moment by several friction pulleys that drive separately that are arranged in below the turntable by frictional force, this structure is very high to the material requirements of friction pulley, also cause wearing and tearing easily, equally with the transmission of pin tooth also need to arrange several support wheels, manufacturing and installation accuracy require more taller than the transmission of pin tooth, because the frictional drive precision is not high, may produces Elastic Sliding and skid between two friction pulleys simultaneously, transmission efficiency is low.The difficulty of above-mentioned two kinds of scheme processing and manufacturings and Installation and Debugging is big, cost is high, and the maintenance cost of day-to-day operation is also very high.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, and a kind of rotating actuator of revolving restaurant is provided, and it can improve accuracy, the stationarity of transmission, reduces equipment running noises, vibrations, reduces device fabrication and mounting hardness, cost.

Technical solutions of the utility model are: the rotating actuator of revolving restaurant, by turntable, rotating disk, base, Slewing Support Mechanism, reduction gearing mechanism, reducer, motor is formed, described Slewing Support Mechanism comprises gear ring, ball, separation sleeve, inner ring, lubricating arrangement, gear ring is sleeved on outside the inner ring, the periphery of inner ring and the inner headed face of gear ring are both mating faces, at the upper edge, mating face of gear ring and inner ring circumference one corresponding cross section being arranged respectively is semicircular raceway, thereby form a circular cross-section raceway, one radial hole is arranged on the inner ring, the ball of some and separation sleeve are put into raceway by described radial hole successively at interval, until filling, the two sides of described separation sleeve are the spheres identical with ball diameter, installing one in the described radial hole stops up, with radial hole and the vertical taper hole that passed through mutually of obstruction, have a taper pin to be contained in the taper hole, described lubricating arrangement is that raceway adds lubrication oil, and the seam crossing up and down on the mating face of gear ring and inner ring is equipped with dust ring; Described inner ring is connected with bolt with base along circumference, and described gear ring is connected with bolt with rotating disk along circumference; Described reduction gearing mechanism is mounted in the pinion on the reducer output shaft and the engaged transmission of gear ring.

In the rotating actuator of above-mentioned revolving restaurant, motor also can be selected frequency-conversion and speed-regulation motor for use, can realize stepless speed regulation in the scope of safety.

The utility model technology adopts the gear drive scheme of incorporate pivoting support, Slewing Support Mechanism comes down to the application of a big ball bearing, therefore can bear axial load can bear turning torque again, thereby substitute the support wheel in tooth transmission of traditional scheme pin or the friction pulley transmission, designs simplification, device fabrication and installation difficulty and cost are reduced.Adopt gear drive to increase the accuracy and the stationarity of transmission, reduced rotational noise and vibrations with respect to transmission of pin tooth or friction pulley transmission.
