The technical solution of the utility model is as follows:
A kind of high line finish rolling cone axle box bearing puller, comprises steel cylinder, hollow circular tube cover and push rod; Described hollow circular tube cover comprises two semicircle steel bushings, and the bottom of described hollow circular tube cover inwall is provided with draw ring; Described steel cylinder is threaded connection at hollow circular tube cover outside, and the bottom of described steel cylinder is provided with middle through hole, and described push rod is threaded connection in middle through hole.
Further: the outer wall of described steel cylinder to be symmetrically arranged with two steel cylinder handles, the outer wall of described steel bushing to be provided with steel bushing handle.
Further: the outer wall of described steel bushing to be provided with steel bushing screw thread, the inwall of described steel cylinder is provided with steel cylinder screw thread, described steel bushing screw thread and described steel cylinder threaded engagement use; The inwall of described middle through hole is provided with middle through hole whorl, the outer wall of described push rod is provided with push rod screw thread, described middle through hole whorl and described push rod threaded engagement use.
Further: described push rod is provided with nut in end, described nut opposite side is globular model.
Technique effect of the present utility model is as follows:
1, the utility model bearing puller improves the efficiency of old bearing removal and installs the quality of new bearing, and then extends service life and the bearing replacing cycle of cone case, decreases the year spare parts consumption in this region.
2, the bearing puller of the utility model embodiment shortens the time of casualty under emergency, alleviates the labour intensity of repairing workman, extends the cone case servo period of spare unit and service time as a whole.
3, the bearing puller structure of the utility model embodiment is simple, light and handy, easily makes, easy to use.
4, remarkable in economical benefits.Use this bearing puller, can bring direct economic benefit to be :+18 hours/year (axis of cone price) × 12 cover/years (year saving) of+6000 yuan, 2500 yuan/cover (bearing price) × 36 cover/years (year saving)/overlap (time of casualty) × 70 ton/hour × 150 yuan/ton of (single ton of profit)=35.1 ten thousand.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, and be not used in restriction the utility model.
As shown in Fig. 1 ~ 5, the structure of high line finish rolling cone axle box bearing puller comprises: steel cylinder 1, hollow circular tube cover 2 and push rod 3; Steel cylinder 1 is threaded connection at hollow circular tube cover 2 outside, and the bottom of steel cylinder 1 is provided with middle through hole 101, and push rod 3 is threaded connection at middle through hole 101 place.
For the ease of operation, the outer wall of steel cylinder 1 is symmetrically arranged with two steel cylinder handles 102, middle through hole 101 is for making push rod 3 penetrate in middle through hole 101 and moving vertically in middle through hole 101.The inwall of steel cylinder 1 is provided with steel cylinder screw thread 103, steel bushing screw thread 203 and steel cylinder screw thread 103 mate and with the use of; The inwall of middle through hole 101 is provided with middle through hole whorl, the outer wall of push rod 3 is provided with push rod screw thread 301, middle through hole whorl and push rod screw thread 301 mate and with the use of, above-mentioned be threaded through turning and formed.
In preferred embodiment, the internal diameter of steel cylinder 1 is 130mm, and external diameter is 155mm, and tube length is 95mm; The diameter of middle through hole 101 is 31mm, and the thickness of the bottom of steel cylinder 1 is 20mm.
Hollow circular tube cover 2 is combined by two semicircle steel bushings 202, the outer wall of hollow circular tube cover 2 (steel bushings 202 after combination) is provided with steel bushing screw thread 203, is provided with draw ring 204 bottom inwall.For the ease of operation, the outer wall of each steel bushing 202 is provided with a steel bushing handle 201.During making, first can cast a hollow circular tube base, then be divided into two, form two semicircle steel bushings 202.
