Description
Technical field: the present invention relates to bearing grinder roller dressing technique, especially sealing gland formula roller shaft and method of work.
Background technology: bearing grinder roller burring machine is mainly grease lubrication at present, is not suitable for rotation at a high speed, and sealing effectiveness is bad, and maintenance cost is high, brings very big inconvenience to production and processing.
Summary of the invention: it is long to the purpose of this invention is to provide a kind of life-span, sealing gland formula roller shaft and method of work that efficient is high, and it has overcome the shortcoming that original technology exists; The objective of the invention is to realize like this; It is little round nut, synchronous pulley, axle sleeve, passes through lid, tapered sleeve, clutch shaft bearing, big bearing block, main shaft, big round nut, second bearing, gland, shaft end ring, housing screw, quick connector, small bearing bracket and emery wheel and be formed by connecting, and little round nut is fixed on the main shaft, and compresses synchronous pulley; The synchronous pulley other end compresses axle sleeve; The axle sleeve other end compresses the inner ring of clutch shaft bearing, and the inner ring of clutch shaft bearing compresses tapered sleeve, and tapered sleeve and main shaft lean on cone match; Pass through lid and be fixed on the big bearing block, and compress the outer ring of clutch shaft bearing.
Big round nut is fixed on the main shaft and compresses emery wheel; All the external diameter than small bearing bracket is big for the endoporus of big round nut and emery wheel, is convenient to change emery wheel.
Gland is fixed on the small bearing bracket, and compresses the outer ring of second bearing, and shaft end ring compresses the inner ring of second bearing through housing screw, and quick connector is fixed on the gland, and quick connector is used for connecing the mist of oil tracheae.
Passage is arranged on the housing screw, passage is arranged on the main shaft, can make the lubricated bearing to two ends of lubricator body like this, the mist of oil gas of access requires to have the pressure of 0.2MP, has so just played the effect of sealing gland, prevents impurity entering bearings at both ends positions such as steam.
Method of work of the present invention: the aerosol lubrication hole is arranged on main shaft and the gland, before the machine operation, will open source of the gas, to bearing fog lubrication, the lubricated maintenance bearing can also play the effect of hermetic seal constantly, prevents that outside steam from getting into axle bed; Also want big owing to compress the external diameter of interior boring ratio small bearing bracket of the big round nut of emery wheel, only need unload the emery wheel that big round nut just can more renew very easily when changing emery wheel.
The invention has the beneficial effects as follows: this device not only can satisfy the requirement of quick replacing emery wheel, and is added with fog lubrication and sealing gland function, does not need regular pair roller bearing to safeguard that maintenance cost is low; Prolonged the service life of bearing, improved the operating efficiency of lathe, main shaft adopts double supporting structure, has improved integral rigidity, can guarantee dressing accuracy.
Description of drawings: Fig. 1 is a sealing gland formula roller shaft structural representation, among the figure 1, roundlet nut 2, synchronous pulley 3, axle sleeve 4, cover 5 thoroughly, tapered sleeve 6, clutch shaft bearing 7, big bearing block 8, main shaft 9, big round nut 10, second bearing 11, gland 12, shaft end ring 13, housing screw 14, quick connector 15, small bearing bracket 16, emery wheel
The specific embodiment: embodiment 1, the present invention be on roundlet nut 1, synchronous pulley 2, axle sleeve 3, cover 4 thoroughly, tapered sleeve 5, clutch shaft bearing 6, big bearing block 7, main shaft 8, big round nut 9, second bearing 10, gland 11, shaft end ring 12, housing screw 13, quick connector 14, small bearing bracket 15, and emery wheel 16 be formed by connecting; Roundlet nut 1 is fixed on the main shaft 8; And compress synchronous pulley 2; Synchronous pulley 2 other ends compress axle sleeve 3; Axle sleeve 3 other ends compress the inner ring of clutch shaft bearing 6, and the inner ring of clutch shaft bearing 6 compresses tapered sleeve 5, and tapered sleeve 5 leans on cone match with main shaft 8; Cover 4 thoroughly and be fixed on the big bearing block 7, and compress the outer ring of clutch shaft bearing 6.
On embodiment 4, the housing screw 13 passage is arranged; On the main shaft 8 passage is arranged, can make the lubricated bearing to two ends of lubricator body like this, the mist of oil gas of access requires to have the pressure of 0.2MP; So just play the effect of sealing gland, prevented impurity entering bearings at both ends positions such as steam.
