Abstract
The utility model relates to a dismounting device of a saddle nut, which comprises a dismounting head device, a motor, a machine frame and a box body of a gear box. The lower end of the box body of a gear box is provided with a support seat on which a through hole connected with a bolt of the machine frame is arranged, and the periphery of a front flange of the dismounting head device presents a cylinder shape and is provided with at least five through holes connected with a bolt of an elbow umbrella gear shell. Because the support seat and the box body of a gear box form a whole, when the utility model works, the stress concentrates on the box body of the gear box, and the motor is more stable; the front flange is additionally provided with the bolt so that the front flange is firmly connected with the elbow umbrella gear shell.
Description
Technical field:
The utility model relates to car mechanic's tool, particularly the nut changer of vehicle saddle nuts.
Background technology:
In the vehicle maintenance industry, the saddle nuts changer is indispensable repair outfit, uses very extensively along with large-tonnage lorry, passenger vehicle, requires more and more higher to the torsion of changer.The bearing of saddle nuts changer is to be connected by bolt with electric machine casing at present, because the power transmission shaft and the tube connector thereof of dismounting head are longer, the gear box casing below is unsettled, changer produces bigger torsion during work, on the stressed bolt that directly concentrates on motor drive end bearing bracket and gear box casing, bolt loosening easily or gear box casing or the fracture of motor drive end bearing bracket cause the indefinite or damage of motor swing.Forward flange is a rectangle in addition, is connected forward flange by four bolts with elbow umbrella tooth shell, and the also loosening easily or fracture of connecting bolt causes forward flange to come off.
Summary of the invention:
The purpose of this utility model provides that a kind of motor stabilizing is good, drive end bearing bracket not easy fracture, saddle nuts changer that the forward flange fastness is good.
The utility model comprises dismounting head unit, motor, frame and gear box casing, and the gear box casing lower end is shaped on bearing, has on the bearing and the bolted through hole of frame.
The bearing bottom surface of gear box casing rectangular or " worker " font or " two " font.Another kind of gear box casing is a split-type structural, is connected with bolt of rear case by procapsid.The forward flange periphery of dismounting head unit is cylindrical, has at least 5 and the bolted through hole of elbow umbrella tooth shell.
The utility model has the advantages that: because bearing and gear box casing form one, stressed gear box casing and the bearing thereof of concentrating on during work, the motor stabilizing raising, forward flange has increased bolt, makes forward flange be connected more firm with elbow umbrella tooth shell.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is a gear box casing schematic diagram of the present utility model.
Fig. 3 is the another kind of gear box casing schematic diagram of the utility model.
The specific embodiment:
With reference to Fig. 1, the saddle nuts changer comprises dismounting head unit 3, motor 1, frame 6 and gear box casing 2, and wherein dismounting head unit 3 is made up of tube connector, forward flange 4, elbow umbrella tooth shell 5, gear train, square shaft etc.Gear box casing 2 is made one with bearing 2.1, has four through holes 2.2 on the bearing 2.1, is connected with frame 6 by bolt, and motor 1 lower end is the chord seat not.The forward flange 4 of dismounting head unit 3 is peripheral cylindrical, has eight through holes, is connected with elbow umbrella tooth shell 5 by bolt.In addition, a bearing and a separation pad are housed between original power transmission shaft and the elbow umbrella tooth,, also change separation pad into bearing for reducing kinetic equation loss.
As shown in Figure 2, gear box casing 2 forms one with bearing 2.1, and the bottom surface is " worker " font, and the bottom surface also can be made into rectangle or " two " font.
As shown in Figure 3, gear box casing 2 is a split-type structural, is made up of procapsid 2.3 and back casing 2.4, and is bolted to connection.
