In order to achieve the above objectives, the pneumatic motor system of this creation to prevent bearing oil leakage includes: The cylinder 'includes a cylinder body, a - cylinder head and a f cylinder head. The cylinder system has an accommodation space, and the cylinder cover is a cylinder cover and is disposed on the cylinder body. And having a first bearing seat bearing and a first blocking piece, wherein the first bearing system is disposed in the first bearing housing, the first bearing system has an inner ring and a surrounding outer ring outer ring 4 Between the inner ring and the outer ring, a ring-shaped v-shaped piece of lubricated grease is formed in a ring shape and disposed between the first bearing seat and the first bearing, and surrounds the annular gap covering the first bearing The first cylinder head cover is disposed at the other end of the cylinder body; the rotor is rotatably disposed in the accommodating space of the cylinder body; the outer peripheral surface thereof is provided with a plurality of blades; and a transmission vehicle is provided by The drive shaft is threaded into the rotor and coupled to the first bearing. Preferably, the second cylinder head has a second bearing seat, a first air bearing first carrier, the second bearing is disposed in the second bearing seat and combined with the transmission shaft, the first The second bearing system has an inner ring and a surrounding ring 6 M343561, the inner ring outer ring, the inner ring and the outer ring, and the annular gap of the grease, the second blocking piece 俜:,: the valley, the inner lubrication Between the oil seat and the second bearing, and surrounding the cover-car bearing wind into a ring of bearings, and the drive shaft is also combined with the second bearing. Preferably, the drive shaft advances: a combined-grinding disc. =This creation is provided with a broadcast piece between each bearing seat and the corresponding bearing. Because the β air intake enters the inside of the cylinder and pushes the rotor*, the steam discharge is blocked by the blocking piece and does not enter the fish body u - 曰Entering the gap between the bearings, the gas does not fit out the grease inside the bearing, so this design has the specific effect of preventing the runoff of the shaft i (7) / by u, so the bearing can maintain a high degree of lubrication and maintain its service life, and then Maintain the durability of the air motor. [Embodiment] The first embodiment and the second figure of the tea are shown. The preferred embodiment of the present invention includes a cylinder (10), a rotor (20) and a transmission shaft (10). The steam red (1) system ★ includes a cylinder. The body (1)), a first cylinder head (12) and a second cylinder cylinder (13) 'the cylinder body (1)) are formed with an accommodating space, and the first cylinder head (丨2) is sleeved on the cylinder One end of the body (11) has a first bearing seat (1), a first bearing (122) and a first blocking piece (123), and the first bearing (122) is disposed on the first bearing In the seat (121), the first bearing (122) has an inner ring (1221) and an outer ring (1222) surrounding the inner ring (1221), the inner ring (1221) and the outer ring (1 222) An annular gap is formed between the first bearing block (121) and the first bearing (122), and is surrounded by the annular gap. The first blocking piece (丨23) is annular and disposed between the first bearing seat (121) and the first bearing (122). The second cylinder head (13) 7 M343561 is disposed at the other end of the cylinder body (11) on the annular gap of the first bearing (1 22); in the preferred embodiment, the The second cylinder cover (13) has a second bearing seat (1 31 ) and a second bearing (1 3 2 ), and the second bearing (13 2 2) is disposed in the second bearing seat (131). The second bearing (132) has an inner ring (1321) and an outer ring (1 322) surrounding the inner ring (1321). The inner ring (1321) and the outer ring (1 322) are formed with a receiving space. An annular gap having a lubricating grease, the second cylinder head (13) further having a second blocking piece (133), the second blocking piece (133) being annular and disposed on the second bearing seat (1 31) Between the second bearing (132) and the annular gap covering the second bearing (1 32); the rotor (20) is rotatably disposed in the cylinder body (in the accommodating space of the 丨d) The outer peripheral surface is provided with a plurality of blades (21), and the transmission shaft (30) is disposed in the rotor (2〇) and combined with the first and second bearings (122) (1 32); In a preferred embodiment, the drive shaft (3〇) can be further eccentrically coupled to a grinding disc (31), so that the preferred embodiment can be applied to a pneumatic grinder. When external intake air enters the cylinder When the body (u) pushes the blade (21) of the rotor (2〇), the rotor (2〇) drives the drive shaft (3〇) to rotate, and when the gas is discharged from the cylinder body (11), due to the bearings ( The gap between 1 22) ( 1 32) is covered by the corresponding blank ( 1 23) ( 1 33), so the gas cannot enter the gap between the bearings ( 1 22) ( 1 32), thus preventing lubrication in the gap. The grease is blown out by the gas to prevent oil leakage from the bearing (1U) (132). Therefore, the rotation of the bearing (1 22) ( 1 32) maintains a high degree of lubrication without causing severe wear, which prolongs the service life of the bearing (1 22) ( 1 32), thereby maintaining the durability of the gas 8 M343561 motor degree. , Pneumatics The preferred embodiment of the present invention is not limited to use on pneumatic grinders, τ applications, any suitable pneumatic tools, including pneumatic screwdrivers and wrenches.
