Brush DC motor

Abstract: The invention provides a brush DC motor, the both ends of a motor shell is connected fixedly with left and right cover, the left cover is provided with a left bearing location hole and a left bearing, the right cover is provided with a right bearing location hole and a right bearing, the left shaft end of rotor shaft is used for slewing bearing through the left bearing, the right shaft end of rotor shaft is used for slewing bearing through the right bearing, the device is characterized that the right end face of the right shaft outer ring is made axial displacement restricting through Shaft with a collar arranged on rotor shaft; between the left shaft and commutator is provided with conical spring, the small head end of the conical spring is supported with the right side end of the left shaft inner ring, the big end is supported with the bottom end of the commutator, the left side end of the left bearing outer ring is limited by step of the left bearing location hole. The device has the advantages that the stator shaft has the reliable axial displacement restricting, the commutator has simple technology, light weight, low cost, solid structure, good heat dissipation and can meet high speed work requirement.

Pelletizer with vision on -line measuring function

Abstract: The utility model discloses a pelletizer with vision on -line measuring function, including drive arrangement, transmission, main shaft, slewing bearing subassembly, the disc pot body, pot cover, crossbeam, left right side frame, base, on -line measuring module, data processing module, its characterized in that: a left side, right side frame link firmly with crossbeam both ends respectively, drive arrangement loop through transmission, main shaft, slewing bearing subassembly with the power transmission to the disc pot body, but the disc pot body becomes integrative with the pot cover lock, and adopts labyrinth seal, fine motion formula CCD industrial camera in the on -line measuring module, can be with making ball motion the synchronous revolution to that will make ball critical area makes ball developments image acquisition, supplies the data processing module analytic statistics. Compared with the prior art, realize the automatic on -line detection and made ball process work ability, reduced on -the -spot workman's intensity of labour and danger degree, improved the whole automatic level of balling equipment and intelligent level, convenient to popularize and use.

Wind tunnel nozzle 's carousel device

Abstract: The utility model discloses a wind tunnel nozzle's carousel device, including center pin, central bearing, base, carousel lid, rotary support bearing and pneumatic cylinder etc. The center pin is fixed on the ground motionlessly, and central bearing and rotary support bearing use the center pin to rotate as centre of turning circle, and central bearing adopts deep groove ball bearing, and its inner ring cover is on the center pin, and the outer loop is inlayed and is covered at the carousel, rotary support bearing adopts three rows of roller rotary support bearing, and its inner ring is connected with the carousel lid, and the outer loop is connected with the base of fixing on the ground, through the push -and -pull of pneumatic cylinder, realizes the rotation of carousel lid to it realizes that 90 turn to to drive carousel caping portion spray tube. The utility model discloses a general deep groove ball bearing and three rows to roll the central pest slewing ring bearing be pivoted member, simple structure, simple to operate, positioning accuracy is high, uses the maintenance cost low, can bear the load that the carousel caping 100t of portion is heavy, can satisfy wind tunnel nozzle and turn to 90 needs.

Glass fiber composite slewing bearing and manufacturing method thereof

Abstract: The invention relates to a glass fiber composite slewing bearing and a manufacturing method thereof. The glass fiber composite slewing bearing comprises an outer ring, an inner ring and rolling elements, wherein the inner side of the outer ring is matched with the outer side of the inner ring to form a rolling path for allowing the rolling elements to roll on; the outer ring comprises an external glass fiber layer and an internal metal layer integrated with the external glass fiber layer; the section, in the axial direction of the bearing, of the internal metal layer is T-shaped, and a ring-shaped groove A for accommodating the rolling elements is formed in the lower end of the section; a corresponding T-shaped groove is formed in the inner side of the section, in the axial direction of the bearing, of the external glass fiber layer. The glass fiber composite slewing bearing is manufactured by the method comprising the following steps: treating a mould, manufacturing the internal metal layer, placing and positioning the internal metal layer, sealing and closing the mould, conducting mould pressing, and finally conducting curing, forming and trimming. The glass fiber composite slewing bearing provided by the invention has the advantages as follows: the manufacturing method of the glass fiber composite slewing bearing is simple; the outer ring comprises the glass fiber layer and the internal metal layer integrated with the external glass fiber layer, thereby having a good insulating property and being resistant to corrosion.
